Which types of energy transformations does a television make? Electrical energy to energy of motion and heat energy
Electrical energy to heat energy and light energy
Electrical energy to sound energy and energy of motion
Electrical energy to sound energy and light energy

d.

Explanation:

the electricity is why we can hear sounds from the television and see it

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 !
