Answer:

Q=210.8kJ

Explanation:

Hello!

In this case, since the heat of vaporization is related with the energy required by a substance to undergo the phase transition from liquid to gas, we can compute such amount of energy as shown below:

Q=m\Delta H_{vap}

In such a way, since the enthalpy of vaporization is given as well as the mass, we compute the energy as shown below:

Q=155g*1360J/g\\\\Q=210.8kJ

Best regards!

MaRussiya [10]
Answer:
46.3g H2O

Explanation:
start by balancing it: CaC2(s) + 2H2O(g) -> Ca(OH)2(s) + C2H2(g)

then use factor label method to solve

82.4g CaC2 x (1 mol CaC2/64.10g CaC2) x (2 mol H2O/1 mol CaC2) x (18.016g H2O/1 mol H20) = 46.3g H2O
