Part 1: Name the type of chemical reaction that occurs when aluminum (Al) reacts with copper nitrate (Cu(NO3)2). Part 2: Explain why aluminum does not react with potassium nitrate (KNO3) although it reacts with copper nitrate.

How many grams of magnesium metal will react completely with 8.3 liters of 5.5 m hcl? show all of the work needed to solve this problem. mg (s) + 2hcl (aq) → mgcl2 (aq) + h2 (g)
