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

The graph that shows the sampling distribution of the sample minimum age is; Option C Graph
<h3>Sampling distribution</h3>
We are given the ages of the 5 teachers as;
23, 34, 37, 42 and 58.
- The options that show the sampling distribution of the sample minimum age has been attached.
Since 4 teachers will be selected out of the 5, it means that the minimum age of the 4 selected teachers will be 23 years of age 4 time while the minimum age will be 34 if the 23 year old teacher is not selected.
- In conclusion, the sampling distribution for this scenario of minimum age should show 4 teachers at the 23 year mark and 1 teacher at the 34 year mark.

Lack of direction is one of the most common organizational problems and it stems from two root causes: The leader or leaders rarely discuss or chart a deliberate direction or strategy for the future, or they fail to communicate a coherent message about the strategy to all members of the organization. Hopefully this helped.
