Br2 == 2Br
24% dissociated => n total moles, 0.24 mol*n of Br, and 0.76*n mol of Br2
=> partial pressure of Br, P Br = 0.24 bar, and
partical pressure of Br2, P Br2 = 0.76 bar
kp = (P Br)^2 / P Br2 = (0.24)^2 / 0.76 = 0.0758
Answer : Molecular compounds dissolve in water by means of dipole-dipole attractions and hydrogen bond attractions. These attractions between the molecular compound and water don't form ions when a molecular compound dissolves.
Explanation: I hoped that helped,
1.) Calculate the change in pH when 4.00 ml of 0.100 M HCl(aq) is added to 0.100 mL of a buffer solution that is 0.100 M in NH3 (aq) and 0.1000 M in NH4Cl(aq).
2.) Calculate the change in pH when 4.00 mL of 0.100 M in NaOH(aq) is added to the original buffer solution.
Answer:
Answer is: A. Vinegar and soda.
Neutralization is is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH) and a base (in this example soda or some other base) react quantitatively with each other.
Balanced chemical reaction of vinegar and soda:
CH₃COOH(aq) + Na⁺(aq) → CH₃COONa(aq) + H⁺(aq).
Sodium acetate (CH₃COONa) is a salt.
Answer:
When the moles of the reactant is equal to the mole of the product.
