When the following equation is balanced, the coefficient of al is al (s) + h20 (1) - al(oh)3 (s) + h2 (g) a) 4 b) 1 c) 5 d) 3 e) 2

The correct answer is Option E.

Explanation:

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.  

This also means that total mass on the reactant side must be equal to the total mass on the product side.

The balanced chemical equation for the reaction of aluminium and water follows:

The coefficient of Aluminium is 2.

Hence, the correct answer is Option E.

a is the answer to this question

explanation:

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
