The reaction 2fe + 3cl2 → 2fecl3 is an example of which type of reaction?
combustion reaction
single-replacement reaction
combination reaction
decomposition reaction

combination reaction

Explanation:

In a combination reaction two reactants combine to form a single product, like in  this case.

Other options are incorrect because:

a polar bond is formed when electrons are shared unevenly between atoms

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.
