Answer:

D

Explanation: (:

The cation of an ionic compound affects the appearance of the solution by determining the color of the solution.

An ionic compound is formed when an element that has fewer electrons loses them to another element that needs more electrons, forming an ionic bond between them. Ionic bonds are formed between oppositely charged ions. The positively charged ion is referred to as the cation while the negatively charged ion is referred to as the anion.

In an aqueous solution, the presence of a cation is an essential factor that influences the color of the solution. The concentration and identity of cations determine the color of the solution. For example, the presence of a sodium cation will make the solution turn yellow. The color of the solution changes if another cation replaces the sodium cation. The presence of another cation like copper(II) will cause the solution to turn blue.

The total mass of reactants taken = 15.9 + 20.0 = 35.9 gm. From the conservation of mass the final mass of the contents of the vessel should also be 35.9 gm. But it is only 29.3 gm. The difference is due to the mass of released carbon dioxide gas.Hence the mass of carbon dioxide gas released = 35.9 – 29.3 = 6.6 gm

An ionic compound is a giant structure of ions. The ions have a regular, repeating arrangement called an ionic lattice . The lattice is formed because the ions attract each other and form a regular pattern with oppositely charged ions next to each other.

The balanced chemical reaction for the combustion of glucose (C6H12O6) can be represented as follows:
C6H12O6(s) + 6O2(g) -> 6CO2(g) + 6H2O(g)

In this reaction, glucose (C6H12O6) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O).

To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. In this case, we have 6 carbon atoms, 12 hydrogen atoms, and 18 oxygen atoms on the left side (reactants). On the right side (products), we have 6 carbon atoms, 12 hydrogen atoms, and 18 oxygen atoms as well.

To balance the carbons, we place a coefficient of 6 in front of CO2. This gives us 6 carbon atoms on both sides. To balance the hydrogens, we place a coefficient of 6 in front of H2O. This gives us 12 hydrogen atoms on both sides. Finally, to balance the oxygens, we place a coefficient of 6 in front of O2. This gives us 18 oxygen atoms on both sides.

By balancing the equation, we ensure that the law of conservation of mass is obeyed. This means that the total number of atoms of each element remains the same before and after the reaction.

In summary, the balanced chemical equation for the combustion of glucose is:

C6H12O6(s) + 6O2(g) -> 6CO2(g) + 6H2O(g)

This equation shows that when glucose is combusted, it reacts with oxygen to produce carbon dioxide and water.

Monosaccharides may link together to form polysaccharides by forming a glycosidic bond

Simple sugars called monosaccharides can combine to generate polysaccharides through a dehydration reaction. A glycosidic bond, a type of covalent bond, is formed to create this coupling. The hydroxyl group (-OH) of one monosaccharide and the anomeric carbon atom of another monosaccharide combine to form a glycosidic bond.

The characteristics of the resultant polysaccharide depend on the kind of glycosidic bond that forms between the monosaccharides. For instance, the alpha-1,4 glycosidic linkages between the glucose units of a starch molecule, a polysaccharide made of glucose monomers. The molecular structure and properties of cellulose, a distinct polysaccharide made of glucose monomers, are different because of the beta-1,4 glycosidic linkages that connect the glucose units.

The defining feature of the Bohr model of the atom is the concept of quantized energy levels in which electrons can orbit the nucleus.

Bohr proposed that electrons orbit the nucleus in discrete, rather than continuous, energy levels. These levels of energy are quantized, which means they have a fixed value and do not vary continuously.

Bohr also proposed that electrons can move between these energy levels by absorbing or emitting energy, giving rise to the emission and absorption spectra seen in atomic spectra.

The Bohr model was the first successful attempt to describe the structure of an atom, and it helped to lay the groundwork for modern quantum mechanics.

A change in precipitation form

In a reaction sequence involving an alkyne and reagents, step 1) deprotonates the alkyne using a strong base, then forms a new carbon-carbon bond with an electrophilic alkene, and lastly adds an alcohol across the double bond via oxymercuration-demercuration. The major product is an alcohol, but its specific structure depends on the starting materials.

The given reaction sequence involves the following steps:

NaNH₂

Eti H-C=C—H

HgSO₄, H2SO₄, H2O, R-OH

Step 1) involves the treatment of an alkyne with NaNH₂, which is a strong base. The base will deprotonate the alkyne to form an anion.

Step 2) involves the reaction of the alkyne anion with Eti H-C=C—H. The alkyne anion acts as a nucleophile and attacks the electrophilic alkene, forming a new carbon-carbon bond.

Step 3) involves the addition of HgSO₄, H2SO₄, H₂O, and an alcohol (R-OH). This reaction is known as oxymercuration-demercuration and involves the addition of a mercuric acetate (Hg(OAc)₂) across the double bond of the alkene. This forms a mercurinium ion, which is then attacked by water in a nucleophilic addition reaction. Finally, the mercuric acetate is removed by reaction with sodium borohydride, resulting in the formation of the alcohol product.

The major product expected from this reaction sequence is the alcohol formed in step 3). The specific structure of the alcohol cannot be determined without more information about the starting materials.

Explanation:

The correct steps to the following question will be- A magnesium atom donates two electrons to the fluorine atoms → Each fluorine atom accepts one of the electrons → The magnesium atom becomes a +2 ion → Each fluorine atom becomes a -1 ion.

The electronic configuration of fluorine atom is \(1s^2 2s^2 2p^5\)

The electronic configuration of magnesium is  \(1s^2 2s^2 2p^6 3s^2\)

For fluorine to satisfy the requirements of an inert gas configuration, its valence shell needs one electron.

The magnesium, on the other hand, has two electrons in its valence shell. To be stable, it needs an additional six electrons. Due to its electropositive nature, it will give up two of its electrons in order to take on the configuration of the closest inert gas, neon.

Therefore , magnesium will lose two of its valence electrons and becomes a  positively charged cation having +2 charge.

In conclusion, each of the fluorine atoms will accept one electron from magnesium and becomes negatively charged anion having one unit negative charge.

Answer:

72 g/L

Explanation:

The dissolved amount of solute is the difference between the amount you have poured and the amount that precipitated:

125 g - 35 g = 90 g

Thus, 90 grams of solute were dissolved in 1.25 liters. The saturation point is the ratio between the grams dissolved and the volume in liters:

saturation point = 90 g/1.25 L = 72 g/L

The rate t1 shows the beginning of the reaction, the t2 shows an intermediate point in the reaction, and t3 shows almost the end of the reaction.

Reaction rate refers to how fast or slow a chemical reaction is completed. In other words, the velocity at which reactants transform into products.

Aqueous hydrobromic acid HBr will react with solid sodium hydroxide NaOH to produce aqueous sodium bromide NaBr and liquid water H2O. Suppose 3.24 g of hydrobromic acid is mixed with 2.3 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.

HBr(aq) + NaOH (S)-----------> NaBr (aq) + H20

mol wt  of HBr = 1 + 79.9  = 80.9

3,24 gm of HBr = 3.24/80.9 = 0.00400moles = 4.00 X 10^-3 moles

mol wt of NaOH =  23.0 + 16.0 +1.01 = 40.0 gm

2.3 gm = 2.3/40.0 = 0.058 moles =5.8 X 10^-2

the reaction of HBr and NaOH is 1:1.  

there are not enough moles of HBr to neutralize all of the NaOH. so

only 4.00X10 ^-3  moles of H2O can be produced

mol weight of H2O is (2 X 1.01) + 16.0 = 18.0

The maximum mass of H2O that can be produced is

18.0 X 4.00X10^-3 = 72.0/1000 =7.20 X 10^-2 gm
