The answer is HCl, C3H6 and C2H5OH. Hydrochloric acid has the lowest boiling point among the three choices since it only has weak dipole-dipole and Van der Waal's forces between molecules which are much weaker than the forces of attraction present in propane and ethanol. Ethanol has the highest since the hydrogen bonding present in ethanol make it hard to break the bonds.
If you look at the equation for photosynthesis, it is:
<span>6CO2 + 6H2O + light energy ---> C6H12O6 + 6O2
</span>
Since CO2 (carbon dioxide) is on the left side of the equation, it is being consumed, or used up. Since O2 (oxygen) is on the right side, it is being produced.
The correct answer is the first one, "<span>Carbon dioxide is used up, and oxygen is produced."</span>
Answer:
It is a group of compound derived from alkanes containing one or more halogens .
Answer: A. The compound CuCl is 500 times less soluble in sea water than it is in pure water.
pure water.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in a equilibrium reaction, the equilibrium will shift in a direction so as to minimize the effect.
Thus when a common ion is introduced to an equilibrium reaction, the equilibrium will shift in a direction where the concentration of common ion is decreasing.
When common ion such as 
from NaCl in sea water is introduced to an equilibrium reaction, the equilibrium will shift in a direction where the concentration of common ion is decreasing i.e. in the left side and thus solubility of CuCl further decreases.
