The mixture was stirred until all of theNaHCO3 dissolved. 3.5 g of solid NaHCO3 was added to 50.0 g of water in a calorimeter. The temperature of the water changed from 20.1*C to 16.7*C.
1. Explain is the reaction exothermic or endothermic?
2. Write down the balanced net ionic equation for the dissolution of NaHCO3.
3. Determine the amount of heat flow of the water?
4. Estimate the heat flow due to the solution process?
