Answer:
newtons 2nd law is the answer
Water combines with carbon dioxide to produce slightly acidic groundwater
that dissolves limestone and forms caves.
This is because the reaction between water and carbondioxide to form
bicarbonate ions( HCO₃⁻). The bicarbonate ions dissociate into Hydrogen
atoms thereby increasing the acidity.
The acidic environment results in the formation of acidic groundwater that
dissolves limestone and forms caves.

Answer:
n₂ = 0.2 mol
Explanation:
Given data:
Volume of 1st balloon = 2.5 L
Moles of He in 1st balloon = 0.100 mol
Volume of second balloon = 5.0 L
Moles in second balloon = ?
Solution:
According to the Avogadro law,
Number of moles of gas is directly proportional to the volume of gas at constant temperature and pressure.
Mathematical expression:
V₁/n₁ = V₂/n₂
V₁ = Volume of 1st balloon
n₁ = Moles of He in 1st balloon
V₂ = Volume of second balloon
n₂ = Moles in second balloon
Now we will put the values.
2.5 L / 0.100 mol = 5 L /n₂
n₂ = 5 L× 0.100 mol /2.5 L
n₂ = 0.5 mol /2.5
n₂ = 0.2 mol
