A chart of the reactions of metals

The reactivity series decides which metals react with cold water, steam and dilute acid. You will write the rule, build a table of results for eleven metals, and count the metals that give hydrogen with acid. Then the program colours the table.

The idea. Down to calcium, metals react with cold water. Down to iron, they react with steam. Above hydrogen, they give hydrogen with dilute acids.

Your tasks.

1. In reacts, return True or False for a metal and "water", "steam" or "acid".
2. Fill table with one row per metal: [water, steam, acid] as 1 or 0.
3. Count n_acid, the metals that give hydrogen with dilute acid.
