Write the complete balanced equation for the following reaction: na2so4 + pb(no3)2 --> nano3 + pbso4

Explanation:

A reaction equation that shows same number of atoms on both reactant and product sides is known as a balance equation.

Number of atoms on reactant side are as follows.

Na = 2

= 1

Pb = 1

= 2

Number of atoms on product side are as follows.

Na = 1

= 1

Pb = 1

= 1

Therefore, to balance this chemical equation we multiply by 2 on product side. Thus, we can conclude that the balanced chemical equation will be as follows.

"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"
