Question

In a chemical reaction, the mass of product is 56g. One of the reactant has a mass equal
to 26g, what will be the mass of other reactant. Which law is governed in this situation?
Who proposed the law? State the law.

Answer 1

❤️Answer❤️

The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that;

Mass is neither created nor destroyed in chemical reactions. In other words,the mass of the reactants must equal the mass of the products.

So, if we apply this law here we will get answer.

If we suppose ‘x’ remaining mass then,

Mass of reactant=Mass of product

56+x=100

x=100–56

x=44 g

So, the remaining mass of reactant is ’44 g’.

Explanation:

law of conservation of mass

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

Answer 2

The mass of another reactant is 30g and it is following the law of conservation of mass.

Given:

In a chemical reaction, the mass of the product is 56g. One of the reactants has a mass equal

to 26g.

To Find:

The mass of another reactant.

Solution:

To find the mass of another reactant we will follow the following steps:

As we know:

According to the law of conservation of mass in a chemical reaction total mass of the reaction remains constant and it is constant even at any instant of the reaction.

So,

Mass of the reactants = mass of the products

A + B → C

Mass of one of the reactants = 26g

Mass of product = 56g

Mass of another reactant = Mass of product - a mass of one reactant = 56-26 = 30g

Henceforth, the mass of another reactant is 30g and it is following the law of conservation of mass.
