Click on the hess's law of constant heat summation button within the activity and use the example shown to calculate the reaction enthalpy, δh, for the following reaction: ch4(g)+2o2(g)→co2(g)+2h2o(l)use the series of reactions that follow: c(s)+2h2(g)→ch4(g), δh =−74.8 kj. c(s)+o2(g)→co2(g), δh =−393.5 kj. 2h2(g)+o2(g)→2h2o(g), δh =−484.0 kj. h2o(l)→h2o(g), δh =44.0 kj.
