Answer: 33.3 moles
Explanation: 67.2 g H2 = 67.2/2.016 = 33.3 moles
Answer:
V2 = 3.11 x 105 liters
Explanation:
Initial Volume, V1 = 2.16 x 105 liters
Initial Temperature, T1 = 295 K
Final Temperature, T2 = 425 K
Final Volume, V2 = ?
These quantities are related by charle's law and the equation of the law is given as;
V1 / T1 = V2 / T2
V2 = T2 * V1 / T1
V2 = 425 * 2.16 x 105 / 295
V2 = 3.11 x 105 liters
Answer:
Both involve drilling into the earth and can cause environmental degradation.
Explanation:
Based on temperature changes, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.
<h3>What is change of state?</h3>
Change of state is the process whereby a substance changes its state of matter from one form to another as as result of heat changes.
In the graph shown above, water exists in three states at different points.
- Water exists as a solid at A
- Water exists as a liquid at B
- Water exists as a gas at C.
Therefore, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.
