Which of the following statements is consistent with the particle diagram below?
Before reaction
has started
After reaction
is completed
The reaction produces six molecules of the product
because time was stopped before the reaction was
completed
The reaction produces six molecules of the product
because the reaction is inefficient.
The reaction produces six molecules of the product
because the open circled atoms are limiting its
production
The reaction produces six molecules of the product
because the dark circled atoms are limiting its
production

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
