Will mark BRAINLIEST!
Nataliya [291]

Answer:

Explanation:

2 NO2(g) ⇄ N2O4(g)

Adding Argon to this reaction will have NO effect. Catalysts nor inert gases have an affect on equilibrium conditions.

Only changes in concentration, temperature conditions and pressure-volume conditions (unless both sides have equal molar volumes) will affect the equilibria.  

NH4OH(aq) ⇄ NH3(g) + H2O(l)

Removing ammonia from reaction equilibrium causes the reaction to shift right to replace removed ammonia. => Think of the reaction as being on a seesaw => removing ammonia from the product side tilts the seesaw left causing the NH₄OH to decompose and deliver more NH₃ and H₂O to the product side to increase weight on that side and level the seesaw. :-)

Which bases can deprotonate acetylene? the pka values of the conjugate acids are given in parentheses. select all that apply. ch
Usimov [2.4K]

pKa is a value which is related to the acid dissociation constant Ka

pKa = -log Ka

i.e. Ka = 10^-pKa

The deprotonation reaction of acetylene is:

HC≡CH ↔ HC≡C⁻ + H⁺

pKa (HC≡CH) = 25

Solvents with pKa greater than 25 will deprotonate acetylene.

Ans: CH2=CH⁻ pka = 44 and CH3NH⁻ pka = 40
