Answer:
The explanation to your question is below.
Explanation:
In thermochemistry, reactions are classify in two groups.
- Endothermic reactions: are reactions that need energy (heat) from the surroundings to happen. If they are not heated, the products will not form.
Example:
2 H₂O + energy ⇒ 2H₂ + O₂
-Exothermic reactions: are reactions that release energy to the surroundings. They happen spontaneously.
Example:
CH₄ + 2O₂ ⇒ CO₂ + 2H₂O + energy (heat)

Sulfur Dioxide is 2.86 g/L
Methane is 0.174 g/L
