Explanation

The core principle behind a hydrogen bomb is the fusion of light atomic nuclei.

Specifically isotopes of hydrogen (deuterium and tritium), under extremely high temperatures and pressures. 

Explanation

The carbon dioxide (CO₂) molecule has a linear structure, with a bond angle of 180°.

Due to the two double bonds between carbon and oxygen atoms.

Explanation

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is produced when coal is burned without sufficient oxygen.

CO is highly toxic.

It can be deadly in high concentrations, as it displaces oxygen in the bloodstream.

Explanation

Chemical energy is stored in a dry cell.

A dry cell is a device that converts chemical energy into electrical energy.

Chemical energy is the energy stored in the bonds of atoms and molecules. 

Explanation

Explanation

Explanation

Thermal energy is produced during fission reactions in nuclear reactors, which is used to generate electricity.

Explanation

Silicon is a chemical element with the symbol Si and atomic number 14.

Silicon dioxide (SiO₂) is the primary component in glass, making it transparent and durable.

It is obtained from sand (quartz).

It is essential in glass manufacturing

Explanation

Limestone consists of calcium carbonate,

which has the chemical formula CaCO3.

Calcium carbonate is a chemical compound.

It is a common substance found in rocks as the minerals calcite.

Explanation

Bleaching powder is synthesized by reacting chlorine gas with calcium hydroxide (Ca(OH)₂).

The chemical formula of bleaching powder is Ca(OCl)Cl.
