In the reaction, 2H2 + O2 --> 2H2O, how many hydrogen molecules are needed to produce two water molecules?

1 answer:

5 0

2 is the correct answer because with 2O2 molecules it balances the chemical equation.

Hope that helps

Answer:

Equilibrium will lie to the right.

Explanation:

$K_{a}(HF)> K_{a}(C_{6}H_{5}COOH)$

That means HF is stronger acid than $C_{6}H_{5}COOH$ .

Alternatively, it can be said that $C_{6}H_{5}COO^{-}$ is a stronger base than $F^{-}$ .

Therefore HF readily gives proton to $C_{6}H_{5}COO^{-}$ to form $C_{6}H_{5}COOH$ and $F^{-}$ than the reverse reaction.

So, the equilibrium will lie more towards the right i.e. towards formation of $C_{6}H_{5}COOH$ and $F^{-}$ .
