Which of the following water molecules exists in the greatest abundance?

a. d217o

b. h218o

c. t218o

d. h216o

e. d216o

f. t217o

d. H216O

Explanation:

Hello,

Water is a chemical compound which has two hydrogen atoms and one oxygen atom.In solid state, it is ice where as in gas state, it is steam.Hydrogen and oxygen atoms in water molecule form polar covalent bonds formed through hydrogen bonding. Oxygen has three isotopes to remember ; H2160, H2180 and H2170. Sea water for example has approximately 99% H2160 and less than 0.5% H2180.

Evaporating waters releases more H2160 to the atmosphere than H2180.In areas where polar ice takes time to melt, the oceans are contantly depleted of H2160 until it melts to return to the water bodies and maintain balance.This shows that the water molecules that exists in greatest abundance is H2160.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
