Consider the four free body diagrams. Free-body diagrams are diagrams used to show the relative magnitude and direction of all f
orces acting upon an object in a given situation. Do any of the free body diagrams indicate motion? If yes, which one(s). Explain.
A)
No. In each case, the forces are balanced.
B)
Yes. In B the book is slowing down because of the friction force opposing motion.
C)
You cannot tell if there is any motion. You can only determine how much force is acting on the objects.
D)
Yes. In B and D. In both cases, there is a net force.
In B, there is a net force to the left; in D there is a net force upward.

Answer:
30 moles of CO₂
Explanation:
balanced equation ,
CS₂+3O₂ → CO₂+2SO₂
From equation, 3 moles of O₂ are needed to make 1 mol of CO₂.
This means to produce 1 mol of CO₂, we need 3 moles of O₂, then how many moles of CO₂ will be produced from 90 moles of O₂ ?
Use unitary method to solve such problems,
Number of moles of CO₂ that will be produced:
=
=
= 30 moles of CO₂
