PLEASE I NEED HELP how many moles of calcium are needed to react completely with 6 moles of H2O in the following reaction:
Ca + 2H2O = Ca(OH)2 + H2 (make sure to include work)

Given the following information: mass of proton = 1.00728 amu mass of neutron = 1.00866 amu mass of electron = 5.486 × 10^-4 amu speed of light = 2.9979 × 10^8 m/s calculate the nuclear binding energy (absolute value) of 3li^6. which has an atomic mass of 6.015126 amu. j/mol.

The term gas is limited to those substances that exist in the gaseous state at
