In nutrition, certain foods have an acidic effect on the body after consumption, and certain foods have an alkaline effect. Plant foods, such as ginger, are the most alkaline-promoting foods. Ginger has a pH of 5.6 to 5.9, similar to that of figs, fennel, leeks, parsnips and romaine lettuce.
The reaction between aluminum and bromine is very exothermic (DH o = -1022 kJ). This drives the entire process, and energy is given off in the form of light and heat: 2 Al (s) + 3 Br 2 (l) --> 2 AlBr 3 (s) The product of this reaction is a molecular solid with the formula Al 2 Br 6, but the formula is often written as AlBr 3.
Alkanes can react with halogens in the presence of UV light. During this reaction, halogen atoms substitute for (replace) hydrogen atoms, one at a time, producing a haloalkane and a hydrogen halide. Further substitutions are possible.Alkenes readily react with halogens under standard laboratory conditions.lkanes can react with halogens in the presence of UV light.
