Listing 10 of 275 questions
Write an equation representing the action of heat on calcium nitrate, Ca(NO3)2. Describe and explain the trend in the thermal stabilities of the nitrates of the Group II elements. Sodium carbonate is stable to heat, but heating lithium carbonate readily produces CO2. Suggest an equation for the action of heat on lithium carbonate. Suggest a reason for the difference in reactivity of these two carbonates. Predict what you would see if a sample of lithium nitrate was heated. Explain your answer.
