Experience teaches us that most solids are more soluble in warm water than in cold water. Does the solid utility of Mg(OH)_2 fit this pattern? Briefly explain. Cobalt chloride is used in many weather-forecasting devices. Based on your observations in the laboratory, explain how an alcohol solution of CoCl_2 could be used to predict rain. A student is studying the equilibrium described by the net ionic equation shown in Equation 18. [Cu(H_2O)_6]^2+ (aq, blue) + 4 Br^-(aq) CuBr_4^2+(aq, green) +...
10. When sodium chloride dissolves in water, the ions dissociate: NaCl (s) = Na+ (aq) + Cl- (aq) Write ionic equations, similar to the one above, that describe how NaNO3 and NaCH3CO2 each dissociate as they dissolve in water. Include heat as a reactant or product in each equation. Here is what I answered: NaNO3 (s) = Na+ + NO3- + heat NaC2H3O2 + Heat = Na+ + C2H3O2-(ag) Lab data table attached to determine where to place heat. AGO no...
