Problem- Calculate the mass of methane that must be burned to provide enough heat to convert 220g of water at 49*C into steam at 107*C (assume that the h20 produced in the combustion reaction is steam rather than liquid water)
Please answer only if you are 100% confident
Consider the following reaction- 2 A(g) + B(g) 3 C(g) + D(g) please determine Kc if 6.0 moles of A is added to 6.0 moles of B in a 2.0 L yields 0.10 moles of D at equilibrium.
