Neither N₂ or O₂ are greenhouses gases because they do not cause the greenhouse effect.
<h3>What are greenhouses gases?</h3>
Greenhouse gases trap heat in the atmosphere causing the temperature of the planet to rise.
Greenhouse gases cause the greenhouse effect.
<h3>What is the greenhouse effect?</h3>
The greenhouse effect is the warming up of the planet due to greenhouse gases.
Greenhouse gases include
- carbondioxide
- methane
- nitrous oxide and
- water vapour
So, neither N₂ or O₂ are greenhouses gases because they do not cause the greenhouse effect.

V ( HCl ) = 45.00 mL in liters : 45.00 / 1000 => 0.045 L
M ( HCl ) = ?
V ( NaOH ) = 25.00 / 1000 => 0.025 L
M ( NaOH) = 0.2000 M
number of moles NaOH :
n = M x V = 0.2000 x 0.025 => 0.005 moles of NaOH
Mole ratio:
HCl + NaOH = NaCl + H2O
1 mole HCl ---------- 1 mole NaOH
? mole HCl ---------- 0.005 moles NaOH
moles HCl = 0.005 x 1 / 1
= 0.005 moles of HCl :
M ( HCl ) = n / V
M ( HCl ) = 0.005 / 0.045
= 0.1111 M
hope this helps!
