Which statement best represents a hypothesis? O A. Mosquitoes are attracted to bright lights at night.
O B. If mosquitoes are given a light in a dark room, they will fly toward the light.
O C. Are mosquitoes attracted to bright light or darkness?
O D. I often see mosquitoes near street lamps, so they will prefer bright light.

B

Explanation:

A hypothesis is a proposed explanation for a phenomenon. It is what you think will happen in the experiment.

A is wrong, it is a fact.

C is wrong, it is a question.

D is wrong, it is an observation,

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
