Please add a picture of what numbers ; )
Explanation:
element with atomic numbers 7 and 83 have 5 and 5 valence electrons
12 times breathe give 240 ml of pure 
. Each breathe gives 20 ml of .
Let us consider, volume of air per breathe= x ml.
Pure from inhaled air= 
ml and Pure from exhaled air= 
ml.
Pure from inhaled and exhaled air= 20 ml
So, + = 20
Therefore, x = 55.5 ml
So, volume of air per breath= 55.5 ml.
The answer is B. Molecules move more quickly as temperature increases.
When Allmond molecular motion stops, that is considered absolute zero. That does not mean that it cannot get colder, disapproving A.
C is just wrong.
D says when molecular motion stops the temperature STARTS to decrease, it was decreasing before it got there.
