1. if you have used 100 mL of water and 15.0 g of NH4Cl in the experiment instead of 80.0 mL of water and 12.0 g of NH4Cl, to determine change of heat solution, would you expect to get a larger, smaller, or identical temperature change? why?

2. why is the dissolving of ammonium chloride endothermic? Would you get similar results for dissolving all salts? Explain the answer using another salt as an example.
