Answer: 13 liters
Explanation: It is crucial to remember two factors that allow us to carry out this calculation.
Firstly, temperature and pressure must remain unchanged, so these constant values are not considered when calculating volume since they will always be the same.
Secondly, we are dealing with the same gas, with the conditions remaining consistent. Hence, we can proceed.
For 1.2 moles of gas, we have a volume of 8.5 liters. Now, let's determine the volume for 0.65 moles:
0.65 mole * (8.5 liter / 1.2 mole) = 4.25 liters
As we maintain the same gas type, we simply need to total the volumes for each mole amount:
8.5 liters + 4.25 liters = 12.75 liters, which rounds to 13 liters.
Answer:
A balloon will hold a gas volume of 45.0 L at a pressure of 1.35 atm and a temperature of 253 K.
Explanation:
Applying the Ideal Gas Law for the same gas amount, we have:

Parameters are given as follows:
V₁ = 25.0 L
V₂ =?
P₁ = 2575 mm Hg
To convert pressure to atmospheres: P (atm) = P (mm Hg) / 760
P₁ = 2575 / 760 atm = 3.39 atm
P₂ = 1.35 atm
T₁ = 353 K
T₂ = 253 K
Using the earlier formula, we derive:



By solving for V₂, we find:
V₂ = 45.0 L
A balloon will hold a gas volume of 45.0 L at a pressure of 1.35 atm and a temperature of 253 K.
A heavier player collides with a lighter player using greater force.
The lighter player sustains more injuries following the impact.
Explanation:
A heavier player impacts a lighter player with greater intensity, resulting in more pronounced injuries to the lighter player post-collision.
Force is defined as mass multiplied by the acceleration of an object;
Force = mass x acceleration
We observe that as mass and acceleration increase, the force exerted rises accordingly.
Clearly, the heavier player's mass surpasses that of the lighter player, leading to a greater force exerted upon collision.
Moreover, the lighter player is likely to be injured more severely after the clash. The momentum generated by the heavier player during the impact is considerably significant. Once they collide, the lighter player will certainly alter their speed and trajectory.

Response:
a. To purify a gypsum sample, you will need the following equipment: Bunsen burner, beaker, filter funnel, stirring rod, and filter paper.
b. Gypsum, a sulfate mineral consisting of calcium sulfate dihydrate, can be purified by following these steps:
1. Add water to the gypsum in a beaker.
2. Stir the mixture thoroughly with the stirring rod.
3. Use the filter paper and filter funnel to remove excess solids from the mixture.
4. Heat the filtered mixture on the Bunsen burner to evaporate the remaining water.
5. After cooling, filter again through the filter paper to obtain pure gypsum.
