X, Y and Z are three hydrocarbons. X CH2=CH2 Y CH3–CH=CH2 Z CH3–CH2–CH=CH2

What do compounds X, Y and Z have in common?

1. They are all alkenes.

2. They are all part of the same homologous series.

3. They all have the same boiling point.

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
