Explanation:
Endo means inside
but exo means outside
an Endo thermic reaction sounds like it wouldn't be the one to give off heat, so it might be storing heat.
To balance it, it would be N2 + 3H2 ------> 2NH3.
for c) it would be 2N2 + 6H2 -------> 4NH3
Volume = 20.0 cm³
density = 19.3 g/cm³
Therefore:
mass = density * volume
mass = 19.3 * 20.0
mass = 386 g
