Assuming room temperature is greater than temperature of ice water, (SELECT ALL OF THE FOLLOWING THAT ARE CORRECT) A. Heat flows from the ice cubes into the water B. Heat flows from the water into the ice cubes C. Heat flows from the cup into the room air D. Heat from the air in the room flows into the cup E. There is no heat flow between the ice cubes and the water because they are equilibrium

output?

explanation:

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 !
