2Mg+ O₂= 2MgO
The charge of Mg is+2 and the charge of Oxygen is -2. 2 oxygen atoms will have a charge of -4 so the Mg atoms have to equal +4. A coefficient of 2 for the Mg atoms will balance it out

The correct choice is e. Two of the above.
Explanation:
Low
Water is better at sticking together with other water molecules than it is with the "waxy surfaces".
Red arrows represent the movement of the mantle due to convection. Black arrows represent the movement of the plates due to gravity. Scientists think that this transfer of thermal energy from core to mantle causes convection in the mantle.
