need 0.500 x 0.125 = 0.0625 moles of NaOH. The molecular weight is 23+16+1 = 40, so 0.0625 x 40 = 2.5 grams will do the trick.
Since the pH of the substance is 5, the substance contains more of hydrogen ions.
<h3>What is pH of a solution?</h3>
The pH of a a solution is the negative logarithm to base ten of the hydrogen ions concentration of the solution.
![pH = -log[H^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5BH%5E%7B%2B%7D%5D)
A neural solution has pH 7.
A solution with pH below 7 has more hydrogen ions while a solution with pH above 7 has more hydroxide ions.
The pH of a substance contains a hydrogen ion concentration of 1.0 x 10-5 M is 5.
Therefore, the substance contains more of hydrogen ions.

Answer:
Glucose also called(Energy)
Answer: There will be a shift toward the products.
The effect of increasing volume will be similar to decreasing pressure, it will shift the equilibrium into the side with higher molecule count. In the reaction above, the product molecule count is 1 (one PCl5) while the product is 2 (one PCl3 + one Cl2). So, increasing volume will increase the rate of product formation.
