Answer:
80 ml
Explanation:
From the question,
Applying Dilution formular
MV = mv................... Equation 1
Where M = Molarity of Kl before dilution, V = Volume of Kl before dilution, m = molarity of Kl after dilution, v = volume of Kl after dilution.
make V the subject of the equation
V = mv/M............. Equation 2
Given: m = 1.00 M, v = 200 ml, M = 2.50 M
Substitute these values into equation 2
V = (1.00×200)/2.50
V = 80 ml
Answer is: more H⁺ ions than OH⁻ ions.
<span>An Arrhenius acid is a
substance that dissociates in water to form hydrogen ions or
protons.
For example, hydrochloric acid dissociate in aqueous
solution to form hydrogen ions (H</span>⁺)
and chloride anion (Cl⁻):<span>
HCl(aq) → H</span>⁺(aq) + Cl⁻<span>(aq).

An Arrhenius base is a
substance that dissociates in water to form hydroxide ions (OH⁻<span>).
For example lithium hydroxide is an Arrhenius base:</span>
LiOH(aq) → Li⁺(aq) + OH⁻(aq).
Hydrogen and Oxygen. You need two hydrogen atoms and one oxygen atom to make up H2O
A as if the cell is placed in a solution with the same solute and water potential as it no water moves in nor out so the cells remains in homoeostasis
hope that helps
