1. which of the following is a correctly written thermochemical equation?
nh4cl nh4+ + cl
2c8h18 + 25o2 16co2 + 18h2o, h = 5,471 kj/mol
fe (s) + o2 (g) fe2o3 (s), h = 3,926 kj
--> c3h8 (g) + 5o2 (g) 3co2 (g) + 4h2o (l), h = 2,220 kj/mol
2. how does a phase change affect a thermochemical equation?
it alters the moles of reactants.
--> it can affect the (delta) h value.
it alters the products.
it affects the balance of the equation.
