Which element does not react with cold or hot water
Answers
Answer:
noble elements
Explanation:
noble elements like gold Au, silver Ag, platinum Pt are less reactive and participate in chemical reactions only under extreme conditions. thus don't react with hot or cold water.
Many other elements are also resistive towards the reaction with hot and cold water like aluminium Al, zinc Zn, and iron Fe. but they react with steam.

Answer:
Iron is a element which is not react with cold or hot water.
Explanation:
As per the data given in the question we have to find element.
Sodium, calcium, and magnesium are metals that are strongly reactive to water and form hydroxides. Iron is a less reactive metal that exhibits no reaction when exposed to both cold and hot water. However, when combined with steam, metal oxides and hydrogen gas are formed.
Reaction of metals with cold or hot water depends on the reactivity of the metals.
Reactive metals like sodium, potassium, calcium, etc. react with cold or hot water. Moderately reactive metals like magnesium react with hot water. Less reactive metals do not react with cold or hot water but react with steam. Least reactive metals like gold, silver, etc. do not react at all.
Less reactive metals like iron react with steam to form an oxide and release hydrogen gas.
Iron is a less reactive metal that exhibits no reaction when exposed to both cold and hot water.
Hence, Iron is a element which is not react with cold or hot water.
