What chemical is sprayed on apples to keep them form turning brown?
Q. I love that McDonald's has some more healthy snack selections. In particular I enjoy the fruit and walnut salad. I know that they must spray some type of chemical to keep the apples from turning brown. I bought a pack today 11/16 they will be considered edible until 11/28... That sounds chemically modified to me.

A. The apples might have been soak in a water & lemon juice mixture, or anti- browning solution made with Vitimin C ( Ascorbic acid ) which is added to many foods not just for it nutritive value, but extensively as an anti-oxidant, and to prevent flavors and colors from being damaged by oxidation. It is widely used used in canned and frozen fruits to prevent the browning that accompanies oxidation.

A. Polar bones are found in polar bears. The most polar bonds have the greatest electronegativity difference. H-S -- 2.58 - 2.20 = 0.38 C-S -- 2.58 - 2.55 = 0.03 ** most non-polar bonds P-F -- 3.98 - 2.19 = 1.79 ** most polar I-Br -- 2.96 - 2.66 = 0.30
