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

Calcium carbonate (CaCO3) is a common substance found in rocks. When it's heated, it breaks down to form a new solid, calcium oxide (CaO). This reaction releases carbon dioxide gas (CO2).Determine the symbol equation for this reaction, including state symbols.Note: You can copy and paste this arrow: →

Solid calcium carbonate (CaCO3) reacts with sulfuric acid (H2SO4), which is an aqueous solution. The reaction has three products: solid calcium sulfate (CaSO4), liquid water and carbon dioxide gas.Describe the chemical reaction using both a word equation and a symbol equation.Note: You can copy and paste this arrow: →

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.

100 g of calcium carbonate was heated until it decomposed to give calcium oxide and carbon dioxide. 56 g of calcium oxide was left. Work out the mass of carbon dioxide given off.
