Answer:
See explanation
Explanation:
The electron configuration of an atom means a detailed arrangement of the electrons in the atom in orbitals. It normally begins from the least energetic orbitals to the most energetic orbital.
For each of the elements, their electronic configuration in terms of the nearest noble gas is shown below;
P - [Ne] 3s2 3p3
I- [Kr] 4d10 5s2 5p5
Pb- [Xe] 4f14 5d10 6s2 6p2
F- [He] 2s2 2p5
Explanation:
A distilled water is the correct anwser
Answer:
119.5 J
Explanation:
First we <u>calculate the temperature difference</u>:
- ΔT = 100 °C - 50 °C = 50 °C
Then we can <u>calculate the heat released</u> by using the following formula:
Where q is the heat, Cp is the specific heat, ΔT is the temperature difference and m is the mass.
We <u>input the data</u>:
- q = 0.239 J/g°C * 50 °C * 10.0 g
