The balanced thermochemical equation for the decomposition of methanol (CH3OH(g)) to form CH4(g) and O2(g) can be written as:

CH3OH(g) -> CH4(g) + O2(g) + 252.8 kJ/mol of O2 formed.

To find the number of moles of MgCl₂ in 41.5 g, you divide the mass of the substance by its molar mass. The molar mass of MgCl₂ is 95.21 g/mol, resulting in 0.436 moles of MgCl₂.

To calculate the number of moles of MgCl₂ in 41.5 g, you need to know the molar mass of MgCl₂.

The molar mass is the sum of the mass of one mole of magnesium (Mg) ions and two moles of chloride (Cl) ions.

The molar mass of Mg is 24.305 g/mol and the molar mass of Cl is 35.45 g/mol.

Therefore, the molar mass of MgCl₂ is (1 × 24.305) + (2 × 35.45) = 95.21 g/mol.

Next, use the formula: Number of moles = Mass of substance (g) / Molar mass (g/mol)

Number of moles of MgCl₂ = 41.5 g / 95.21 g/mol = 0.436 moles of MgCl₂.

The volume of 32.7 grams of water vapor at standard temperature and pressure can be calculated by first finding the number of moles and then using the Ideal Gas Law.

To solve this problem, we need to use the Ideal Gas Law, which is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. Firstly, we calculate the number of moles of the water vapor. Since the molecular weight of water (H2O) is approximately 18 g/mol, 32.7 grams is about 32.7/18 = 1.817 moles. The value of R in liter·kPa/K·mol is 8.314. The temperature T is given in the problem as 273 K.

Now we can put all these values into the Ideal Gas Law:

100 kPa * V = 1.817 mol * 8.314 kPa L−1 K−1mol−1 * 273 K

Solving the above equation for V would give us the volume in liters of the water vapor under the given conditions.

32.7 grams of water vapor occupies 41.1 liters at standard temperature and pressure (273 K and 100 kPa).

To determine the volume of 32.7 grams of water vapor at standard temperature and pressure (273 K and 100 kPa), we use the ideal gas law, PV = nRT. First, we need to convert the mass of water (H₂O) into moles:

Next, we plug this value into the ideal gas law formula. Given that P = 100 kPa, V is what we need to find, n = 1.814 moles, R (ideal gas constant) = 8.314 J/(mol·K), and T = 273 K:

V = nRT / P
V = (1.814 moles) × (8.314 J/(mol·K)) × (273 K) / (100 kPa)
Since 100 kPa = 100,000 Pa (because 1 kPa = 1000 Pa):

Therefore, at standard temperature and pressure, 32.7 grams of water vapor occupies 41.1 liters.

Answer:  High Reactivity

Explanation:  Alkali metals are the metals which are kept in the group 1 which is also known as S -Block elements.

The electronic configuration of the elements can be written as ns1 .

These are considered to be the most reactive elements of the whole periodic table because their outermost shell has only 1 vacant electron and thus are in need of only 1 electron to complete its duplet or either they can also lose that  one electron .

This the reason they can never be found pure in the nature .

Answer: Option (D) is the correct answer.

Explanation:

When there is minimum use of energy and we are still able to preserve resources then it means we are cutting the demand for energy.

Therefore, when we are treating water with chlorine then it means without any electricity or energy we are cleaning the water. But at the same time chlorinated water is harmful to use unless chlorine is dissolved in limiting quantity.

Whereas energy efficient appliances will use the electricity efficiently.

Landfill will require the use of machines or man power therefore, energy will be used.

On the other hand, when rules are framed against the use of chlorofluorocarbons then there will be lesser depletion of ozone layer. Hence, use of energy will be minimum.

Thus, we can conclude that legislation against the use of chlorofluorocarbons has helped preserve resources while cutting the demand for energy.

The balanced nuclear equation for the beta decay of carbon-11 is ⁶₁₁C → ⁶₁₂N + ⁰⁻₁e, which indicates carbon-11 transforming into nitrogen-11 and emitting a beta particle (electron).

The beta decay of carbon-11 is a type of radioactive decay where a beta particle (an electron) is emitted from an atomic nucleus. Writing a balanced nuclear equation for this process involves showing the original nucleus, the emitted beta particle, and the resulting daughter nucleus. In beta decay, a neutron in the nucleus is transformed into a proton and an electron. The electron is ejected from the nucleus as the beta particle, and the atomic number of the nucleus increases by one while the mass number remains the same.

The balanced nuclear equation for the beta decay of carbon-11 is:

⁶₁₁C → ⁶₁₂N + ⁰⁻₁e

Here, carbon-11 (⁶₁₁C), with 6 protons and 5 neutrons, decays to nitrogen-11 (⁶₁₂N), which has 7 protons and 4 neutrons, by emitting a beta particle (⁰⁻₁e, also represented as β-). This process increases the atomic number by one, from carbon (6) to nitrogen (7), while the mass number remains 11.

Final answer:

The balanced nuclear equation for the beta decay of carbon-11 is 11C → 11B + β + γ. The daughter isotope in this decay is boron-11 (11B).

Explanation:

The balanced nuclear equation for the beta decay of carbon-11 is:

11C → 11B + β + γ

The daughter isotope in this decay is boron-11 (11B).

To find the density of a liquid with a mass of 22.00 grams and a volume of 10.0 ml, divide the mass by the volume to get a density of 2.20 g/ml.

To calculate the density of a liquid, you can use the formula:

Density = mass / volume

In this case, the mass of the liquid is 22.00 grams and the volume is 10.0 ml (which can also be written as 10.0 cm³ as 1 ml is equivalent to 1 cm³). Plugging these values into the formula gives us:

Density = 22.00 g / 10.0 ml = 2.20 g/ml

Therefore, the density of the liquid is 2.20 g/ml.

To determine the pH of a solution which has 0.06 m in sodium benzoate (nac7h5o2) and 0.09 m in benzoic acid (hc7h5o2), we use the ICE table and the acid dissociation constant of hc7h5o2 to determine the concentration of the hydrogen ion present at equilibrium. We do as follows:

HC7H5O2 = H+ + C7H5O2-
NaC7H5O2 = Na+ + C7H5O2-

Therefore, the only source of hydrogen ion would be the acid. We use the ICE table,
                   HC7H5O2           H+        C7H5O2-
I                     0.09                  0              0.06
C                      -x                    +x               +x
------------------------------------------------------------------
E                 0.09-x                x              0.06+ x

Ka = 6.28x10^(-5) = (0.06 + x) (x) / 0.09 -x 
x = 9.40x10^-5 M = [H+]

pH = - log [H+] 
pH = -log  9.40x10^-5 M
pH = 4.03

Therefore, the pH of the resulting solution would be 4.03.

Explanation:

To answer this problem, let us first define what a buffer solution is.

A buffer solution by definition is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or a weak base and its conjugate acid.

In this case, we have are going to have a mixture of a weak acid and its conjugate base. Sodium Formate or HCOONa is the conjugate base of that weak acid. Sodium formate is properly written as:

HCOO-Na+

We can find the weak acid by replacing Na+ with H+. Therefore, the other substance should be:

HCOO-H+

or

HCOOH

Answer:

Formic Acid = HCOOH

Answer:

3 moles of HClO₄ is required to neutralize 1 mole Al(OH)₃.

Explanation:

The neutralization reaction between HClO₄and Al(OH)₃is as follows:

HClO₄ + Al(OH)₃ -> Al(ClO₄)₃ + H₂O

The balanced reaction is as follows:

3HClO₄ + Al(OH)₃ -> Al(ClO₄)₃ + 3H₂O

Based on the balanced molecular equation the molar ratio of HClO₄ : Al(OH)₃ is 3:1.  

So 3 moles of HClO₄ is required to neutralize 1 mole Al(OH)₃.  

Explanation:

Molality is defined as the number of moles of solute per kg of solution. That is, molality depends on the mass.  

Whereas molarity is defined as the number of moles per liter of solution. That is, molarity depends on the volume of solution.

Also, when there is change in temperature then volume of solution changes but mass does not change.

Thus we can conclude that investigating changes in colligative properties involves the measurement of a solution's concentration in molality instead of molarity because mass does not change whereas volume does change.
