Yuliya22 [10]

We produce formaldehyde for medicinal purposes and synthesizing polyester.

Formaldehyde is a compound that is required in about 1.5 ounces in quantity as a normal part of our metabolism.

Also formaldehyde is used as a catalyst in the formation for the synthesis of many polyesters.

Formaldehyde also has many uses such as fungicide, germicide, disinfectant and as a preservative in mortuaries as well as important chemical in medical Laboratories.

In everyday items press fabric paints coating and paper base products also includes formaldehyde.

A reaction generates hydrogen gas (H) as a product. The re-

Amiraneli [1.4K]

<u>Answer:</u> The average rate of the reaction is $7.82\times 10^{-3}M/min$

<u>Explanation:</u>

To calculate the molarity of hydrogen gas generated, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}$

Moles of hydrogen gas = $3.91\times 10^{-2}mol$

Volume of solution = 250 mL = 0.250 L (Conversion factor: 1 L = 1000 mL)

Putting values in above equation, we get:

$\text{Molarity of }H_2=\frac{3.91\times 10^{-2}mol}{0.250L}=0.1564M$

Average rate of the reaction is defined as the ratio of concentration of hydrogen generated to the time taken.

To calculate the average rate of the reaction, we use the equation:

$\text{Average rate of the reaction}=\frac{\text{Concentration of hydrogen generated}}{\text{Time taken}}$

We are given:

Concentration of hydrogen generated = 0.1564 M

Time taken = 20.0 minutes

Putting values in above equation, we get:

$\text{Average rate of the reaction}=\frac{0.1564M}{20.0min}\\\\\text{Average rate of the reaction}=7.82\times 10^{-3}M/min$

Hence, the average rate of the reaction is $7.82\times 10^{-3}M/min$
