Answer:
Boron (B) is the element whose IE matches with our data.
Electronic Configuration of boron: 
Explanation:
Ionization Energy (IE):
It is the minimum amount of energy which is required to remove the lose electron. If the electron is closer to the nucleus then greater amount of energy is required to remove the electron.
If we look from left to right in a period, ionization energy increases due stability of valance shell.
From the data given to us:
IE₁ = 801
IE₂ = 2427
IE₃ = 3659
IE₄ = 25,022
IE₅ = 32,822
Boron (B) is the element whose IE matches with our data.
Electronic Configuration of boron:
Boron has 5 electrons (3 in valance shell) that's why it has 5 Ionization Energies.
The answer will be, so3 since s only need two electrons to complete its octet

its to small I can't see it
In accordance with Dalton's Law of multiple proportions

Solution
the amount of air present ⇒ as an excess or limiting reactant
- air(O₂) as a limiting reactant(product=14 g)
C+0.5O₂⇒CO
6 + 8 = 14 g
mol O₂=8 g : 32 g/mol=0.25
mol C = 6 g : 12 g/mol = 0.5(2 x mol O₂)
mol CO= 2 x mol O₂ = 0.5 mol = 0.5 x 28 g/mol = 14 g
- air(O₂) as an excess reactant(product=22 g) an C as a limiting reactant
C+O₂⇒CO₂
6 + 16 = 22 g
mol C = 6 g : 12 g/mol = 0.5
mol O₂ = 16 g : 32 g/mol=0.5
mol CO₂ = 22 g : 44 g/mol = 0.5
if the mass firs element (C) constant, then the mass of the second element(O) in the two compounds will have a ratio as a simple integer.
CO = 6 : 8
CO₂ = 6 : 16
the ratio O = 8 : 16 = 1 : 2
In accordance with Dalton's Law of multiple proportions
The temperature of the nitrogen gas is 292.5 K.
<u>Explanation:</u>
Given that
Moles of Nitrogen, n = 5 mol
Volume, V = 30 L
Pressure, P = 4 atm
Gas Constant, R = 0.08205 L atm mol⁻¹ K⁻¹
Temperature = ? K
We have to use the ideal gas equation,
PV = nRT
by rearranging the equation, so that the equation becomes,
T = 
Plugin the above values, we will get,
T = 
= 292.5 K
So the temperature of the nitrogen gas is 292.5 K.
