Complete the following sentence: When calcium carbonate is heated, the gas is bubbled through limewater using a delivery tube. The delivery tube must be removed from the solution when the heating stops to prevent ______ ; Your answer here;back.

Consider the decomposition of calcium carbonate shown below. Which of the following statements correctly describes this reaction as it occurs in a test tube?CaCO3(s) + 42.5 kcal → CaO(s) + CO2(g)

Consider the decomposition of calcium carbonate shown below. Which of the following statements correctly describes this reaction as it occurs in a test tube? CaCO3(s) + 42.5 kcal → CaO(s) + CO2(g)It is impossible to predict without actually performing the experiment.The test tube would feel warm, since the reaction would release heat to the surroundings.The test tube would feel cold, since the reaction would absorb heat from the surroundings.The test tube would feel warm, since the reaction would absorb heat from the surroundings.The test tube would feel cold, since the reaction would release heat to the surroundings.

Calcium carbonate decomposes on heating. The word equation for this reaction is
