Science! What type of heat transfer takes place when a furnace heats up an entire room?

Radiation, because the element of the heater comes in contact with air in the room

Convection, because energy is carried by waves and not matter

Radiation, because heat travels in a cyclical manner

Convection, because air currents are formed

Radiation, because the element of the heater comes in contact with air in the room. Convection, because energy is carried by waves and not matter. Radiation, because heat travels in a cyclical manner.

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 !

- lead + phosphoric acid = hydrogen + lead(ii) phosphate
