Explanation

Water gas is a mixture of Carbon Monoxide (CO) and Hydrogen (H2).

Water Gas is formed when steam is passed over red-hot coke.

Formula: H₂O

Boiling point: 100°C

Explanation

 Coal gas composition:

Typically contains around 50% hydrogen, 35% methane, and 10% carbon monoxide. 

Production method:

Coal is heated in the absence of air to produce these gases.

In lemonade, lemon juice is the solute, and water is the solvent.

Explanation

Mixing vinegar (acetic acid) with baking soda (sodium bicarbonate) produces carbon dioxide gas, water, and sodium acetate.

This is a chemical reaction with visible fizzing, showing a new substance is formed.

Explanation

Explanation

Combustion is a chemical process in which a fuel reacts with oxygen to produce carbon dioxide, water, and energy (usually in the form of heat or light).

It is an exothermic reaction.

It is commonly seen in burning fuels like wood, gas, or coal.
