Catalytic converters on cars transform toxic exhaust gases such as carbon monoxide and nitrogen oxides into less toxic gases such as carbon dioxide and nitrogen. One of the greatest health benefits of catalytic converters was to nearly eliminate air pollution from a neurotoxic chécmical. This chemical, which had been previously added to gasoline, had to be eliminated since it destroyed the catalytic converters. What was this chemical?

There are different types of food coloring available in most grocery stores- one that is water-based, and one that is oil-based. The oil-based food coloring works best in chocolates, in fry-oil to color fried foods, and in food with high butter contents. Based off of this information and knowing that substances of like polarity mix readily with one another, which food coloring is more polar (water-based or oil-based)? Which food coloring is less polar (or even nonpolar)? Water-based [Choose ]
