Question

numerical response
1.
listed in order from the least reactive metal to the most reactive metal, the four
metals are
,
,
, and
least reactive
most reactive
(record all four digits of your answer in the numerical - response section on the answer sheet.)

Explanation:

Step1: Analyze reaction with water

The more reactive a metal is, the more vigorously it reacts with water. Metal 2 has a reaction with water, while metals 1, 3, and 4 have no reaction. So metal 2 is more reactive than 1, 3, 4 in terms of water - reaction.

Step2: Analyze reaction with dilute acid

Metal 2 has an explosive reaction with dilute acid (most vigorous among the given reactions with dilute acid). Metal 1 has a slow reaction, metal 3 has a reaction, and metal 4 has no reaction.

Step3: Analyze reaction with oxygen

Metal 2 has a reaction with oxygen. Metal 1 has no reaction, metal 3 has a reaction, and metal 4 has no reaction.

Combining the three types of reactions (water, dilute acid, oxygen), we can rank the reactivity. Metal 4 has the most "no - reaction" (least reactive). Metal 1 has more "no - reaction" compared to metal 3. Metal 2 has the most vigorous reactions.
