Answer:
8
Explanation:
Methyl anion (CH₃⁻)
Valence electrons of carbon = 4
Valence electrons of hydrogen = 1
Charge = -1 which means addition of 1 electron
The total number of the valence electrons = 4 + 3(1) + 1 = 8
<u>In the Lewis structure of anion also, 1 lone pair and 3 bond pairs on the carbon atom which corresponds to 8 valence electrons.</u>

Answer:
1.36x10^-19 J
Explanation:
First, we need to write the bohr's equation for the energy levels:
E(n) = -1/n² * 13.6 eV
Now, the question is asking this energy in Joules, so at the end we will use the conversion of eV to Joules.
As the energy level is 4, we just replace the value of n = 4 in the equation and solve for the energy in eV first:
E(4) = -1/4² * 13.6
E(4) = -0.85 eV
Now, the conversion for eV to Joules is the following:
1 eV = 1.6022x10^-19 J
Therefore, we just need to multiply the obtained value of Energy in eV with this factor, and we have the energy in Joules as required:
E = -0.85 * 1.6022x10^-19
E = 1.36x10^-19 J
This is the energy in Joules for an electron in the level 4.
According to Charles' law for ideal gases, at constant pressure, the volume and temperature of a given mass of gas with same number of moles are directly proportional to each other. This means, if volume increases then temperature will also increase whereas, if volume decreases then temperature will also decrease. For this reason, a small increase in volume will increase the temperature of the gas.
Therefore,
Volume ∝ Temperature in Kelvin scale.
V ∝ T
