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.
The solubility product constant, K_(sp), which is essentially a measure of the degree of dissociation of zinc hydroxide in water, is equal to 3.0 * 10^(-16) at room temperature. https://en.wikipedia.org/wiki/Zinc_hydroxide This basically tells you that the electrostatic attraction that exists between the zinc cations and the hydroxide anions far exceeds the attraction between the polar water molecules and the two ions -> zinc hydroxide is considered insoluble in aqueous solution.
