A. Thermal energy good job
Answer:
HCl(aq) + KOH(aq) ⇒ KCl(aq) + H₂O(l)
Explanation:
Hydrochloric acid is an acid because it releases H⁺ in an aqueous solution.
Potassium hydroxide is a base because it releases OH⁻ in an aqueous solution.
When an acid reacts with a base they form a salt and water. This is a neutralization reaction. The neutralization reaction between hydrochloric acid and potassium hydroxide is:
HCl(aq) + KOH(aq) ⇒ KCl(aq) + H₂O(l)
Answer:
Kinetic energies of all the gases are same.
Explanation:
The average kinetic energy of molecules of a gas is given by the formula:
K.E = (3/2)KT
where,
K.E = Average Kinetic Energy of the molecule
K = Boltzman's Constant = 1.38 x 10^-23 J/K
T = Absolute temperature of gas
Since, all the gases are in a mixture, and the temperature of the gases must be same and equal to the temperature of mixture.
Therefore, all the terms in the formula are constant and the <u>Average Kinetic Eenergies of all the gases in the mixture (namely, Neon Ne, Krypton Kr, Radon Rn), equal.</u>
