Answer:

4FeS + 7O₂ ----> 2Fe₂O₃ + 4SO₂

Explanation:

You have to drag the elements shown on the right under the formula.  For example, you would have to drag 4 of the FeS molecules under the 4FeS text in the formula.  Then place 7 O₂ molecules under the 7O₂ text, etc.

Such prefixes as this are expressed in the order of tens. Units generally exists scientifically in multiples and submultiples form using prefixes.

For the multiples:

             10                            deca(da)

            100                           hecto(h)

            1000                        kilo(k)

         1000000                    mega(M)

Which describes why the magma moves in the direction of
kenny6666 [7]

The magma is heated and becomes less dense by the core moving it toward the crust.

Explanation:

Magma is a molten or partially molten rock form. Magma consists of silicate liquid, although carbonate and sulfide melts occur as well. It moves either to depth or to Earth’s surface and is ejected as lava. Suspended crystals and fragments of un-melted rock get transported in the magma dissolved volatiles may separate as bubbles and some liquid get crystallize during movement.

Several interrelated physical properties determine the characteristics of magma, including chemical composition, viscosity, dissolved gases, and temperature.Magma also form igneous rock.

Therefore the magma is heated and becomes less dense by the core moving it toward the crust.
