*20 POINTS* PLZ HELP: How is matter conserved during the carbon cycle? In your answer be sure to mention how carbon moves from the atmosphere into earth/ocean through plants and animals. Also, be sure to mention how carbon is released back into the atmosphere. Does the amount of carbon ever change as it moves from one place to another? Your response should be 5-7 sentences.

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 !
