>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)
Answer:
4
Explanation:
I dont know that's all you need
Evaporation!
-Melting is a solid to a liquid
-sublimation is directly from a solid to a gas
-condensation gas to liquid
Answer:
a. ΔΗ > 0, solution feels cold
Explanation:
Hello,
In this case, endothermic process are those in which we can find that the products have more energy than the reactants, therefore energy is absorbed, for which the following equation:
Must be greater than 0 (positive) thereby, for a solution process we find that the solution feels cold, in such a way, answer is a. ΔΗ > 0, solution feels cold.
Regards.
