A. is right because the waves are at the top and as u get deper of course the energy will decrease
Try looking this stuff on Google ITS GREAT!!
True:
They are Nobel gassed! They are un-reactive because there outer shell (valence) is completely full. This means they do not want to lose or gain on electron so they do not react.
The pressure of the oxygen gas collected : 718 mmHg
<h3>Further explanation</h3>
Given
P tot = 748 mmHg
P water vapour = 30 mmHg
Required
P Oxygen
Solution
Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
Can be formulated:
P tot = P1 + P2 + P3 ....
The partial pressure is the pressure of each gas in a mixture
P tot = P H₂O + P Oxygen
P Oxygen = 748 mmHg - 30 mmHg
P Oxygen = 718 mmHg
Answer:
A condensation reaction
Explanation:
it is also called a dehydration reaction
