One point that is not true is an electron orbital has the same amount of energy in all orbital.
hope this helps!
Answer:
Moisture content in wet basis = 47.4 %
Explanation:
<u>Moisture content expresses the amount of water present in a moist sample.</u> <u>Dry basis and wet basis are widely used to express moisture content. </u>
The next equation express the moisture content in wet basis:
<em>where, : moisture content in wet basis and </em>
<em> : moisture content in dry basis </em>
We now calculate the moisture content in wet basis:
= 0.474 = 47.4 % wet basis
Have a nice day!
Answer: The boiling point of water is an absolute constant
Explanation:
The boiling point of a compound is NOT an absolute constant. This is because at certain conditions such as a change in altitude, the boiling point of a compound changes.
As temperature increases, evaporation increases and vapour pressure increases. Compounds boils when vapour pressure equal to the atmospheric pressure.
At higher altitudes, atmospheric pressure is decreses.
When atmospheric pressure is decresed, the vapour pressure of the compound is lowered to reach boiling point. Therefore, the temperature needed for vapour pressure to equal atmospheric pressure is lower. The boiling point is lower at higher altitude.
Hence boiling point depends on atmospheric pressure
Answer:
100 °C, because it is the boiling point of water.
