What numbers go here? Mg + H2SO4 --> H2 + MgSO4

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?

Freezing 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.

What are the chemical names of these compounds? ke: mg3n2: reset next
