The insertion of extra atoms or molecules into an unsaturated hydrocarbon is called:

The correct answer is an addition reaction.  

A reaction in which two or more reactants come together to produce a single product is called an addition reaction. The product will comprise all the atoms, which were there in the reactants. The addition reaction takes place with unsaturated compounds.  

Hydrohalogenation is one of an example of the addition reaction, in which supplementation of a hydrogen atom and a halogen atom takes place with an unsaturated compound.  

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
