<h3>Answer:</h3>
The New pressure (750 mmHg) is greater than the original pressure (500 mmHg) hence, the new volume (6.0 mL) is smaller than the original volume (9.0 mL).
<h3>Solution:</h3>
According to Boyle's Law, " <em>The Volume of a given mass of gas at constant temperature is inversely proportional to the applied Pressure</em>". Mathematically, the initial and final states of gas are given as,
P₁ V₁ = P₂ V₂ ----------- (1)
Data Given;
P₁ = 500 mmHg
V₁ = 9.0 mL
P₂ = 750 mmHg
V₂ = ??
Solving equation 1 for V₂,
V₂ = P₁ V₁ / P₂
Putting values,
V₂ = (500 mmHg × 9.0 mL) ÷ 750 mmHg
V₂ = 6.0 mL
<h3>Result:</h3>
The New pressure (750 mmHg) is greater than the original pressure (500 mmHg) hence, the new volume (6.0 mL) is smaller than the original volume (9.0 mL).
The pillows because it is larger than paperback books, in this situation just think about which is larger, I pretty sure Andre is not going to hold the boxes in his hand.

Answer:
Correct option -D
Explanation:
Here, A kinetics experiment is set up is set up to collect the gas that is generated from the cacarbonate and methanoic acid.
Among the given conditions, decreasing the particle size of calcium carbonate only increases the production of gas.
Smaller particles of reactant increases the surface area then followed by rate of reaction will be increases it leads to increases the production of gas.
Therefore, the suitable experimental condition most likely to increase the gas production is-
Decreasing the particle size of the 
by grinding it into a fine powder.
Hence, correct option -D.
