Answer:

$A\text{ : 155 cal}$

Explanation:

Here, we want to convert J to cal

Mathematically:

$1\text{ cal = 4.186 J}$

Thus, to get our answer in cal, we divide the value given by 4.186

We have that as:

$\frac{650}{4.186}\text{ = 155 cal}$

Answer:

The answer is " $32819.9 \ \frac{J}{mol}\\\\$ "

Explanation:

$Boron: 5^{B}\to 1s^2 2s^2 2p^1$

$\Delta E=-2.18\times 10^{-18}\ \frac{J}{atom}\ (\frac{1}{\infity^2}-\frac{1}{n^2_{initial}})(z^2) (6.022\times 10^{23}\ \frac{atom}{mol})\\\\$

$=-2.18\times 10^{-18}\ \frac{J}{atom}\ (0-\frac{1}{1})(5^2) (6.022\times 10^{23}\ \frac{atom}{mol})\\\\ =2.18\times 10^{-18}\times 25 \times 6.022\times 10^{23}\ (\frac{J}{mol})\\\\ =328.199 \times 10^{5}\ (\frac{J}{mol})\\\\ =32819 \times 10^{3}\ (\frac{J}{mol})\\\\ =32819.9 \ (\frac{J}{mol})\\\\$
