B. since Phosphorus has an atomic mass of 30.974 (larger) than Magnesium which is 24.305 (smaller)
Greater density means to greater mass and greater mass to more gravity on the body
Formula of work done, W = - P (final volume - initial volume)
Here, W = work done
P = external pressure
External pressure is constant. In case of expansion final volume is greater than initial volume, therefore change in volume is positive.
W = negative ( positive )
W = negative
So, In case of expansion, the negative value of work indicates that the work is done by the system on the surrounding. Energy is released by system.
The sum of the forces of all of the molecules placing the wall divided by using the area of the wall is described to be the pressure. The pressure of a gasoline is then a measure of the common linear momentum of the moving molecules of a gas. The unit of pressure is pascal.

Explanation:
Carbon is a non-metal then carbon dioxide is a non-metal oxide. Non-metal oxides reacts with water to produce acids.
non-metal oxide + water ----> acid
carbon dioxide + water ----> carbonic acid
CO₂ + H₂O ---> H₂CO₃
Answer: H₂CO₃ (H2CO3)
