Answer:
B.nitrogen
Explanation:
Nitrogen is a gas at room temperature.
>there is restricted rotation around the carbon-carbon double bond. (TRUE)
>the stability of the carbon-carbon double bond increases as the
number of substituent groups increases. (TRUE)
>whenever the two groups on each end of a carbon-carbon double bond
are the same, two diastereomers are possible. (TRUE)
>trans alkenes are generally more stable than cis alkenes. (NOT TRUE)
When gasses are heated they emit only certain wavelengths of light (an emission line spectrum). Different gasses emit different wavelengths. A cool object (gas or solid) can absorb some of the light passing through it. The temperature of an object is a measure of how much energy its atoms have.

The decay curve is a graph showing the relationship of the amount of a substance like Phosphorus-32 with respect to time. Through time, the amount decreases. If the curve was given, you will just have to locate the half of the original amount in the y-axis and connect it to the curve. Then, you move it downwards to the x-axis to determine the time. The time at which the amount of Phosphorus-32 left is reduced to half is called the half-life.
But this have been experimented and there is already an empirical value for this. The half-life of Phosphorus-32 is 14.29 days.
