Question

observe the burning candle. what can be said about the mass of the products of the completely burned candle compared to the mass of the brand new candle (the reactants) before it was burned? the mass of the new candle is the same as the mass of the burnt candle plus all of the products. the mass of the new candle is greater than the mass of the products. the mass of the new candle is less than the mass of the products.

Explanation:

According to the law of conservation of mass, in a chemical reaction (such as candle - burning), the total mass of reactants is equal to the total mass of products. The mass of the un - burned candle (reactant) is equal to the mass of the remaining burned - out part of the candle plus the mass of all the gaseous and solid products formed during burning.

Answer:

The mass of the new candle is THE SAME AS the mass of the burnt candle plus ALL of the products.
