When a stronger affinity for this element is needed, the chelating agent EGTA is used instead of EDTA. (10[1])Silicates of this element are sintered together to form the clinker used to make Portland cement. Palladium deposited on a compound of this metal (-5[1])makes up a Lindlar catalyst. (-5[1])This element (-5[1])produces an orange-red color in (-5[1])the flame test. (-5[1])Ions of magnesium and (-5[1])this metal are prevalent in hard water. (10[1])Quicklime (10[1])is the oxide of this element, while slaked lime is its hydroxide. (10[1])This element’s sulfate makes up the mineral gypsum and its carbonate makes up limestone. For 10 points, name this alkaline (10[1])earth metal found in teeth and bones. ■END■ (10[4])
