A typical ice cube has a volume of about 16.0 cm Calculate the amount of energy needed to melt the ice cube. (Density of ice at O. oC = 0.917 g/mL; molar enthalpy of fusion of ice = 6.009 kJ mol; molar mass of H2o = 18.02 g/mol.) a. Determine the mass of the ice cube
b. Determine the number of moles of H20 present in the sample.

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
