Answer:
4p
Explanation:
3s < 3p < 4s < 4p
This arrangement is in order of increasing energy.
This explains that, 4p is the highest energy level you can reach.
The answer is 3. The releasing of energy means exothermic reaction. So the ΔH should be negative. And the greatest quantity of energy released means that the greatest number. So according to the table I, the answer is 3.

Answer:</h3>
1257.45 L
<h3>
Explanation:</h3>
We are given;
- Initial volume of Helium gas, V1 as 806 L
- Initial temperature of Helium gas,T1 as 20.9°C
- Initial pressure of Helium gas, P1 as 753 mmHg
- Pressure of Helium at the altitude 6.8 km, P2 as 417 mmHg
- Temperature of Helium gas at the altitude 6.8 Km, T2 as -19.1°C
But, K = °C + 273.15
Therefore, T1 = 294.05 K and T2 = 254.05 K
- We are required to calculate the new volume of the balloon at 6.8 km.
- To determine the new volume we are going to use the combined gas law.
- According to the combined gas law,

Thus, rearranging the formula;



Therefore, the volume of the balloon at an altitude of 6.8 km is 1257.45 L
If iron (Fe) gained a proton it would become cobalt (CO).
