When opposing forces act on an object, this means that the object isn't moving at all. This is also known as a "balanced force." If the forces of the same and you add them together the answer is 0.

Answer:
99•g
Explanation:
Well, ONE mole of water has a mass of 18.01⋅g⋅mol−1. and 5.5⋅mol has a mass of approx. <u>99⋅g.</u>
I think it's dependent variable.
Burning Mg in the air and reacting with O2 forming a white powder of MnO
So the equation is going to be:
Mn + O2 ⇒ MnO (this equation is not conserved)
to make it equilibrium:
1- First we should put 2Mno to equal the O2 on both sides.
So it will be:
Mg + O2⇒ 2MgO
2- Second we should put 2Mn to equal the Mn on both sides.
2Mg + O2⇒ 2MgO (this equation is conserved)
After putting the physical states the final equilibrium equation is going to be:
Δ
2Mg(s) + O2(g)⇒ 2MgO(s)
