The resulting pressure of the gas after decreasing the initial volume is 3 atm.
<h3>What is
Boyle's Law?</h3>
According to the Boyle's Law at constant temperature, pressure of the gas is inversely proportional to the volume of the gas:
P ∝ 1/V
For the given question required equation is:
P₁V₁ = P₂V₂, where
P₁ = initial pressure = 1.5 atm
V₁ = initial volume = 2 L
P₂ = final pressure = ?
V₂ = final volume = 1 L
On putting all these values on the above equation, we get
P₂ = (1.5)(2) / (1) = 3atm
Hence required pressure is 3 atm.

Answer:
No, it is not balanced.
The balanced equation is: Zn(OH)₂ + 2NaOH → Na₂ZnO₂ + 2H₂O.
Explanation:
- To balance the equation, you should apply the law of conservation of mass for the equations.
- The law of conservation of mass states that the no. of each atom is equal in both sides (reactants and products).
- For the given equation: <em>Zn(OH)₂ + NaOH → Na₂ZnO₂ + H₂O.</em>
The no. of Na atoms in reactants side is 1 but in products side is 2.
The no. of H atoms in reactants side is 3 but in product side is 2.
<em>So, the equation is not balanced.</em>
<em></em>
- The balanced equation is:
<em>Zn(OH)₂ + 2NaOH → Na₂ZnO₂ + 2H₂O.</em>
<em></em>
- The no. of all atoms is the same in both of reactants and products side.
Zn (1), O (4), H (4), and Na (2).
