An IPS student performs experiment 6.4 and finds the following data: Massof Zinc (before dissolving) = 2.4g
Massof Zinc (after dissolving) = 1.2g
Mass of empty evaporating dish =
31.0 g
Mass of evaporating dish and Zinc Chloride = 33.4 g
1. What mass of zinc reacted (dissolved) with the acid?

Summarize possible ways in which phases of matter could combine to form a solution.

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
