Declan Fleming is a chemistry teacher and author of our Exhibition Chemistry column. Similarly, they might see demonstrations of the more reactive metals with water or even explore these themselves practically. How long will it take to cook a 12 pound turkey? Active metals react with water/steam to produce metal hydroxides and hydrogen. Mg +2 H2O---> Mg(OH)2 + H2. This approach gives some pupils the impression that the two types of reactions are disparate. The end of the tubing should protrude at least 2 cm from the rubber to enable the evolved hydrogen from the demonstration to be lit.
