Uses for Sodium Percarbonate Around the Home

Write the balanced chemical reaction, including phase labels, for this reaction:"solid sodium bicarbonate decomposes into solid sodium carbonate, gaseous carbon dioxide, and liquid water."

SOLVED: Question 30 (2.5 points) Consider the reaction where potassium carbonate reacts with nitric acid: K2CO3(aq) 2 HNO3(aq) -> 2KNO3(aq) H2O(l) CO2(g) Calculate the mass of carbon dioxide gas produced if 10.901g of K2CO3 reacts with 13.39mL of 1.76M HNO3.

Reaction of Br2 with Na2CO3 in aqueous solution gives sodium bromide and sodium bromate with evolution of CO2 gas. The number of sodium bromide molecules involved in the balanced chemical equation is:
