What negative impact did chemistry have on society through the production and use of chlorofluorocarbons (CFCs)? Hazardous coolants in refrigeration units were replaced.
Better refrigeration reduced loss of food through spoilage.
Lower levels of ozone allowed more ultraviolet radiation to reach Earth.
Fire safety improved through the use of fire extinguishers.

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
