Solution: In a combustion reaction, 46.0 g of ethanol reacts with 96.0 g of oxygen to produce water and carbon dioxide. If 54.0 g of water is produced, what mass of carbon dioxide is produced?

Problem

In a combustion reaction, 46.0 g of ethanol reacts with 96.0 g of oxygen to produce water and carbon dioxide. If 54.0 g of water is produced, what mass of carbon dioxide is produced?

Solution

Modern Atomic Theory states that matter is composed of small, indivisible particles called atoms. 


The Law of Conservation of Mass states that matter can neither be created nor destroyed, all that happens is that it changes forms. 


Law of Definite Proportions states that all samples of a compound, no matter on their origin or preparation has the same ratio in terms of their elements.


Law of Multiple Proportions states that when two elements (A & B) form different compounds the mass of element B that combine with 1 g of element A are a ratio whole numbers.
