The pair of substances that would most likely result in the production of a gas when reacting with an acid would be soluble metal salt and carbon dioxide.
The volume of the gas has increased and temperature and volume are directly proportional, thus, the temperature of the gas must also have increased.
We can use the relationship:
V/T = constant
V₁/T₁ = V₂/T₂
200 / (-73 + 273) = 300 / T₂
= 300 K

Answer:
The concentration of the pyridinium cation at equilibrium is 1.00×10⁻³ M
Explanation:
In water we have
C₅H₅NHBr + H₂O ⇒ C₅H₅NH+ + Br−
Pyridinium Bromide (C₅H₅NHBr) Dissociates Completely Into C₅H₅NH+ And Br− as such it is a strong Electrolyte.
Therefore the number of moles of positive ion produced per mole of C₅H₅NHBr is one
pH = - log [H₃O⁺] Therefore 10^-pH = [H₃O⁺] = concentration of C₅H₅NHBr
= 10⁻³ = 0.001M = concentration of C₅H₅NHBr
The concentration of C₅H₅NHBr is = 1.00×10⁻³ M to two places of decimal
