Hi, I'd appreciate some help
Which is the correct equation to calculate the energy needed to heat steam from 105 ˚C to 115˚C?

q=m∆Hf
q=m∆Hfv
none of these
q=mC∆T

Thank you! :)

Calcium hydride (cah2) reacts with water to form hydrogen gas: cah2(s) + 2h2o(l) → ca(oh)2(aq) + 2h2(g) how many grams of cah2 are needed to generate 45.0 l of h2 gas at a pressure of 0.995 atm and a temperature of 32 °c?
