Why do the two electrons spend their time equally between both hydrogen atoms? In other words, why can’t one hydrogen just take

the other’s electron?

Because it is a covalent bond meaning that they share the electrons to achieve full valence.

An aqueous solution contains 0.29 M of benzoic acid (HA) and 0.16 M of sodium benzoate (A-). If the pH of this solution was meas

Inga [223]

Answer:

pKa = 4.89.

Explanation:

We can solve this problem by using the <em>Henderson-Hasselbach equation</em>, which states:

pH = pKa + log $\frac{[A^-]}{[HA]}$

In this case [A⁻] is the concentration of sodium benzoate and [HA] is the concentration of benzoic acid.

We <u>input the given data</u>:

4.63 = pKa + log $\frac{0.16}{0.29}$

And <u>solve for pKa</u>:

pKa = 4.89

Balance each of the following examples of heterogeneous equilibria and write each reaction quotient, Qc:(b) SnO₂(s) + H₂(g) ⇄ Sn

I am Lyosha [343]

When we balance this equation

SnO₂(s) + H₂(g) ⇄ Sn(s) + H₂O(g)

We will get

SnO₂(s) + 2H₂(g) ⇄ Sn(s) + 2H₂O(g)

Solution:

Balancing this equation

SnO₂(s) + H₂(g) ⇄ Sn(s) + H₂O(g)

We have to balance the number of O

SnO₂(s) + H₂(g) ⇄ Sn(s) + 2H₂O(g)

We have to balance the number of H

SnO₂(s) + 2H₂(g) ⇄ Sn(s) + 2H₂O(g)

We will get the balanced equation

SnO₂(s) + 2H₂(g) ⇄ Sn(s) + 2H₂O(g)

The reaction quotient will be

Qc = [product] / [reactant]

Qc = [Sn(s) + H₂O(g)] / [SnO₂(s) + H₂(g)]
