Weak Bonds
These bases contain Nitrogen and these create a twofold strand of DNA through not so strong hydrogen bonds. The nitrogen bases, notwithstanding, have particular shapes and hydrogen bond properties so guanine and cytosine just bond with each other, while adenine and thymine additionally bond only. This matching off of the nitrogen bases is called complementarity. All together for hydrogen clinging to happen by any means, a hydrogen bond benefactor must have a corresponding hydrogen bond acceptor in the base opposite it.
The appropriate answer is c. the solid phase, liquid phase and gas phase of a substance. A phase diagram is used to represent the phase or physical state of a substance at a given temperature or pressure. Pressure is represented on the y axis while temperature is represented on the x axis. Phase diagrams are used in areas such as Physics, Chemistry, Engineering, Mineralogy and Material Science.

Answer:
C3H6
Explanation:
We can obtain the molecular formula by using the empirical formula and the molar mass in combination.
This is shown below:
[CH2]n = 42g/mol
We then add the atomic masses of carbon and hydrogen and multiply by n to give the value of n .
n[12 + 2(1)] = 42
14n = 42
n = 42/14 = 3
The molecular formula is thus [CH2]3 = C3H6
Hydrogen gas is H2, so it is not an atom, it is a molecule.
