Explanation:
Antoine equation is as follows.
It water is at , then values of constants A, B, and C will be as follows.
A = 8.07131, B = 1730.63, C = 233.426
When pressure, P = 2.5 atm then putting these given values into the above equation as follows.
5.40365 =
T =
Converting the temperature into Fahrenheit as follows.
=
=
Thus, we can conclude that the boiling temperature of the water is .
Answer:
III. Fatty acids are less oxidized than carbohydrates
Explanation:
Both triglycerides and glycogen may be used to obtain energy, this is:
- Triglycerides through the B-oxidation, where a molecule is first activated and entered into mitochondria matrix, to be degraded (oxidized)
- Glycolysis, where a molecule of 6 carbons is splitted in 2 components of 3 carbons each (pyruvate)
As an energy reserve substance, triglycerides have 2 main advantages, compared with glycogen:
1) From the chemical point of view, triglycerides have a more reduced state than glycogen (this is, have more atoms of hydrogens), hence these molecules give twice energy than glycogen
2) As triglycerides are hydrophobic molecules, they remain in an anhydrous form (unlike glycogen, which is hydrophilic), and this makes easier to move these molecules to obtain energy
The addition of heat energy to a
system always causes the temperature of that system to increase. This is always
true because you are adding heat of a substance to increase its temperature. For example, you are going
to drink a cup of coffee. And you wanted it hot to boost your attention. So you
have to use hot water. In order for your water to become hot or warm, you need
boil it in a kettle. Note that you are going to use an electric stove. The
electric stove gets it energy from the source giving it a hotter temperature to
the water in the kettle. You are applying heat energy to warm the water. So,
the statement is true.
Argon has 8 valence electrons. It's atomic number is 18, therefore, in the first shell there are 2, the second has 8 and the third also has eight.
