It indicates that there is only one oxygen molecule
I believe it’s D because phosphorus has the mass of 30.9.
Answer:
3) Ionic
Explanation:
The solid formed when a bond occurs between magnesium and oxygen is an ionic bond. This bond type occurs between a metal and non-metal.
- Magnesium is the metal
- Oxygen is the non - metal
- Due to the large electronegativity difference between the two species, the metal loses electrons which the non-metal oxygen gains
- They both complete their octet and electrostatic attraction leads to the formation of ionic bonds.
A.) Average acceleration = change in velocity/time = final velocity - initial velocity/time = 10-0/4 = 10/4 = 2.5m/s^2.
