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.
An important feature of water is its polar nature. The water molecule forms an angle, with hydrogen atoms at the tips and oxygen at the vertex. Since oxygen has a higher electronegativity than hydrogen, The side of the molecule with the oxygen atom has a partial negative charge. A molecule with such a charge difference is called a dipole.
