When a tortilla alone can run you 300 calories, and a dollop of sour cream about 115, staying under 1000 can be challenging (forget about adding chips and guacamole). The Times found that just 25 out of 1,200 burritos fell below 700 calories.
the hydrogen atom attracts electrons much more strongly than the oxygen atom. water has two hydrogen atoms covalently bonded to a single oxygen atom. the oxygen atom has a greater attraction for electrons than the hydrogen atom does. water dipole moment is equal to zero. the electrons of the covalent bond are not shared equally between the hydrogen and oxygen atoms.
Share to: Those compounds which has partial positive and partial negative ends due to electronegative difference and there dnet dipole moment is not zero.for example: HCl,water.O is polar. If you compare the electronegativities (how strongly the element pulls on electrons) N 3.04 O 3.44 (bigger therefore pulls electrons harder) The electron â¦ s will be drawn to the oxygen causing it to be slightly negative, and the N to be slightly positive.
