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.
Because the dipole moment of acetone (2.88 D), and thus its polarity, is actually larger than that of water (1.85 D), one might even expect that LiCl would be more soluble in acetone than in water. In fact, the opposite is true: 83 g of LiCl dissolve in 100 mL of water at 20Â°C, but only about 4.1 g of LiCl dissolve in 100 mL of acetone.
