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.
To balance the chemical equation above, we need to make use of coefficients. A coefficient is a number that we place in front of a chemical formula. In the chemical equation, to make the number of nitrogen (N) atoms equal on both sides, first, we place a coefficient of 2 in front of NH3. Once we do that, the number of nitrogen (N) atoms on both sides is balanced.
