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.

Answer:
B
Explanation:
Solar power takes in light and turns it into a usable energy. if used in a vehicle that would take light energy and transform it into mechanical energy.
I think A would be the correct answer to this question.
Answer:
A dunes windward side is the side where the wind is blowing and pushing material up. A dunes slip face is simply the side without wind. A slipface is usually smoother than a dunes windward side. A collection of dunes is called a dune belt or dune field.

1. 12 L = 12 dm³
2. 3.18 g
<h3>Further explanation</h3>
Given
1. Reaction
K₂CO₃+2HNO₃⇒ 2KNO₃+H₂O+CO₂
69 g K₂CO₃
2. 0.03 mol/L Na₂CO₃
Required
1. volume of CO₂
2. mass Na₂CO₃
Solution
1. mol K₂CO₃(MW=138 g/mol) :
= 69 : 138
= 0.5
mol ratio of K₂CO₃ : CO₂ = 1 : 1, so mol CO₂ = 0.5
Assume at RTP(25 C, 1 atm) 1 mol gas = 24 L, so volume CO₂ :
= 0.5 x 24 L
= 12 L
2. M Na₂CO₃ = 0.03 M
Volume = 1 L
mol Na₂CO₃ :
= M x V
= 0.03 x 1
= 0.03 moles
Mass Na₂CO₃(MW=106 g/mol) :
= mol x MW
= 0.03 x 106
= 3.18 g
