A 20.38 gram sample of cobalt is heated in the presence of excess sulfur. A metal sulfide is formed with a mass of 31.47 g. Determine the empirical formula of the metal sulfide.

Answers

Answer: The empirical formula of the metal sulfide is \(CoBr_{2}\).

Explanation:

Given: Mass of metal = 20.38 g

Mass of metal sulfide = 31.47 g

Moles is the mass of a substance divided by its molar mass.

So, moles of cobalt (molar mass = 59 g/mol) are as follows.

\(Moles = \frac{mass}{molarmass}\\= \frac{20.38 g}{59 g/mol}\\= 0.345 mol\)

Moles of bromine (molar mass = 80 g/mol) are as follows.

\(Moles = \frac{(31.47 - 20.38) g}{80 g/mol}\\= \frac{11.09 g}{80 g/mol}\\= 0.138 mol\)

Now, the ratio of number of moles of cobalt and number of moles of bromine are as follows.

Moles of Co : Moles of Br = 1 : 2

Hence, the empirical formula is \(CoBr_{2}\).

Thus, we can conclude that the empirical formula of the metal sulfide is \(CoBr_{2}\).

write three disadvantages of hard water.​

Answers

The three disadvantages of hard water are:

1. Hard water is unsuitable for washing because soap does not readily create a lather in it.

2. Soap may react and produce, wasting the soap.

3. Due to the development of calcium and magnesium carbonates, tea kettles will get furred.

Hard water

Water that contains a lot of minerals is referred to as hard water. In limestone, chalk, or gypsum deposits, which are mostly composed of calcium and magnesium carbonates, bicarbonates, and sulphates, hard water is created as a result of percolation. A moderate health advantage from drinking hard water is possible. In industrial settings where water hardness is regulated to prevent expensive breakdowns in boilers, cooling towers, and other water-handling equipment, it can present serious issues. Hard water is frequently detected in home settings by the build-up of lime scale in kettles and water heaters as well as by the absence of foam when soap is agitated in water. Wherever there is a worry about water hardness, water softening is frequently employed to lessen the negative impacts of hard water.

Answers

D. molecules containing chlorine and fluorine that block UV radiation from reaching the Earth.

Chlorofluorocarbons (CFCs) are synthetic compounds that contain chlorine, fluorine, and carbon. They were widely used in the past as refrigerants, propellants in aerosol products, and foam-blowing agents. CFCs have been found to have a detrimental effect on the Earth's ozone layer when released into the atmosphere. They can reach the stratosphere, where they undergo a chemical reaction facilitated by ultraviolet (UV) radiation, resulting in the release of chlorine atoms. These chlorine atoms then participate in a destructive cycle that breaks down ozone molecules, leading to ozone depletion. Due to their harmful impact on the ozone layer, the production and use of CFCs have been phased out or regulated under international agreements like the Montreal Protocol to protect the Earth's ozone layer.

Chlorofluorocarbons (CFCs) are man-made chemicals containing chlorine and fluorine that cause ozone molecules to break down. Thus, option B is the answer.

Chlorofluorocarbons are non-toxic, synthetic compounds that contain atoms of Chlorine, Fluorine and Carbon. They are commonly used in the manufacture of aerosol sprays and are also used as solvents and refrigerants. CFCs were first introduced in 1928 by General Motors Company for its refrigerators.

While CFCs are very safe to use in most applications and are stable in the lower atmosphere, these chemicals when released to the upper atmosphere can cause significant reactions. CFCs when released into the upper atmosphere can lead to the destruction of the ozone molecules followed by the release of the UV radiation into the atmosphere.

Thus, CFCs are man-made chemicals which cause ozone molecules to break down.

the equation (i'm too lazy to write states of matter and since it doesnt matter in this problem i'm not going to. it is balanced, however) is:

A mass of 10.05 g of a hydrated barium chloride (BaCl2× xH₂O) is placed in a crucible and heated. After heating, 8.57 g of an anhydrous barium chloride (BaCl2) remains. What is the formula and the name of the hydrate?

Please explain how to do it!​

Answers

The formula for the hydrate is BaCl₂ × ₀.₀₈₂H₂O, and the name of the hydrate is Barium Chloride Monohydrate.

Calculating the value of "x" in the combination BaCl₂ × ₓH₂O will help us discover the hydrate's formula and name. The mass of water that was contained in the hydrate is represented by the difference between the mass before and after heating.

Mass of hydrated barium chloride (BaCl₂ × ₓH₂O) = 10.05 g

Mass of anhydrous barium chloride (BaCl₂) = 8.57 g

To find the mass of water lost:

Mass of water lost = Mass of hydrated barium chloride - Mass of anhydrous barium chloride

= 10.05 g - 8.57 g

= 1.48 g

Thus, the molar mass of water (H₂O) is 18.015 g/mol, calculate the number of moles of water lost:

Moles of water lost = Mass of water lost ÷ Molar mass of water

= 1.48 g ÷ 18.015 g/mol

= 0.082 moles

Now compare the moles of water lost to the moles of anhydrous barium chloride that are still present, in order to calculate the value of "x" in the hydrate formula BaCl₂ × ₓH₂O.

One mole of hydrated barium chloride loses "x" moles of water to produce one mole of anhydrous barium chloride, as shown by the chemical equation.

Moles of anhydrous barium chloride = 1 mole

The ratio of moles of water get reduced to moles of anhydrous barium chloride is 1:x, we can set up the following equation:

0.082 moles (water) ÷ 1 mole (anhydrous barium chloride) = 1:x

To solve for x:

x = 0.082

Thus, the formula for the hydrate is BaCl₂ × ₀.₀₈₂H₂O. Hence, name the hydrate, we use the prefix "mono" for the subscript 0.082. The name of the hydrate is Barium Chloride Monohydrate.

Nitrogen and hydrogen combine at a high temperature, in the presence of a catalyst, to produce ammonia.

N2(g)+3H2(g)⟶2NH3(g)

There are four molecules of nitrogen and nine molecules of hydrogen present in the diagram.

When the reaction is complete, how many molecules of NH3 are produced?
What is the limiting reactant?
How many molecules of each reactant are remain after the reaction is complete?

Answers

After the reaction is complete, no nitrogen and no hydrogen molecules remain, and 8.00 x 1014 molecules of NH3 are produced.

In the equation, nitrogen and hydrogen react at a high temperature, in the presence of a catalyst, to produce ammonia, according to the balanced chemical equation:N2(g)+3H2(g)⟶2NH3(g)The coefficients of each molecule suggest that one molecule of nitrogen reacts with three molecules of hydrogen to create two molecules of ammonia.

So, to determine how many molecules of ammonia are produced when four nitrogen and nine hydrogen molecules are present, we must first determine which of the two reactants is the limiting reactant.

To find the limiting reactant, the number of moles of each reactant present in the equation must be determined.


Calculations:
Nitrogen (N2) molecules = 4Hence, the number of moles of N2 = 4/6.02 x 1023 mol-1 = 6.64 x 10-24 mol
Hydrogen (H2) molecules = 9Hence, the number of moles of H2 = 9/6.02 x 1023 mol-1 = 1.50 x 10-23 mol


Now we have to calculate the number of moles of NH3 produced when the number of moles of nitrogen and hydrogen are known, i.e., mole ratio of N2 and H2 is 1:3.


The mole ratio of N2 to NH3 is 1:2; thus, for every 1 mole of N2 consumed, 2 moles of NH3 are produced.
The mole ratio of H2 to NH3 is 3:2; thus, for every 3 moles of H2 consumed, 2 moles of NH3 are produced.
From these mole ratios, it can be observed that the limiting reactant is nitrogen.


Calculation for NH3 production:
Nitrogen (N2) moles = 6.64 x 10-24 moles
The mole ratio of N2 to NH3 is 1:2; therefore, moles of NH3 produced is 2 × 6.64 × 10−24 = 1.33 × 10−23 moles.


Now, to determine how many molecules of NH3 are produced, we need to convert moles to molecules.
1 mole = 6.02 x 1023 molecules
Thus, 1.33 x 10-23 moles of NH3 = 8.00 x 1014 molecules of NH3 produced.


To find the amount of each reactant remaining after the reaction is complete, we must first determine how many moles of nitrogen are consumed, then how many moles of hydrogen are consumed, and then subtract these from the initial number of moles of each reactant.

The moles of nitrogen consumed = 4 moles × 1 mole/1 mole N2 × 2 mole NH3/1 mole N2 = 8 moles NH3
The moles of hydrogen consumed = 9 moles × 2 mole NH3/3 mole H2 × 2 mole NH3/1 mole N2 = 4 moles NH3
Thus, the moles of nitrogen remaining = 6.64 × 10−24 mol – 8 × 2/3 × 6.02 × 10^23 mol-1 = 5.06 × 10−24 mol
The moles of hydrogen remaining = 1.50 × 10−23 mol – 4 × 2/3 × 6.02 × 10^23 mol-1 = 8.77 × 10−24 mol

Finally, the number of molecules of each reactant remaining can be calculated as follows:
Number of N2 molecules remaining = 5.06 × 10−24 mol × 6.02 × 10^23 molecules/mol = 3.05 × 10−1 molecules ≈ 0 molecules
Number of H2 molecules remaining = 8.77 × 10−24 mol × 6.02 × 10^23 molecules/mol = 5.28 × 10−1 molecules ≈ 0 molecules.

A 11.77 g sample of a compound contains 7.51 g of iron, Fe, 1.39 g of phosphorus, P, and oxygen, O. Calculate the empirical formula for the compound.

Answers

Considering the definition of empirical formula, the empirical formula for the compound is Fe₃PO₄.

Definition of empirical formula

The empirical formula is the simplest expression to represent a chemical compound, which indicates the elements that are present and the minimum proportion in whole numbers that exist between its atoms.

Empirical formula in this case

In this case, in first place you need to convert the number of grams given into percentage as follow:

Iron (Fe): (7.51 g÷ 11.77 g)× 100= 63.81%Phosphorus (P): (1.39 g÷ 11.77 g)× 100= 11.81%Oxygen (O): (2.87 g÷ 11.77 g)× 100= 24.38%

Assuming a 100 grams sample, the percentages match the grams in the sample. So you have 63.81 grams of iron, 11.81 grams of phosphorus and 24.38 grams of oxygen.

Then it is possible to calculate the number of moles of each atom in the molecule, taking into account the corresponding molar mass:

Iron (Fe): 63.81 g÷ 55.85 g/mole= 1.14 molesPhosphorus (P): 11.81 g÷ 31 g/mole= 0.38 molesOxygen (O): 24.38 g÷ 16 g/mole= 1.52 moles

The empirical formula must be expressed using whole number relationships, for this the numbers of moles are divided by the smallest result of those obtained. In this case:

Iron (Fe): 1.14 moles÷ 0.38 moles= 3

Phosphorus (P): 0.38 moles÷ 0.38 moles= 1

Oxygen (O): 1.52 moles÷ 0.38 moles= 4

Therefore the Fe: P: O mole ratio is 3: 1: 4

Finally, the empirical formula is Fe₃P₁O₄= Fe₃PO₄.

A) drawing (1)                                  B) drawing (2)

D) drawing (4)                                  C) drawing (3)

Answer:

   B) drawing (2)

Explanation:

In Chemistry, the direction of dipole is shown from positive end to negative end.

The image that contains the options in the question asked has been attached.

We can see in image 2 that the oxygen atom was correctly designated as the negative end of the dipole while the carbon and hydrogen atoms were each designated as positive ends of the dipole in accordance with the magnitude of electronegativity difference between the two atoms. The net dipole moment is now taken in the direction shown in image 2. This is the correct answer.

Which drawing best accounts for the polarity of methanol, CH3OH, and the bond polarities that make a

Drawing 2 best accounts for the polarity of methanol, CH3OH. Therefore, the correct option is B.

A carbon atom (C) joins with three hydrogen atoms (H), a hydroxyl group (OH), and three other atoms to form methanol (CH3OH). An oxygen atom (O) is attached to a hydrogen atom to form a hydroxyl group. The three hydrogen atoms and hydroxyl groups are arranged in three dimensions, giving the molecular structure of methanol a tetrahedral form around the core carbon atom.

A polar covalent bond is formed between oxygen and hydrogen because the oxygen atom in the hydroxyl group is more electronegative than the carbon and hydrogen atoms. Due to the unequal sharing of electrons, oxygen has a partial negative charge (-) and hydrogen has a partial positive charge (+), resulting in this polarity.

So, the correct option is B.

the solubility of a gas at 7.0 atm of pressure is 0.52g/L. how many grams of the gas would be dissolved per 1.0 L if the pressure increased 40.0 percent

Answers

If the pressure increased 40.0 % 0.728 g/L the gas will be dissolved per 1.0 L.

Henry's Law, which states that the solubility of a gas in a liquid is exactly proportional to the partial pressure of the gas above the liquid.

To determine the new solubility of the gas when the pressure increases by 40%.

Firstly, find the new pressure after the 40% increase:

New pressure = 7.0 + (40% of 7.0)

= 7.0 atm + (0.4 × 7.0 atm)

= 7.0 atm + 2.8 atm

= 9.8 atm

Next, use the new pressure to find the new solubility:

New solubility = (new pressure ÷ Initial pressure) × Initial solubility

= (9.8 atm ÷ 7.0 atm) × 0.52 g/L

= 1.4  × 0.52 g/L

New solubility =  0.728 g/L

Thus, if the pressure rise by 40%, the new solubility of the gas is 0.728 g/L.
