Answer 2

Calcium is more reactive than Hydrogen in the given options (Option c).

• The reactivity of a chemical compound is the tendency to participate in a chemical reaction in time.
• We can compare two compounds' reactivity with the help of a reactivity series.
• In the reactivity series, if a compound "x" is in a higher position than another compound "y", then the compound "x" will be more reactive than "y".
• The reactivity series: Potassium, Sodium, Calcium, Magnesium, Aluminum, Carbon, Zinc, Iron, Lead, Hydrogen, Copper, Mercury, Silver, Gold, ......., etc.
• We can observe that from the given options only Calcium is in a higher position than Hydrogen. So Calcium is more reactive than Hydrogen.
