Mass : actual amount of material contained in a body. It is independant of where you are.
Weight: force that gravity puts on a mass.
On Earth, gravity is 9.80 m/s^2compared to 1.62 m/s^2 on the moon.
Weight=mass *gravity
Moon : (example)
10 kg* 1.62 m/s^2= 16.2 N ( Newton is the unit for weight)
Earth:
10*9.80= 98 N
The answer is C. One item replacing another is a single replacement, but when two items trade places in two separate molecules it’s double replacement.
Explanation:
P₄+O₂=P₂O₃; non-balanced
P₄+O₂=2P₂O₃; to add '2' on the right side; non-balanced
P₄+3O₂=2P₂O₃. to add '3' before O₂ in the left side; balanced
