How much fat or calories is in a pint of chicken and broccoli with white rice? A small amount of fat, but it's the good kind, medically speaking. Skinless chicken meat (again, typically used in stir-fry) is fairly low-fat, and 1 cup of cooked chicken contains about 200-250 calories (sorry, I'm not a calorie-counter myself). A cup of cooked white rice is about 200 calories, as well. And of course, the broccoli is pretty healthy all by itself. The only way to know for sure is to ask at the restaurant (what type of oil they use, whether the chicken is skinless, etc).

reaction A rearrangement of the atoms or molecules of two or more substances that come into contact with each other, resulting in the formation of one or more new substances. Chemical reactions are caused by electrons of one substance interacting with those of another. The reaction of an acid with a base, for example, results in the creation of a salt and water. Some, but not all, reactions can be reversed.

Nuclear chain reaction Nuclear chain reactions are series of nuclear fissions (splitting of atomic nuclei), each initiated by a neutron produced in a preceding fission. For example, 2 1 / 2 neutrons on the average are released by the fission of each uranium-235 nucleus that absorbs a low-energy neutron.

- A synthesis reaction is a type of reaction in which multiple reactants combine to form a single product. Synthesis reactions release energy in the form of heat and light, so they are exothermic. An example of a synthesis reaction is the formation of water from hydrogen and oxygen. Synthesis is, in essence, the reversal of a decomposition reaction. synthesis reaction combination.
