Answer:
Maybe later, not right now. Tell you when.
Answer:
1) -COOH
2) -NH2
3) hydrogen bonds
4) dispersion forces
5) -CH3
6) hydrogen bonds
7) negative
8) negative
9) positive
Explanation:
Alanine has a <u>-COOH</u> and a <u>-NH2</u> group available to form <u>hydrogen bonds</u> with water molecules.
Although there are some potential <u>dispersion forces</u> between the terminal <u>-CH3</u> group of alanine and hexane molecules, we expect the <u>hydrogen bonds</u> between alanine and water to be stronger.
Stronger intermolecular attractive forces between alanine and water lead to a more <u>negative ΔHmix</u> and more <u>negative (smaller positive)</u> ΔHsoln for water than for hexane.
Answer:
The answer to your question is given below
Explanation:
From the question given above, the following data were obtained:
Mass of cholesterol (in μg) = 203 μg
Mass of cholesterol (in Kg) =?
The following conversion scale can be used to convert micro grams (μg) to kilogram (kg).
1 μg = 1×10¯⁹ Kg
Therefore,
203 μg = 203 μg × 1×10¯⁹ Kg / 1 μg
203 μg = 2.03×10¯⁷ Kg
Thus, 203 μg is equivalent to 2.03×10¯⁷ Kg
For an atom to be neutral the protons and the electrons should be equal.
Therefore the number of protons are 5
So A is the answer.
6.02x10^23 would be it.
