O2 and NH3 can react according to the equation: 3O2+4NH3=2N2+6H2O A) what is the limiting reactant if 98g of 21% pure oxygen and 26g of ammonia are used
B) what mass of water can theoretically form
C) If 15g of water is the actual yield, what is the percent yield

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the boiling of water, and explain your predictions. how does temperature affect the spontaneity of this process?

Which compound contain an iron with a 3+ charge

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
