Answer:
Because , the advantage of steam distillation over simple distillation is that the lower boiling point reduces decomposition of temperature-sensitive compounds. Steam distillation is useful for the purification of organic compounds, although vacuum distillation is more common
Explanation:
Answer:
The answer to the question is
The source of the nitro- gen and oxygen atoms is from the atmosphere
Explanation:
When gasoline burns oxygen from the atmosphere supports the combustion reaction.
For example the internal combustion engine of a motor vehicle pulls in air from the surrounding atmosphere to make use of the oxygen in aiding the combustion of the gasoline to drive the pistons that ultimately moves the vehicle. The air from which the oxygen is absorbed also contains more amount of Nitrogen by percentage than oxygen. The nitrogen therefore enters into the combustion reaction that eventually produces nitrogen oxide and nitrogen dioxide
Answer:
The answer is a carbon isotope.
Explanation:
Carbon has 6 protons and electrons so the atom is neutral.
However it is a carbon isotope because it has more neutrons than protons so be aware of that
<span>Temperature causes water molecules to move more quickly, because each individual molecule has more energy as it gets hotter .
So, the answer is A.

The melting points of the compounds from the choices are listed below:
a. C25H52 -> +47 to +56 degrees celsius
b. Hg -> -38.83 degrees celsius
c. CaCl2 -> +772 degrees celsius
d. CuO -> +1326 degrees celsius
It is evident from the listed melting points above that mercury (Hg) has the lowest melting point. This is why mercury is liquid at room temperature.
