Solution

Chemical reaction

  • A chemical reaction is a process by which one chemical substance changes into another chemical substance.
  • For example, iron rusts, coal burns, candles burn, papers burn, milk sets into cottage cheese or ghee, food digests, etc.
  • A chemical change occurs during a chemical reaction because a product substance is formed that has entirely different characteristics from the original substance.

Borax is heated strongly

  • Borax is a solid that is amorphous and white in appearance.
  • Sodium tetraborate decahydrate is another name for borax.
  • The chemical formula is Na2B4O7·10H2O.
  • Borax changes through a number of transitions when heated. It initially swells after losing water molecules.
  • It then changes into a clear liquid and then solidifies to form a substance known as "borax bead."

Balanced chemical reaction

  • The reaction is as follows:

Na2B4O7·10H2O(Borax)-10H2ONa2B4O7B2O3(Boricoxide)+2NaBO2(Sodiummetaborate)

  • It is composed of boric oxide (B2O3) and sodium meta borate (NaBO2).
