The provided balanced equation applies to the reaction that takes place between lithium hydroxide and sulfuric acid. 2LIOH + H250,-LI SO, + 2H2O
If the reaction begins with 26.7 grams of lithium hydroxide (LIOH) and 164.08 grams of sulfuric
acid (H, SO.), how many grams of lithium sulfate (Li, SO) is produced? Assume 100% yield.
Round your answer to the nearest tenth of a gram.

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 !
