Answer:D
Explanation:
options A-C has the option pepsi which is an enzyme that is active in the stomach with a PH of 2.
Answer;
Molarity of NaOH is 0.80 M
Explanation;
The balanced equation for the reaction is;
2NaOH(aq) + H2SO4(aq = NaSO4(aq) +2 H2O (l)
Moles = concentration x volume
thus; 0.355M x 0.0282L= 0.01 moles of H2SO4.
Using the mole ratio;
Moles of NaOH = Moles of H2SO4 ×2
= 0.02 Moles
Therefore; moles of NaOH = 0.02 moles
But; Concentration = moles / volume
Thus; Concentration of NaOH = 0.02 / 0.025L
= 0.8M
