Question

a student performed a chemical reaction in which 46 grams of sodium(Na) and 71 grams of chlorine (Cl) were combined to form table salt and heat. If the Law of Conservation of Mass is correct, What is the mass of the products?

Answer 1

Answer:

$\boxed {\boxed {\sf 117 \ grams}}$

Explanation:

The Law of Conservation of Mass states that mass can't be created or destroyed.

In terms of a chemical reaction, the reactants' mass must equal the products' mass.

In this reaction, the reactants (substances that undergo the change) are sodium and chlorine.

Let's find the mass of the sodium and chlorine.

• The mass of the sodium is 46 grams and the chlorine mass is 71 grams.
• Add the two masses together
• 46 g + 71 g= 117 g

The mass of the reactants is 117 grams, so the mass of the products of table salt and heat is also 117 grams.
