Suppose you a 2 of 10M solution and poured 4 liters of water into it. What would be the new concentration of the solution?

3.33M

Explanation:

M1V1=M2V2

M1 = 10M

V1=2L

V2=6L

M2 = M1V1/V2 = 10x 2/6 = 3.33 M

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
