Answer: light reaction produces oxygen and water as we know the general importance of oxygen and water they are useful for organism to survive if plants do not produce oxygen then how could we get oxygen from the environment
<span>1 mol mag acetate dissociates into 1 mol Mg ion and 2 mols acetate ions in water. Therefore, if 0.6 mol mg of acetate is dissolved in 0.135 literss of water, we will have 0.6/0.135 = 4.44 moles / lit Mg2+ ions and 0.6*2/0.135 = 8.88 moles / liter C2H3O2- ions.</span>
According to the reaction equation:
Ba(OH)2 ↔ Ba2+ + 2OH-
when 0.015 M 0.015M 2*0.015M
∴ [OH-] = 0.03 m
so we can get the POH = - ㏒ [OH-]
by substitution:
∴ POH = -㏒ 0.03
= 1.52
and then we can get the PH from this formula:
PH + POH = 14
so by substitution:
∴PH = 14 - 1.52
≈ 12.48
