8. Here's another calorimetry problem to solve: A solid s cs ubstance with a mass of ty 200g is at its melting
point temperature in a calorimeter. While the substance changes from a solid to a liquid at the same
temperature, the 400g mass of water in the calorimeter goes from an initial temperature of 80°C to a
final temperature of 30°C. (a) How much heat did the water lose while the substance melted? (b)
What is the heat of fusion of the substance that melted?

Look at the reaction below: ca(hco3)2 --> caco3 + co2 + h2o first, balance the reaction. once balanced, use dimensional analysis or another method to find out how many moles of carbon dioxide will be produced if we start with 16.5 moles of calcium bicarbonate (calcium hydrogen carbonate). = mol of co2 number needs to be reported to three significant figures.
