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

Answer:
Explanation:
We know the area of the rectangle is length * width
We also know width = length - 5
Thus area is 
If an angle of a parallelogram is two-third of its adjacent angle, then the smallest angle of the parallelogram is 72°. Adjacent angles exhibit a common side and a corner point.
Adjacent angles exhibit a common side and a corner point, although they do not overlap.
A parallelogram can be defined as a simple type of quadrilateral having two pairs of parallel sides.
A rectangle can in turn be defined as a parallelogram having four right angles (90°), thereby all rectangles represent quadrilaterals.
The sum of the adjacent angles of a parallelogram is equal to 180°.
In this case, we have that the sum of adjacent angles >> X + 2/3 X = 180° >> X = 108° >> 2/3 X = 72°

Answer:
I used the function 1-proportion z-interval on the calculator, where I inputted
- Successes(x) = 64
- Sample size(n) = 593
- Confidence Level(C level) = 0.99
It would result in zInterval_1Prop 64,593,0.99: stat.results, where the values are shown below as:
- Lower bound (CLower) = 0.075105
- Upper bound (CUpper) = 0.140747
- test statistic (p^) = 0.107926
- Margin of error (ME) = 0.032821
Therefore, the 99% confidence interval would be around 0.11 ± 0.03 or range from 0.08 to 0.14.

There are different kinds of angles. The statement that will accurately correct the two-column proof is that the definition of angle on a straight line.
<h3>What is straight angle?
</h3>
- This is an angle whose sides sit in opposite directions from the vertex usually in the same straight line and is said to be equals two right angles.
Two angles are known to be supplementary when their measures if sum up reaches 180 degrees.
Conclusively, Looking at the angle, m∠ZRY = 180°, this is because angle ZRY is a straight angle and it is not a supplementary angle.
Therefore option A is the correct answer (Image attached)
