Potassium superoxide, KO2, reacts with carbon dioxide to form potassium carbonate and oxygen:
This reaction makes potassium superoxide useful in a self-contained breathing apparatus. How much O2 could be produced from the reaction of 4.88g of KO2 with 2.56g of CO2?
Since you have asked multiple questions, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question
When NaHCO3 is heated, it decomposes to form sodium carbonate, water, and carbon dioxide.
The balanced chemical equation can be written as follows:
2NaHCO3 → Na2CO3 + H2O + CO2
2 mol 1 mol 1 mol 1 mol
According to the balanced equation:
2 mol of NaHCO3 produces 1 mol H2O.
