andrey2020 [161]

Answer:

$V_2=8L$

Explanation:

Hello there!

In this case, considering the Avogadro's gas law, which treats the volume and moles in a directly proportional way via:

$\frac{V_1}{n_1}=\frac{V_2}{n_2}$

Which can be solved for the final volume, V2, as shown below:

$V_2=\frac{V_1n_2}{n_1}$

Thus, by plugging in the given data, we obtain:

$V_2=\frac{4L*(0.250mol+0.250mol)}{0.250mol}\\\\V_2=8L$

For Mn3+, write an equation that shows how the cation acts as an acid.

Mkey [24]

An acid is a compound which will give H+ ions or H3O^+ ions

the reaction will be

$[Mn(H_{2}O )_{6} ^{+3} +H_{2}O --> [MnOH(H_{2}O)_{5}]^{+2} + H_{3}O^{+}$

Thus as there is evolution of H_{3}O^{+} the Mn+3 is an acid
