Calcium combines with cold water, releasing hydrogen. When lead is heated in air, it changes slowly into an oxide, but it shows almost no reaction with steam. Silver shows no reaction with either air or water. Zinc, when heated with steam, produces hydrogen. Which substances are in order of reactivity, beginning with the least reactive?
- Acalcium → lead → zinc → silver
- Bcalcium → zinc → lead → silver
- Csilver → lead → zinc → calcium
- Dsilver → zinc → lead → calcium
