گھر میں پانی سے ایل پی جی گیس بنانے کا طریقہ

 Preparing gas from CaCO3 (calcium carbonate) and water at home involves a simple chemical reaction, producing carbon dioxide (CO2). This process is often used for educational demonstrations or as a source of CO2 for various applications.

To prepare gas from CaCO3 and water, you will need the following materials:

1. Calcium carbonate (CaCO3) powder, which is commonly available as limestone or marble chips.

2. Water (H2O).

3. A glass or plastic container.

4. A balloon 

Process

1. Crush the CaCO3 into a fine powder, increasing its surface area to promote the reaction.

2. Place the powdered CaCO3 in the container.

3. Slowly add water to the container, creating a mixture with the CaCO3. The chemical reaction between CaCO3 and water produces CO2 gas, which will escape from the container.

4. To capture the CO2 gas, stretch a balloon  over the container's opening. As the gas is generated, it will inflate the balloon.

5. Allow the reaction to continue until the balloon is sufficiently inflated.

This simple experiment demonstrates the production of CO2 gas from CaCO3 and water, making it an engaging and educational activity for understanding basic chemical reactions. For kitchen use  watch video     Watch
