Please give answer andexplanation !
Consider the following reaction: CH4 (g) + 2O2 (g)----------}CO2(g) + 2H20(g) ^Hr= -890 kj
a) is heat absorbed or evolved in the course of thereaction?
b) Calculate the amount of heat trasnferred when 45g of CH4 isdecomposed by this reaction at constant pressure.
c) For the given sample of CH4 the enthalpy change on reactionis 66.8 kj. How many grams of H2O are produced?
d) what is the value of ^Hr for the reverse of the previousreaction? How many KJ of heat are released when 27g of H2O reactscompletely with CO2to form CH4 and O2 at constant pressure?
