Compare the properties of producer and water gas

producer gas -  

used as cheap fuel in industries

heat treatment for furnaces

alternative to diesel as a fuel

as a fuel to produce hot air in industries

water gas -

for the production of methanol and other hydrocarbons

as fuel gas in industries

as a source of hydrogen

for the manufacturing of ammonia

please note : i am not sure about the answer  so if it is wrong please ignore

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 !
