In the above double displacement reaction, exchange of ions take place and aqueous solution of sodium chloride and white coloured precipitate of barium sulphate are formed . If the reactants are taken in solid state i.e. other than aqueous state then the reaction won't take place cause a precipitate is formed only when we mix two aqueous solutions ( also exchange of ions won't take place).

Respiration occurs in the cells of all living organisms. 3. Photosynthesis occurs in the chloroplast. 3. Respiration mainly takes place inside the mitochondria. 4. It takes up the carbon dioxide from the atmosphere and produces oxygen. 4. Oxygen is used in this process to produce carbon dioxide.

Oil and fat containing food items are flushed with nitrogen Why?

Posted by Vaishnavi Vaishu 1 month ago

CBSE > Class 10 > Science

2 answers

Srushti Lande 3 weeks, 5 days ago

Nitrogen is an inert gas and does not easily react with these substances. On the other hand, oxygen reacts with food substances and make them rancid. Thus, bags used in packing food items are flushed with nitrogen gas to remove oxygen inside the pack. When oxygen is not present inside the pack, rancidity of oil and fat containing food items is avoided.

2Thank You

Arti Kumari 1 month ago

When fats and oils are oxidised they become rancid and their smell and taste change usually substances which prevent oxidation(antioxidants such as nitrogen, vaccum packing) are added to foods containing fats and oil keeping food in air tight containers helps to slow down oxidation so that oil and fat containing food items are flushed with nitrogen
