C(s) + O2(g) → CO2(g)
CaO(s) + H2O(l) → Ca(OH)2(s)
C(s) + H2O(g) → CO(g) + H2(g)
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)

Water Gas is a mixture of carbon monoxide and hydrogen produced from synthesis gas.\(H_2O + C --> H_2 + CO\) (H=+131KJ/mol)
An Endothermic process is any process which requires or absorbs thermal energy from its surroundings, usually in the form of heat.in Endothermic reaction ∆H is positive.
Therefore it is Endothermic
