Mammals that live in the arctic ocean have a large amount of blubber, which is a fatty tissue just beneath the skin. which statement best relates why these animals have so much blubber?
lipids in blubber insulate the animals from cold water.
proteins in blubber the animals move to stay warm.
carbohydrates in blubber provide all the energy that the animals need to stay warm.
nucleic acids build the lipids in blubber, which keep animals warm by regulating cell activities.

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 !
