Explanation:
As the given chemical reaction equation is as follows.
![2Cl_{2}(g) + 7O_{2}(g) + 130 kcal \rightarrow 2Cl_{2}O_{7}(g)](https://tex.z-dn.net/?f=2Cl_%7B2%7D%28g%29%20%2B%207O_%7B2%7D%28g%29%20%2B%20130%20kcal%20%5Crightarrow%202Cl_%7B2%7DO_%7B7%7D%28g%29)
Also, it is given that for 2 moles the energy required is 130 kcal. This means that energy required for 1 mole is calculated as follows.
1 mole = ![\frac{130 kcal}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B130%20kcal%7D%7B2%7D)
= 65 kcal
Hence, energy required for 7 moles will be calculated as follows.
Energy required = ![7 \times 65 kcal](https://tex.z-dn.net/?f=7%20%5Ctimes%2065%20kcal)
= 455 kcal
Thus, we can conclude that energy required to produce 7.00 mol
on the basis of given reaction is 455 kcal.
Answer:
(1) 720 seconds (2) 10800 seconds (3) 17 dozens (4) 1.45 x
(5) 13.29 moles
Explanation:
(1) 720 seconds
1 minute = 60 seconds
12 minutes = 720 seconds (12 x 60)
(2) 10800 seconds
1 hour = 60 minutes 1 minute = 60 seconds
3 x 60 = 180 minutes in 3 hours
180 x 60 = 10800 seconds in 180 minutes that are in 3 hours
(3) 17 dozens
1 dozen = 12
204 ÷ 12 = 17 dozens
(4) 1.45 x ![10^{25}](https://tex.z-dn.net/?f=10%5E%7B25%7D)
8.00 moles CO2 x
= 24.0 moles atoms
24.0 moles x
= 1.45 x ![10^{25}](https://tex.z-dn.net/?f=10%5E%7B25%7D)
(5) 13.29 moles
sorry but I'm not fully sure if this one is correct

Answer:
The total number of electrons in a valence shell is called valence electrons. The electron configuration of rubidium shows that the last shell of rubidium has an electron. Therefore, the valence electrons of rubidium(Rb) are one.
