Calcium has valency 2 and cl is diatomic molecule and 2 elctron is transferred to cl2 from calcium.ionic bond generally ocuurs in between metal and non metal.so due to transfer of electron, there exist ionic bond between cacl2
C describes plastics that can be recycled. Thermoplastic can be remolded and reheated after forming, whereas thermoset strengthens when heated
Answer:
The catalyst speeds up the chemical reaction.
Explanation:
The process in which chemical reaction rate increases by addition of substance is termed as a catalyst. The chemical reaction happens faster when a catalyst is present because it gives an alternative reaction pathway with lower activation energy.
The catalyst usually forms a temporary intermediate that helps in regenerating the original catalyst in the cyclic process. Yeast when added in a mixture work as a catalyst and helps with chemical reaction.
