# Explanation:
## Step1: Write reaction reactants
$	ext{CO}_2 + 	ext{H}_2	ext{O}$
## Step2: Add product and equilibrium
$	ext{CO}_2 + 	ext{H}_2	ext{O}
ightleftharpoons 	ext{H}_2	ext{CO}_3$

# Answer:
$\boldsymbol{	ext{CO}_2 + 	ext{H}_2	ext{O}
ightleftharpoons 	ext{H}_2	ext{CO}_3}$

# Brief Explanations:
Both rely on pressure changes to release dissolved CO₂. Lake Nyos had high bottom pressure trapping CO₂; a disturbance reduced pressure, letting CO₂ erupt. A soda can is pressurized to keep CO₂ dissolved; opening it lowers pressure, making CO₂ bubble out.

# Answer:
Both events involve the release of dissolved carbon dioxide due to a sudden drop in pressure:
1.  Lake Nyos: Deep water pressure trapped dissolved CO₂. A disturbance reduced this pressure, causing the CO₂ to erupt from the water into the air.
2.  Soda can: Pressurized gas inside keeps CO₂ dissolved in the liquid. Opening the can lowers the pressure, making CO₂ bubble out of the liquid.

# Brief Explanations:
CO₂ is denser than air, so it settled in low-lying valleys. The traditional practice of building on high ground kept people above the gas cloud that killed valley settlers.

# Answer:
Carbon dioxide is denser than air, so the deadly gas cloud from Lake Nyos flowed downhill and settled in the low-lying valleys where new immigrants had settled. The traditional practice of building houses on high ground would have kept people above this heavy gas cloud, avoiding exposure to the lethal CO₂ and saving more lives.
