two shopping carts are pushed on a road. the shopping carts have the same mass. shopping cart a is pushed with three time the force as shopping cart b. how does the force applied to the shopping carts affect there acceleration?

shopping cart A will accelerate three times faster than shopping cart B

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 !
