Predict products: Hydrochloric acid + magnesium (remember: produces salt and hydrogen!)
Magnesuim chloride + hydrogen
18 of 21
Magnesium is __ reactive then hydrogen
more
19 of 21
This means mag. can easily d___ (replace) hydrogen in acids
displace
20 of 21
Iron reacts slowler wityh Hydrogen then mag. why?
Iron is closer (although still higher) to hydrogen on reactant series so will take longer to react as it's only slightly more reactive
