1. Diazomethane has the following composition by mass: 28.57% C, 4.80%H, and 66.64% N. The molar mass of diazomethane is 42.04 g/mol. Find the molecular formula and draw it's Lewis Structure.
2. An ice cube at 0.00 degrees C with a mass of 23.5 g is placed into 550.0g of water, initially at 28.0 degrees C, in an insulated container. Assuming that no heat is lost to the surroundings, what is the temperature of the entire water sample after all of the ice has melted?
