How many moles of lead would have been melted, if you lost 13,000 J of energy? (Heat of fusion = 162 J/g)

If a reaction has g of -136kj at 110°c, will it be spontaneous at this temperature (110°c)? yes or no

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

Avariable that is not being directly tested during an experiment should be
