balance the following reaction. a coefficient of "1" is understood. choose option "blank" for the correct answer if the coefficient is "1."
c4h10 + o2 → co2 + h2o

Answer;

The balanced equation will be;

2C4H10 + 13O2 -> 8CO2 + 10H2O

Explanation;

-According to the law of conservation of mass , in each chemical equation the mass should be conserved, therefore the number of atoms of each element should be equal on the side of reactants and that of products, this is done by balancing the chemical equation.

-Therefore, to balance the above chemical equation, we will put a coefficient of 2 on C4H10, a coefficient of 13 on O2, a coefficient of 8 on CO2 and a coefficient of 10 on H2O. By so doing the equation will be balanced since the number of atoms of each element are equal on either side. We obtain;

2C4H10 + 13O2 -> 8CO2 + 10H2O

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
