A 200 kg object accelerates at a rate of 5.5 m/s2 calculate the force required to produce this acceleration.

Explanation:

F=ma

m=200 Kg

a=5.5 m/s2

F=ma

F=200*5.5 =1100 N

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

the answer is b. dilution
