However, some lab coats can be classified as PPE, therefore prohibiting them outside of the work area, according to the OSHA bloodborne pathogens standard 1910.1030(d)(3)(vii). From a safety and infection control standpoint, it only makes sense to contain infections and germs as much as possible. Some labs have employees wear one coat for the work area (considered PPE) and another in a different color, which can be worn outside of the lab â mostly for warmth â in places like the cafeteria.
What is the importance of the coefficients in a balanced chemical reaction? coefficients are important to prove the law of conservation of mass. The coefficients in a balanced chemical equation indicate the relative number of moles of reactants and products. From this information, the components of reactants and products can be calculated.
Once all quantities have been converted to moles and you have a balanced reaction, you are ready to actually use stoichiometry. The idea of stoichiometry is really quite simple. The coefficients (or numbers) in front of each reactant and product in the balanced chemical reaction tells you the ratio of how much of each you will react/produce.
