Answer:
1. Chemical reactions
2.Substances
3. Properties
4. Precipitate
5. Light
6. Temperature
7. Color
8. Gas
Explanation:
During chemical reactions, new substances that possess new properties are formed. During the process of chemical reactions, evidences are found. Some of the evidences are formation of precipitate or light gel, production of gases and changes in colour and temperature.
Chemical reactions start with the substances or compounds which are known as reactants. The reactants react to form new substances known as the products which possess new properties.

Mole =mass ÷ Mr
∴mass = mole×Mr =0.10 × (23+35.5) = 5.85
the answer is D...
The Mr is obtained from the periodic table
<u>Answer</u>:
Organisms living near hydro-thermal vents get their energy from Sulphur.
<u>Explanation</u>:
The hot springs found near the Underwater volcanoes at convergent plate boundaries and spreading ridges are called as Hydro-thermal vents . The organisms that live near these hydro-thermal vents are capable of living in very hot water that has a temperature of 65°C to 100°C that would kill most surface organisms.
Also, organisms present at depth of the hydro-thermal vent are adapted to very high and extreme pressure. The water in this vent are very rich in Hydrogen Sulphide .This hydrogen sulphide has very rich amount of energy. Although the is toxic, the bacteria and other living organism are adjusted themselves to make use of the energy in the Hydrogen sulphide.
