Answer is: HCl (hydrochloric acid) <span>will have the largest amount of conjugate base.
Hydrochloric acid is the strongest acid present in this question, because it has largest Ka value:
pKa(HCl) = -8.
Ka(HCl) = 10</span>∧(-pKa).
Ka(HCl) = 10⁸.
Chemical dissotiation of hydrochloric acid:
HCl(aq) → H⁺(aq) + Cl⁻(aq).
Ka(HCl) = [H⁺]·[Cl⁻] / [HCl].
Concentration of Cl⁻ ions (conjugate base of hydrochloric acid) is very high.
Southern hemisphere
most of South America, one-third of Africa, all of Antarctica, a small sliver of Asia (parts of Indonesia) and all of Australia/Oceania.
Energy in a chemical reaction is not created nor destroyed, it's always conserved based on the law of conservation of energy.
40,500 mg---> 3 SF Zeros to the left of an understood decimal point and at tge same time to the right of a non zero number and not significant. The zero in between non zeros(4&5) is significant.
1) Calculate the number of moles in 1.15 liter of 0.100 M HNO3 solution.
M = n / V => n = M*V = 0.100M * 1.15 l = 0.115 moles
2) Calculate the mass of 0.115 moles of HNO3
mass = number of moles * molar mass
molar mass of HNO3 = 1.00 g/mol + 14.0 g/mol + 3*16.0g/mol = 63.0 g/mol
mass = 0.115 mol * 63.0g/mol = 7.245 g
3) Calculate the mass of 70.3% HNO3 solution that contains 7.245 grams of HNO3
% = (mass of solute / mass of solution) * 100
=> mass of solution = mass of solute * 100 / % = 7.245 g * 100 / 70.3%
mass of soltuion = 10.3 g.
4) Convert 10.3 grams of HNO3 solution into volume, using density, D
D =mass / Volume => Volume = mass / D
=. Volume = 10.3 g / 1.41 g/cm^3 = 7.30 cm^3
Answer: 7.30 cm^3
