a)Determine if reaction occurs or show balanced chemical reaction b)Do a net ionic reaction |
a)Determine if reaction occurs (by making balanced complete chemical reaction). Include this even if reaction does not occur. b)Even if the reaction does not occur find the Net Ionic reaction |
3) If you react 72.3g ammonium nitrate with potassium carbonate (enough to react), how many grams of each product do you make? |
3) If you react 72.3g ammonium nitrate with potassium carbonate (enough to react), how many grams of each product do you make (so you will do the calculation twice once for each product)? |
|
4. If you react 21.6g of Zinc wire (Zn as an element) in an Aluminum iodide solution (enough to react), how many grams of each of the products do you make? |
