Question

if 12 grams of carbon react completely with 20 grams of oxygen in a sealed container, what can be concluded about the mass of the products formed?
the total mass of the products will be more than 32 grams.
the total mass of the products will be less than 32 grams.
the total mass of the products will be 32 grams.
the mass of the products cannot be determined.

Explanation:

Step1: Apply the law of conservation of mass

The law of conservation of mass states that in a chemical reaction, the total mass of the reactants is equal to the total mass of the products.

Step2: Calculate the total mass of reactants

The mass of carbon is \(12\) grams and the mass of oxygen is \(20\) grams. So the total mass of reactants is \(12 + 20=32\) grams.

Answer:

The total mass of the products will be \(32\) grams.
