Balance each of the following chemical equations. (Use the lowest possible coefficients for all reactions.) a. b. c. d. e. f. g.

The question is in complete, complete question is :

Balance each of the following chemical equations. (Use the lowest possible coefficients for all reactions.

a)

b)

c)

d)

e)

Explanation:

Law of conservation of mass 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 or total number of all atoms of each elements on reactant sides are equal to the total number of all atoms of each element on product side

a)

b)

c)

d)

e)

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
