Question

if the mass of the products is 20 grams then the mass of the reactants is

Answer 1

In chemical processes, no mass is generated nor eliminated. In other words, the mass of the reactants and products must be equal. So, if we apply this law to this situation, we will receive a result.

The Law of Conservation of Mass was established in 1789 by Antoine Lavoisier, who discovered that;

In chemical processes, no mass is generated nor eliminated. In other words, the mass of the reactants and products must be equal.

So, if we apply this law to this situation, we will receive a result.

If 'x' is assumed to be the remaining mass,

The mass of the reactant equals the mass of the result.

56+x=100

x=100–56

x=44 g

As a result, the reactant's remaining mass is '44 g'.

Answer 2

• The mass of the reactants and the mass of the products are equal.
• During a chemical reaction, the total mass of the products must match the total mass of the reactants, according to the law of conservation of mass.
• In a chemical reaction, the total mass of reactants equals the total mass of products, according to the law of conservation of mass.
• The mass of sodium plus the mass of chlorine that interacts with the sodium, for example, equals the mass of sodium chloride as a product.
• By using this law, if the mass of product is $20$ then, the mass of the reactants is $44$ grams.
