Hint: Metal is a group of materials with high electrical and thermal conductivity, as well as malleability, ductility, and high light reflectivity. Aluminium, iron, calcium, sodium, potassium, and magnesium are the most common minerals in the Earth's crust.
Complete answer:
When metals react with water, metal oxide and hydrogen gas are produced. Metal hydroxide is formed when soluble metal oxides dissolve in water. Water, on the other hand, has no effect on all metals.
\[
Metal{\text{ }} + {\text{ }}Water{\text{ }} \to {\text{ }}Metal{\text{ }}oxide{\text{ }} + {\text{ }}Hydrogen \\
Metal{\text{ }}oxide{\text{ }} + {\text{ }}Water{\text{ }} \to {\text{ }}Metal{\text{ }}hydroxide\; \\
\]
Metal hydroxide is formed when metal oxide and water are mixed together. The formation of a product is determined by the metals' reactivity, which determines whether they can react with cold water, hot water, steam, or no water at all. Metals with higher reactivity (relatively less reactive than sodium and magnesium) can react with only water to form hydroxide because their hydroxides are stable in solutions (they are highly basic in nature), whereas metals with lower reactivity (relatively less reactive than sodium and magnesium) can only react with steam to create hydroxide, which is not thermally stable and therefore breaks down into iron oxide and water.
Metals like lead, silver, gold, and copper, on the other hand, do not react with metals at all. Since gold and silver are the least reactive metals, they do not react with water. The surface of metallic lead is covered by a thin layer of lead oxide, $PbO$. As a result, it does not react with water in normal circumstances.
The correct option is B.
Additional Information:
The following are some of the most popular uses for sodium carbonate also known as washing soda:
It is a cleaning agent that is used in the home for things like laundry. Many dry soap powders contain sodium carbonate as an ingredient.
It is used to remove both temporary and permanent water hardness.
It is used to make glass, soap, and paper, among other things.
It is used in the production of sodium compounds such as borax.
Note:
It makes no difference which metal or acid is used; if a reaction occurs, we still get hydrogen gas in addition to the salt. However, the speed of the reaction is determined by the metal used and its position in the reactivity chain.
