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.
The Activation Energy of Chemical Reactions Only a small fraction of the collisions between reactant molecules convert the reactants into the products of the reaction. This can be understood by turning, once again, to the reaction between ClNO 2 and NO.
