Answer:
I HOPE IT HELPS YOU!
Explanation:
•When 4.90 grams of potassium chlorate (KClO3) is heated, it decomposes to form potassium chloride (KCl), oxygen (O2), and some residue.
•According to the law of conservation of mass, the mass of the reactants must be equal to the mass of the products 1234.
Given that 1.92 grams of oxygen and 2.96 grams of residue were produced, we can calculate the mass of potassium chloride produced as follows:
Mass of KCl = Total mass of products - Mass of O2 - Mass of residue
= 4.90 g - 1.92 g - 2.96 g
= 0.02 g
Therefore, the mass of potassium chloride produced is 0.02 grams.
