Explanation:
<h2>Answer:</h2>
Option 3 is correct.
3. The molecular collisions are perfectly elastic.
<h2>Explanation:</h2>
According to the kinetic molecular theory, the molecular collisions are perfectly elastic, so the the molecules of a gas striking with the wall of container are elastic and they are exerting considerable pressure on the walls of container. This pressure is actually exerted against the walls is less for real gases as compared to ideal gases.
Answer:
22.715 moles of oxygen are used
Explanation:
Given data:
Number of moles of ethane = 6.49 mol
Number of moles of O₂ required = ?
Solution:
Chemical equation:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
Now we will compare the moles of oxygen with ethane.
C₂H₆ : O₂
2 : 7
6.49 : 7/2×6.49 = 22.715 mol
Thus, 22.715 moles of oxygen are used.
I would definitely say that the answer is
C. drought
because if they are getting 43.76 inches of rain on average, and then one year they decrease 10.31 inches of rain to 33.45 inches of rain, its a drought for sure.
