When the KClO3 decomposes, more oxygen is produced. I don't think I know any other possibility exists.<span />
First, we distinguish whether table sugar or table salt will be more soluble. The bonds between the molecules of the table sugar are weaker than the bonds between the molecules of salt. Therefore, it is easier for the sugar molecules to dissolve.
Next, we evaluate the effect of temperature on solubility. As the temperature of a solvent increases, it is able to hold more and more solute. This means that the sample with table sugar kept at the highest temperature will contain the most dissolved solute, and this is sample 1.
Explanation:
It is given that the initial mass of benznene is 7.9286 g
Mass of benzene left = 5.9987 g
So, mass of benzene with which gas get saturated will be calculated as follows.
= 7.9286 g - 5.9987 g = 1.9299 g
Therefore, moles of benzene with which gas get saturated = 
= 
= 0.0247 moles
Temperature = 
= 27.3 + 273.15 = 300.45 K
Volume = 5.01 L
So, according to ideal gas equation PV = nRT
Putting the given values into the ideal gas equation as follows.
PV = nRT
= 
P = 
= 92.371 torr
Hence, we can conclude that vapor pressure of benzene is 92.371 torr.
A pH of 7 is neutral, because a measure of acidity or alkalinity of water soluble substances (pH stands for 'potential of Hydrogen'). A pH value is a number from 1 to 14, with 7 as the middle (neutral) point.
Answer:
The enthalpy of vaporization of H2O is higher than the enthalpy of fusion of H2O, therefore vaporizing the same mass of H2O would require more heat/energy than melting the same mass of H2O.
hope it helps!
