Explanation:
The one closest to the atomic center, there is a single 1s orbital that can hold 2 electrons. At the next energy level, there are four orbitals.
Answer:
9.63 Km is the equivalent to 9,630 m.
9.63 Km is the equivalent to 9,630 m. TRUE
Answer: Dinitrogen pentoxide
Explanation:
The heat lost is ![-7.32*10^-^5J](https://tex.z-dn.net/?f=-7.32%2A10%5E-%5E5J)
The heat lost when the ice is cooled from 400k to 263K can be calculated using the formula of heat transfer.
<h3>Heat Transfer</h3>
This is the heat transferred from a body of higher temperature to a body of lower temperature.
![Q = mc(\delta)T](https://tex.z-dn.net/?f=Q%20%3D%20mc%28%5Cdelta%29T)
- Q = Heat Transfer
- m = mass = 1277g
- ΔT = change in temperature
![\delta T = (400 - 273) - (263 - 273) = \\ \delta T = T_2 - T_1\\ \delta T = -10 - 127\\ \delta T = -137^0C](https://tex.z-dn.net/?f=%5Cdelta%20T%20%3D%20%28400%20-%20273%29%20-%20%28263%20-%20273%29%20%3D%20%5C%5C%0A%5Cdelta%20T%20%3D%20T_2%20-%20T_1%5C%5C%0A%5Cdelta%20T%20%3D%20-10%20-%20127%5C%5C%0A%5Cdelta%20T%20%3D%20-137%5E0C)
We converted the temperature from kelvin scale into Celsius scale and find the change in temperature.
Solving for heat transfer
![Q = mc\delta T\\ Q = 1277 * 4.186 * -137\\ Q = -732336.514J](https://tex.z-dn.net/?f=Q%20%3D%20mc%5Cdelta%20T%5C%5C%0AQ%20%3D%201277%20%2A%204.186%20%2A%20-137%5C%5C%0AQ%20%3D%20-732336.514J)
The heat loss is approximately ![-7.32*10^-^5J](https://tex.z-dn.net/?f=-7.32%2A10%5E-%5E5J)
