Which of the following metals will not react with oxygen,even when heated very strongly in air?a)Znb)Alc)Agd)FeCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Silver  do not react with oxygen even at high temperatures as they are less reactive and are placed below the reactivity series. Hence they are called noble metals. But silver fades after some months or years due to its tendency to react with sulphur in air forming their sulphides

Answer

Gold ag

Answer

Silver will not react with oxygen even at high temperature
because silver is very less reactive metal as it is kept in the bottom of reactivity series. It is also a noble gas. Silver and gold only react with royal water .

Answer

Answer:

In this question, we are asked to identify the metal that will not react with oxygen, even when heated strongly in air. Let's analyze each option to determine the correct answer.

a) Zinc (Zn):
Zinc is an active metal and readily reacts with oxygen in the air to form zinc oxide (ZnO). The reaction can be represented as follows:
2Zn + O2 → 2ZnO
Therefore, zinc is not the correct answer.

b) Aluminum (Al):
Aluminum is also an active metal and reacts with oxygen in the air to form aluminum oxide (Al2O3). The reaction can be represented as follows:
4Al + 3O2 → 2Al2O3
Therefore, aluminum is not the correct answer.

c) Silver (Ag):
Silver is a noble metal and does not react with oxygen, even when heated strongly in air. This is because silver is highly unreactive and is not easily oxidized. Therefore, silver is the correct answer.

d) Iron (Fe):
Iron is an active metal and readily reacts with oxygen in the air to form iron(III) oxide (Fe2O3), also known as rust. The reaction can be represented as follows:
4Fe + 3O2 → 2Fe2O3
Therefore, iron is not the correct answer.

To summarize, the metal that will not react with oxygen, even when heated strongly in air is silver (Ag).
