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.
Just like we want the scale to be balanced on both sides, a chemical equation should also be balanced on both sides. A chemical equation shows us the substances involved in a chemical reaction-the substances that react (reactants) and the substances that are produced (products).owever, the number of hydrogen (H) atoms is not balanced on both sides. We need to make use of another coefficient in front of H2. This time, we put a coefficient of 3 in front of H2 to balance the chemical equation. The equation above is now balanced.
