What does what does c6h12o6+6o2→6co2+6h2o+energy equal to?

The formula of the molecule is C1H6O2, indicating the presence of one carbon atom, six hydrogen atoms, and two oxygen atoms in the molecule.

The formula of the molecule can be determined by listing the number of each type of atom and using their respective symbols.

Number of oxygen atoms = 2

Number of hydrogen atoms = 6

Number of carbon atoms = 1

Since there are two oxygen atoms, we use the subscript "2" for oxygen: O2. Since there are six hydrogen atoms, we use the subscript "6" for hydrogen: H6. Since there is one carbon atom, we don't need to specify a subscript for carbon: C

Using the symbols for each element, we can write the formula of the molecule:

C1H6O2

Therefore, the formula of the molecule comes out to be C1H6O2.

Applied research

Explanation:

The process of developing a new vaccine involves the use of known scientific theories to address specific problems. Here, the outcome of several basic research are put into use to arrive at a targeted outcome. This outcome/product can be continuously modified (if it shows early promise) until the desired effect is achieved and if no "promise" is discovered at critical points of this research, work on this theory (for this research) is suspended another theory is pursued.

This process (described above) in which scientists continuously develop new treatments and/or vaccines and continuously subject it to testing until the desired effect is achieved can be referred to as Applied research.

To determine the states of matter for the conjugate acids, we can consider their common forms when dissolved in water.

F- (aq) -> HF (aq)

Cl- (aq) -> HCl (aq)

NH3 (aq) -> NH4+ (aq)

F- (aq) represents the fluoride ion in aqueous solution. Its conjugate acid is HF (aq), which stands for hydrofluoric acid. When dissolved in water, F- acts as a base and can accept a proton to form HF.

Cl- (aq) represents the chloride ion in aqueous solution. Its conjugate acid is HCl (aq), which stands for hydrochloric acid. When dissolved in water, Cl- acts as a base and can accept a proton to form HCl.

NH3 (aq) represents ammonia in aqueous solution. Its conjugate acid is NH4+ (aq), which stands for ammonium ion. Ammonia acts as a base and can accept a proton to form the ammonium ion, NH4+.

In the electrochemical reaction represented by the balanced equation 3Mn(s) + 2Au₃⁺(aq) → 3Mn₂+(aq) + 2Au(s), a total of 6 moles of electrons are transferred.

The balanced equation provides the stoichiometric coefficients of the reactants and products, which represent the mole ratios in the reaction. In this case, the coefficient of Mn(s) is 3, and the coefficient of Au³⁺(aq) is 2. This means that for every 3 moles of Mn atoms and 2 moles of Au⁺ ions involved in the reaction, 3 moles of Mn²⁺ ions and 2 moles of Au atoms are produced.

Since the balanced equation does not specify the number of electrons involved in the transfer, we need to consider the changes in oxidation states of the elements to determine the number of electrons spectator ions transferred. In this reaction, each Mn atom loses 2 electrons, going from an oxidation state of 0 to +2, while each Au³⁺ ion gains 3 electrons, going from an oxidation state of +3 to 0.

Therefore, for every 3 moles of Mn atoms that lose 2 electrons each and 2 moles of Au³⁺ ions that gain 3 electrons each, a total of 6 moles of electrons are transferred in the reaction.

Explanation:

The equilibrium constant for the reaction is 0.19, which corresponds to option (b).

The equilibrium constant (K) can be calculated using the following formula:

AGº = -RT ln(K)

where R is the gas constant (8.314 J/mol·K), T is the temperature in Kelvin, and ln is the natural logarithm.

First, we need to convert the temperature from Celsius to Kelvin:

T = 25°C + 273.15 = 298.15 K

Now, we can substitute the values into the formula:

4.15 kJ/mol = -(8.314 J/mol·K)(298.15 K) ln(K)

Simplifying:

ln(K) = -4.15 × 10^3 J/mol ÷ (8.314 J/mol·K × 298.15 K) = -1.661

Taking the exponential of both sides:

K = e^(-1.661) = 0.19

Therefore, the equilibrium constant for the reaction is 0.19, which corresponds to option (b).

The statement that is generally true about the rate of decomposition is d) a buried body decomposes more slowly than a body that is not buried.

When a body is buried, it is removed from the natural environment that promotes decomposition, such as exposure to insects and air. Burial slows down the decomposition process and can preserve the body for a longer period of time. Factors such as ambient temperature, water submersion, and weight of the person do affect the rate of decomposition but are not generally true for all cases.

Answer:

The EF of the compound is CH2O and the MF is C6H12O6.

Explanation:

To find the empirical formula (EF) of the compound, we need to determine the simplest whole number ratio of the atoms in the compound. We can assume we have 100 g of the compound, which means we have:

40 g of carbon

6.67 g of hydrogen

53.33 g of oxygen (since the rest of the compound is oxygen)

Next, we can convert the masses to moles:

Moles of carbon = 40 g / 12.01 g/mol = 3.33 mol

Moles of hydrogen = 6.67 g / 1.01 g/mol = 6.61 mol

Moles of oxygen = 53.33 g / 16.00 g/mol = 3.33 mol

We then divide each of the mole values by the smallest number of moles, which is 3.33, to get the simplest whole number ratio:

Carbon: 3.33 / 3.33 = 1

Hydrogen: 6.61 / 3.33 = 1.98 (rounded to 2)

Oxygen: 3.33 / 3.33 = 1

So the EF of the compound is CH2O.

To find the molecular formula (MF), we need to know the molecular mass of the EF. The empirical formula mass (EFM) of CH2O is:

EFM = (1 x 12.01 g/mol) + (2 x 1.01 g/mol) + (1 x 16.00 g/mol) = 30.03 g/mol

We can then calculate the molecular formula mass (MFM) by dividing the given molecular mass (180 g/mol) by the EFM:

MFM = 180 g/mol / 30.03 g/mol = 6

This means the MF is 6 times the EF, or C6H12O6. Therefore

The tiny unit of an element that retains the properties of the element is called an atom.

Atoms are the basic building blocks of matter and are composed of a nucleus, which contains positively charged protons and neutral neutrons, surrounded by negatively charged electrons that orbit the nucleus. The unique arrangement of protons, neutrons, and electrons in an atom determines its chemical and physical properties, such as its atomic number, mass, and reactivity.Atoms are incredibly small and are typically measured in units of picometers or angstroms.

Each element is defined by the number of protons in its atomic nucleus, which is known as its atomic number. For example, carbon atoms have six protons in their nucleus, while oxygen atoms have eight protons. The number of neutrons in an atom's nucleus can vary, resulting in isotopes of the same element with different atomic masses.

Atoms can combine with other atoms to form molecules and compounds through chemical bonds, including covalent bonds, ionic bonds, and metallic bonds.

What is given:

Density of the gasoline = 0.680 g/mL

Mass of the gasoline = 7.20 kg

What to find:

To find how large of a container, (volume) in liters needed to hold the gasoline.

Step-by-step solution:

Step 1: Convert the mass of gasoline from kg to g.

Conversion factor: 1 kg = 1000 g

So 7.20 kg = (7.20 kg/1 kg) x 1000 g = 7200 g

Step 2: Determine the volume in mL using the density equation.

Step 3: Convert the volume in step 2 from mL to liters.

Conversion factor: 1000 mL = 1 L

So, 10588.24 mL = (10588.24 mL/1000 mL) x 1 L = 10.58824 liters

How large of a container, (volume) in liters needed to hold 7.20 kg of gasoline is approximately 10.6 liters

The molality of a 15.0% by mass solution of mgcl2 in h2o is 1.86 m.

Define molality.

The molality of a solution is defined as the number of moles of solute particles present in one kilogram of a solvent. In general, the molality expresses the concentration of a solution. In this case, water acts both as a solute and a solvent.

Given:

Mass solution of MgCl₂ in H₂O= 15%

Density= 1.127g/mL

To find:

Molality=?

Let's solve this question step by step:

Step 1: Calculate the mass of solute and solvent in 100 grams of solution

As it is given that 15.0% by mass solution of MgCl₂ (solute) in H₂O (water).

In 100 g of solution, there are 15.0 g of solute and 100.0 g - 15.0 g = 85.0 g of solvent.

Step 2: Calculate the moles corresponding to 15.0 g of MgCl₂

The molar mass of MgCl₂ is 95.21 g/mol.

Number of moles is given mass divided by the molar mass.

Number of moles= 15g/95.21 g/mol

=0.158 mol

Step 3: Convert the mass of water to kilograms.

As we know, 1 kg = 1,000 g.

=85/1000= 0.085 kg

Step 4: Calculate the molality of the solution.

Molality is a measure of the number of moles of solute in a solution corresponding to 1 kg or 1000 g of solvent.

Molality= 0.158 mol/0.085 kg

= 1.86 m.

Therefore, the molality of a 15.0% by mass solution of mgcl2 in h2o is 1.86 m.
