Question:
Which situation describes the best example of rotational motion?
A. Craig sent the pool ball spinning toward the side pocket.
B. The skater repeated the figure eight on the ice.
C. Sara spun the dreidel on its pointed end.
D. The mouse ran in circles around the mousetrap.
Answer :
C
Explanation:
It's C, because it is spinning. It can't be D because it's going in a circle, not spinning. it can't be A because it doesn't really make sense. It can't be B because the Skater is repeating, not rotating. So the only logical answer is C.

I'm really sorry but you didn't gave any options...
The number of mole of carbon dioxide, CO₂ formed from the reaction is 0.0632 mole.
<h3>How to determine the mole of NaHCO₃</h3>
- Molarity of NaHCO₃ = 2 M
- Volume = 31.6 mL = 31.6 / 1000 = 0.0316 M
- Mole of NaHCO₃ =?
Mole = Molarity x Volume
Mole of NaHCO₃ = 2 × 0.0316
Mole of NaHCO₃ = 0.0632 mole
<h3>How to determine the mole of CO₂</h3>
NaHCO₃ + HCl —> CO₂ + H₂O + NaCl
From the balanced equation above,
1 mole of NaHCO₃ reacted to produce 1 mole of CO₂.
Therefore,
0.0632 mole of NaHCO₃ will also react to produce 0.0632 mole of CO₂.
Thus, 0.0632 mole of CO₂ was obtained from the reaction
