The number of molecules contained in a 4.30-g sample of dimethylmercury is 1.12 × 10²² molecules.

The number of molecules of a substance can be calculated by multiplying the number of moles in the substance by Avogadro's number as follows:

no of molecules = no of moles × 6.02 × 10²³

According to this question, 4.30-g sample of dimethylmercury (C₂H₆Hg) is given. The molar mass of C₂H₆Hg is 230.659 g/mol.

no of moles of dimethyl mercury = 4.3g ÷ 230.659 g/mol = 0.0186 moles

no of molecules of dimethyl mercury = 0.0186 moles × 6.02 × 10²³

no of molecules = 1.12 × 10²² molecules

Therefore, the number of molecules in 4.3g of C₂H₆Hg is calculated to be 1.12 × 10²² molecules.

The balanced chemical equation of reaction is -

2 Na(s) + 2 HCl(aq)  ⟶  2 NaCl(aq) + H₂(g)

We know that,

weight of sodium metal is 0.384 g

Molar mass of Na is 23 g/mol

we will calculate the number of moles,

Number of moles = Given mass

                                 Molar mass

Moles of Na =  0.348 g   = 0.015 mol

                        23 g/mol

We will calculate the energy in 1 mole of sodium metal

In 0.015 moles of sodium metal, 3990 J of energy is produced.

so, in 1 mole of sodium metal, 3990 J of energy is produced

Step 1 -

A decomposition reaction is a reaction in which a compound is decomposed, i.e., we usually heat a substance thus forming new substances, such as gaseous substances.

Generally speaking, a decomposition reaction will involve only one reactant: the substance to be decomposed.

Step 2 - Examples of decomposition reactions

Let's take a closer look at some examples:

We can already state some conclusions:

a) The products are not always the same. They depend on the reactant. Therefore, they are not always predictable.

b) The reactant can be an ionic compound (such as ZnCO3) but also a covalent compound (such as H2CO3).

c) The reactant does not decompose into its constituent elements.

Step 3 - Finding the wrong answer

Therefore, the only wrong answer is item b), the products are the constituent elements.

The percent yield of the reaction is calculated as follows:

Percent yield = actual yield/ theoretical yield * 100 %

The percent yield of the reaction is less than 100%.

The percent yield of a reaction is the ratio of the actual yield of a reaction and the theoretical yield of the reaction.

Mathematically:

The percent yield of any reaction is never 100& percent because no reaction actually goes to completion forming exactly all the product that is expected.

Considering the give reaction of the formation of nitric acid in the atmosphere:

The equation of the reaction is:

4 NO (g) + 3 O₂ (g) + 2 H₂0 (g) ---> 4 HNO₃ + excess oxygen.

The percent yield will require the actual yield and the theoretical yield in order to be calculated.

For example, if the actual yield is 12 g and the theoretical yield is 15 g, percent yield = 12/15 * 100%

Percent yield = 80%

Temperature is the degree of hotness or coldness of an object

Here given data is certain reaction has an activation energy of 36.11 kJ/mol and reaction proceed 4.50 times faster than it did at 315 K and we have to find kelvin temperature = ?

Then, we have to use the arrhenius equation and set k1 = 1 and k2 = 4.50 because rate = k[A] so as long as concentration of reactants doesn't vary, rate is proportional to k

ln (k₂/k₁) = Ea/R(1/T₁ - 1/T₂)

k₂ = 4.50

k₁ = 1

Ea = 36.11 J/mole

R = 8.314 J/mol⁻k

T ₁= 315 K

T₂ = ?

ln(4.50/1) = 36.11/8.314 (1/314 - 1/T₂)
