I don't see an image, but I'm going to assume B) At.
<span>Rusting of iron is one form of oxidation. Whether a substance oxidizes or corrodes describes a chemical property of matter.
HOPE THIS HELPS! ^_^</span>
Body surface area (BSA) is a measurement of the surface of the body using height and weight. It acts as a better indicator of metabolic mass compared to body weight since it is not affected by abnormal adipose mass.
BSA = (Height × Body weight) ÷ 3131
= (63 × 167) ÷ 3131 = 1.83 m²
The body surface area for the woman is 1.83 m²
Explanation:
The given reaction is as follows.
Hence, number of moles of NaOH are as follows.
n =
= 0.005 mol
After the addition of 25 ml of base, the pH of a solution is 3.62. Hence, moles of NaOH is 25 ml base are as follows.
n =
= 0.0025 mol
According to ICE table,
Initial: 0.005 mol 0.0025 mol 0 0
Change: -0.0025 mol -0.0025 mol +0.0025 mol
Equibm: 0.0025 mol 0 0.0025 mol
Hence, concentrations of HA and NaA are calculated as follows.
[HA] =
[NaA] =
Now, we will calculate the value as follows.
pH =
=
= 3.42
Thus, we can conclude that of the weak acid is 3.42.
