A covalent bond describes two atoms (most likely nonmetals) that share their valence electrons to satisfy the octet rule. Carbon and oxygen are both nonmetals, and they would share electrons with each other through a bond that is not polar enough to be considered ionic. The answer should be B
Answer:
The boy is using kinetic energy. And his joules are 60
Hello!
By law of Dalton’s partial pressure the sum of the partial pressures is the total of all the pressures. So if the total is 740mm Hg then 740=400+200+x
so solving for x the unknown pressure we get 740-600=140mm Hg.
Hope this helps! Any questions please just ask! Thank you so much!
Your question isn't quite clear, but if you're wondering if a chemical is polar or non-polar, you simply draw a VSEPR sketch and draw arrows where the bonds are. Only draw arrows between atoms, NOT between an atom and a lone pair of electrons. The arrow should point to the most electronegative atom (you should be given an electronegativity scale). Afterwards, you add up the arrows as vectors, and look at the sum of the vectors. If the sum is zero (CH4 is a good example), the chemical is non-polar. If the sum is a vector, the chemical is polar (H2O, or water, is polar).
