What is the best safety approach when working with unknown chemical substances? Select one: Assume that any substance distributed to lab participants is non-toxic and not a safety risk. Read the procedure and try to guess what the unknown substance is, then review its specific safety information. Assume that the substance is hazardous. Always wear appropriate PPE and take steps to prevent contact. Do not begin working with a substance unless you know exactly what it is.

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?
