Yes, because if you are not, there could be an accident if too much of a chemical is added, and when you want to work out the amount of product produced or reactant used, without a large degree of uncertainty, you must be as precise as possible. (The less precise, the more uncertainties, the larger percentage error) But remember, you must be accurate and precise in order to get reliable results. Accuracy is the ability to have your experimental data match up with known results, and precision is the ability to obtain the same data more than once.

A reaction that is the exact opposite of what was therapeutically intended is a paradoxical reaction.
physical change, because the frozen rain can be turned back into rain (or water if you want to be exact) But a good example of a chemical reaction would be, you have the ingredients for a cake, you take those ingredients, mix and bake them, that would be a chemical reaction because it cannot be turned back into a cake
The reactants in a chemical reaction exist before the reaction begins and are consumed during the reaction. Once the reaction is complete, the reactants are typically no longer present. However, in some cases, a small amount of reactant may remain unreacted or there may be reversible reactions where some reactants can be regenerated.
Hemoglobin is a globular protein, an natural organic polymer. It does an exact formula, but this is far too complicated . The emperical formula is C738H1166N812O203S2Fe It is built up of amino acids with a Iron ion in the Nucleus.

It is important to know the exact formula of a chemical compound.
Coefficients are imortant in a balanced chemical reaction, because it shows you how much of that chemical is reactanting, and also how much is being produce to form the products.
Items like H2O and CoC2 have a definite chemical composition, and require exact amount of particles to forma reaction. However; particles which are soluble in water do not have a definite chemical reaction.
A reaction that is the exact opposite of what was therapeutically intended is a paradoxical reaction.
A balanced chemical reaction obeys the law of conservation of mass, because the same number of atoms of each element must appear on both sides of the equation for the reaction, and in any actual reaction, the same exact atoms will be found on both sides of the equation.

To get an exact answer, you would have to specify a fusion reaction; different reactions will produce different amounts of energy. However, to get a rough idea, the energy produced is in the order of a million times more than the typical chemical reaction.
It is important to balance the equation, so that you know the exact ratio of reactants required and products formed. If you don't consult a balanced equation, some of your reactant may not completely consume in reaction or sufficient product is not formed during experiments.
Chemical equilibrium is a term used to describe a balanced condition within a system of chemical reactions. Essentially, when in chemical equilibrium, substances becomes definite and constant.

The dose makes the poison. Both are harmful above certain levels. The exact chemical form is also important.
