Question

write two example of compound:-​

Answer 1

Answer:

Water - Formula: H2O = Hydrogen2 + Oxygen

Two atoms of the element Hydrogen combine with one atom of Oxygen through a covalent bond to form water. Hydrogen has a slightly positive charge and oxygen has a negative charge, and therefore it forms a polar molecule. Water can be split back into hydrogen and oxygen through electrolysis.

2. Hydrogen Peroxide - Formula: H2O2 = Hydrogen2 + Oxygen2

Hydrogen peroxide is formed when two atoms of hydrogen form a bond with two atoms of oxygen that have bonded to each other. Although it has only one more oxygen atom than is present in a molecule of water (H2O), its properties are very different.

3. Salt - Formula: NaCl = Sodium + Chlorine

In salt, one atom of sodium bonds to one atom of chlorine to produce the resulting ionic compound sodium chloride. Salt is quite easily produced for commercial uses by simply evaporating seawater, although it can be mined from the ground as well. Sodium chloride can be separated into its different atoms through electrolysis.

4. Baking Soda - Formula: NaHCO3 = Sodium + Hydrogen + Carbon + Oxygen3

Sodium bicarbonate (baking soda) can be produced from the reaction of carbon dioxide with an aqueous solution of sodium hydroxide, which creates sodium carbonate; it is then combined with carbon dioxide molecules to produce sodium bicarbonate. It is found naturally in hot springs and other places on earth, but is commercially produced for industrial uses.

5. Octane - Formula: C8H18 = Carbon8 + Hydrogen18

Octane is a hydrocarbon whose actual formula is CH3(CH2)6CH3. It's a low-molecular weight compound, which means its highly volatile and flammable, making it ideally suited for the production of gasoline.

Answer 2

Answer:

Define: Compounds are pure substances formed y the chemical combination of two or more elements in a definite proportion by mass.

Examples:

1. Water is a compound. A water is made up of two atoms of hydrogen and one atom of oxygen. ($H_{2}O$)

2. Sugar is a compound. A sugar molecule is made up of twelve atoms of carbon, twenty two  of hydrogen and eleven atoms of oxygen.($C_{12} H_{22} O_{11}$)
