Under each sentence, write the correct formula for each substance, then balance the reaction. REMEMBER THE HEAVENLY SEVEN! Hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine in the gas phase are all diatomic
(all but Brand I are gasses at or around room temperatures) - meaning their formula in an equation will be H, N, O,
F Cl, Br, and is
8) Zinc and copper I sulfate yield zinc sulfate and copper metal

Aglow stick contains a glass vial with chemicals. when the glow stick is bent, the vial breaks and the chemicals react to produce a glow. a science student observes that a glow stick kept in the freezer glows for a longer duration than a glow stick kept at room temperature. what conclusion can be drawn based on the observation? be sure to note the outcome and test variables in the conclusion.
