How many moles of aluminum hydroxide are needed to react completely with 12.3 moles of nitric acid?

Al (OH) 3 + 3HNO3 - 3H2O + Al (NO3) 3

A gas obeys the ideal-gas equation of state P V = N k T, where N = n NA is the number of molecules in the volume V at pressure P and temperature T and n is the number of gm-moles of the gas.

Which of the following choices represents a balanced chemical equation? A. Ca3 (PO4) 2 + 6SiO2 → P4O10 + 3CaSiO3 B. 2Ca3 (PO4) 2 + 6SiO2 → P4O10 + 6CaSiO3 C. 2Ca3 (PO4) 2 + 3SiO2 → 2P4O10 + 2CaSiO3 D. 3Ca3 (PO4) 2 + 2SiO2 → P4O10 + 4CaSiO3
