Answer 2

'A' is Silica (Si) whose oxides dissolve in NaOH and the Oxide of Si is used in manufacturing fire clay bricks.

• Oxide of Silica is used in manufacturing fire clay bricks.
• Fire bricks are used in furnaces and kilns.
• Silica does not react with water.
• The oxide of Silica can be dissolved in NaOH.
• Silicon dioxide reacts with NaOH when it is hot and concentrated.

Hence, the Oxide of Silicon is used in manufacturing fire clay bricks and Si does not react with water but its oxides dissolve in NaOH.
