Breaking down by heating 4 of 8 Name the products formed when calcium carbonate is heated strongly Calcium oxide and carbon dioxide 5 of 8 wha is the word equation for the reaction of calcium oxide with water? calcium oxide + water > calciun hydroxide 6 of 8 Limewater goes cloudy when mixed with carbon dioxide, explain why Calcium carbonate is formed and is insoulbe 7 of 8 Why do acids damage limestone? acids react with calcium carbonate, producing carbon dioxide and a salt. The salt dissolves in the water so the amount of limestone deacreases 8 of 8
