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:
for its one mole it is of 28gram. according to mole concept in one mole, there is 6.022*10^23 moles are present. so mass of 1 molecule of nitogen gas is 28/(6.022*10^23)
Answer:
2:3
You'd need 33.3 moles of potassium chlorate, KClO3 , to produce that much oxygen. Notice that you have a 2:3. mole ratio between potassium chlorate and oxygen gas, which means that, regardless of how many moles of the former react, you'll always produce 3/2 times more moles of the latter.
Explanation:
You cannot create something from nothing and similarly you cannot create less from more, if you didn't balance an equation that needs to be balanced, your product might end up equalling more or less than the total mass of the two elements combined. Which is impossible
