I would say letter C.
"the oxygen atom<span> attracts </span>electrons<span> a bit </span>more<span> strongly </span>than the hydrogen atoms. The unequal sharing of electrons<span> gives the </span>water<span> molecule a slight </span>negative charge<span> near its </span>oxygen atom <span>and a slight </span>positive charge<span> near its </span>hydrogen atoms<span>." (middleschoolchemistry.com)</span>
It can bond with another atom to gain 3 more valence electrons (-3)
Answer:
Q=msΔT
rearranging in terms of temperature gives:
ΔT=Q/ms
=1320j/(230g×0.338(j/g°C))
=16.97967584°C
=> ΔT=17.0°C
Ethers can't form hydrogen bonds with water and so have a low solubility
hope that helps
