2. Jazmin and Ty did a chemistry experiment in which they dissolved the ionic compound lithium chloride (LICI) in water. They observed that after mixing 3.0 g of the ionic compound into 20 mL of water, the temperature dropped from 22 °C to 15 °C. Based on these experimental results, it is likely that all of the following would result in a greater temperature decrease except: a. Using 6.0 g of LiCl and 20 mL of water
