Answer: Option 1 and 11
1. Organic solvents are often flammable.
II. Organic solvents are often toxic.
Explanation:
Organic solvents are often flammable and Organic solvents are often toxic are the reasons why organic chemistry is a primary target of green chemistry because green chemistry is the use of principles or approach to remove hazardous or toxic substances from chemical.profuctd or processes to make them fit or safe for use and the solvents of organic chemist are toxic, therefore green chemistry remove the toxic substances.
The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension<span>. I think the correct answer is option A. H2O will have the highest surface tension due to the hydrogen bonds that are present. Hope this answers the question. Have a nice day.</span>

Answer:
9.28
Explanation:
pOH refers to a measure of hydroxide ions concentration. pOH tells about the alkalinity of a solution. If pOH is less than 7 then aqueous solutions are alkaline, acidic if pOH is greater than 7 and neutral if pOH is equal to 7.
Concentration of the hydroxide ions = 1.9 x 10-5 M
pH = 
pOH = 14 - pH
=14 - 4.72 = 9.28
