Tell me if these are right
24. earth's rigid out layer, consisting of the crust and uppermost mantle, is called the {"(lithosphere)"}
25. the type of plate boundary where plates move apart, resulting in upwelling of material from the mantle to create new seafloor, is referred to as a(n) {"(divergent)"} plate boundary.
26 the primary forces that cause plate motion are made possible by a mechanism called {"(centrifugal effects)"}l me if these are right

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 !

lol for the pointsss

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
