Explanation:
The teacher is most likely talking about the fractional distillation process.
Fractional distillation: It is a separation technique used to separate different components of the given mixture on the basis of their difference in boiling points of the different components. The component with lowest boiling point will get separate out first from the mixture and the vapors formed from boiling are condensed in a separate container.
So, when the fractional distillation of mixture of oils and fuels is carried out gasoline will separate out first due to lower boiling temperature and then kerosene followed by diesel and others (fuels and oils).
Answer:
distillation of a mixture
Explanation:
a. chromium (III) chloride
c. monochromium trichloride
b. chromium chlorine
d. chromium(III)trichloride
Answer:
a. chromium (III) chloride
Explanation:
Chromium chloride is also binary ionic compound composed of only two element chromium and chlorine.
When naming these compounds the name of metal or cation is written first and anion is written after the cation. The anions are non meals.
The anion name is end with suffix " ide".
such as chromium chloride.
The (III) shows the oxidation number of metal. In given compound the oxidation state of chromium is +3 while chlorine chow the oxidation state of -1 that's why three chlorine atoms are attached with one chromium atom.
O ice at 0°C
O liquid water at 90°C
O steam at 100°C
The average kinetic energy of water molecules is greatest in steam at 100°C.
Water is a polar solvent that has potential energy on its own which can be converted to kinetic energy once the water is in motion.
The kinetic energy is that energy that a moving body possesses.The faster a molecule moves, the more kinetic energy it has, and the higher the measured temperature.
That being said, when the temperature of water is increased, there would be increased molecular motion leading to a higher kinetic energy.
Therefore, the average kinetic energy of water molecules is greatest in steam at 100°C.

Answer: C
Explanation:
Velocity is displacement over change in time. It’s a vector quantity, so velocity must include direction. You’re changing the direction, but the speed stays the same, because you are still going 20 km per hr
