The electrolyte is H₃PO₄, this is because it releases H⁺ ions and PO₄⁻³ ions when it is dissolved in water
In chemistry, an electrolyte is a substance that has the capacity of conducting electric current by dissociating into positively and negatively charged ions, which migrate to the cathode and anode of an electric circuit, respectively.
From the given information;
The electrolyte is H₃PO₄, this is because it releases H⁺ ions and PO₄⁻³ ions when it is dissolved in water.

Given:
Molar mass CO2 is 44.01 g/mol
25.5 g of CO2
Required:
Moles of LiOH
Solution:
Balanced equation is:
2LiOH +CO2 → Li2CO3 + H2O
25.5g CO2 (1 mole CO2/44.01 g/mol CO2)(2 moles LiOH/1 mol CO2) = 1.16 moles LiOH
Molarmass carbon dioxide is 44.01 g/mol, 1.16 moles of LiOH are needed to react completely with 25.5 g of CO₂.
Stoichiometry and the molar ratios of CO₂ and LiOH must be used to calculate the number of moles of LiOH required to totally react with 25.5 g of CO₂.
The reaction between CO₂ and LiOH has the following chemical formula:
CO₂ + 2LiOH -> Li₂CO₃ + H₂O
Now,
Molar mass of CO₂ = 44.01 g/mol
Mass of CO₂ = 25.5 g
Number of moles of CO₂ = Mass of CO2 / Molar mass of CO2
= 25.5 g / 44.01 g/mol
≈ 0.58 moles of CO2
As per this,
Number of moles of LiOH = 2 * Number of moles of CO2
= 2 * 0.58 moles
= 1.16 moles of LiOH
Thus, 1.16 moles of LiOH are needed for the given reaction.

Answer:
explained below.
Explanation:
World war 1 leads to suffer the Americans people a lot .
Young men were forced to go for war which leads to the deplete the financial condition of the house hold. Industry starts to suffer a lot as most of the people who were working has to go for war and man power decreases.
Which leads women to come out of there houses and took job for them so, that they can full fill there needs which starts the new era where woman also start working with men.
B. limited the material in which natural selection can act upon.
C. increased genetic variation.
D. maintained the same gene combinations over time.
