Based on the Law of Conservation of Mass, what mass of reactants are used during the reaction?

[tex]\[ \text{chlorine gas} + \text{hydrogen gas} \rightarrow \text{hydrogen chloride} \][/tex]

[tex]\[ \text{Mass of Product} = 34.61 \, \text{g} \][/tex]

Give your answer to the correct number of significant figures.

[tex]\[ \text{Mass of Reactants (g)}: \][/tex]



Answer :

To solve this problem based on the Law of Conservation of Mass, we'll consider the principles underlying chemical reactions.

1. Understanding the Law of Conservation of Mass:
The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction. Therefore, the total mass of the reactants before the reaction must equal the total mass of the products after the reaction.

2. Given Reaction:
In this reaction:
[tex]\[\text{chlorine gas} + \text{hydrogen gas} \rightarrow \text{hydrogen chloride}\][/tex]

3. Given Data:
- The mass of hydrogen chloride produced is [tex]\(34.61 \text{ g}\)[/tex].

4. Applying the Law of Conservation of Mass:
- Since the mass of the reactants must equal the mass of the product, the combined mass of the chlorine gas and hydrogen gas (the reactants) must be equal to the mass of hydrogen chloride produced.

5. Calculating the Mass of Reactants:
- The mass of reactants used in the reaction is the same as the mass of the product, which is hydrogen chloride. Therefore, the mass of reactants is [tex]\(34.61 \text{ g}\)[/tex].

6. Final Answer:
Based on the Law of Conservation of Mass, the mass of the reactants used during the reaction is [tex]\(34.61 \text{ g}\)[/tex].

So, the mass of reactants is [tex]\(34.61 \text{ g}\)[/tex].
