Um... I might be wrong but I think it would be A. Photosynthesis
Answer:
c. 7.14
Explanation:
The buffer solution is formed by a weak acid ( hypochlorous acid, HClO) and its conjugate base (hypochlorite ClO⁻, coming from sodium hypochlorite NaClO). We can calculate the pH using the Henderson-Hasselbach equation.
pH = pKa + log [base]/[acid]
pH = -log 3.8 × 10⁻⁸ + log 0.111/0.211
pH = 7.14
Chromium nitride
Chromium nitride is a chemical compound of chromium and nitrogen with the formula CrN.
Answer:
the range should be 2.2 to 4.3
Explanation:
I think so because the numbers at the left side of the scale from 1 are more acidic so as it increases it's still acidic but lesser so 1 is more acidic than 2 so I used 2.2 as the beginning of the range because it's less acidic than A even though its a greater number and 4.3 is lesser than 4.4 but its still greater on the scale. frankly speaking I don't feel so correct because it's in decimal so try and compare facts thank you
