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
Answer:
1) Atomic number = number of proton or electrons
Mass number = number of proton or electron + number of neutron
I believe your answer will be 40
The correct SI system to use the measuring the mass of a boulder is Kilograms.
