Pour the water from part B into one of the large containers. Pour the vinegar into the other large container. Observe the two combinations. Pick up each container one at a time and place your palm on the bottom to see whether you can feel a difference in temperature. Record what you see and feel.

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 !
