The starting substances in a chemical reaction are called reactants - they are written on the left side of a chemical equation.
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

Hey there
Explanation:
The process where organisms better adapted to their environment tend to survive and produce more offspring is called natural selection. It is one of the points of Darwinism by Charles Darwin.
