The correct answer is:
D) a chemical change produces a new substance by breaking and forming new bonds
Carbohydrates & Lipids.
Carbs are organic compounds (examples are sugars & starches). They provide energy and form structures such as cell walls.
Lipids are organic compounds (examples are fats & oils). They store energy and help form cell membranes in addition to having other functions in organisms
<span>A polymer is made of more monomers
Amino acid is a monomer.
When you have more amino acids, it's a polymer (a protein)
So the answer is amino acid
the other 3 are polymers</span>
Answer:
C
Explanation:
Charles law states that volume of gas is directly proportional to temperature at constant pressure
V/T = k
where V - volume , T - temperature and k - constant
\frac{V1}{T1} = \frac{V2}{T2}
T1
V1
=
T2
V2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
in the question it states that the temperature has been increased from 278 K to 231 K but it should actually be temperature is decreased from 278 K to 308 K
substituting the values in the equation
\frac{417cm^{3} }{278K} = \frac{V}{308 K}
278K
417cm
3
=
308K
V
V = 462 cm³
the answer should be C. 462 cm³
The electron orbits the nucleus so your answer would be C.
