1.	Compose an activity to arrange Ca, Mg and Fe metals in the decreasing order of reactivity with water. Write suitable balanced chemical equations and draw diagrams.
Answer» Solution :Take some metals like Ca, Mg and Fe etc. PLACE separately small pieces of these metals in beakers with small amount of water in them. If the metals react with the cold water, then the reaction is vigorous. If metals does not react with cold water, then treat it with HOT water. Record the observations and arrange the metals in DECREASING order of reactivity. After this ACTIVITY it can be CONCLUDED that Ca is more reactivity than Mg, which is more creative than Fe.
