ਸੰਜੀਵ ਨੇ ਅਧਿਆਪਕ ਤੋਂ ਪੁੱਛਿਆ ਕਿ ਰਸਾਇਣਿਕ ਸਮੀਕਰਣ ਨੂੰ ਸੰਤੁਲਿਤ ਕਰਨ ਲਈ ਇਹਨਾਂ ਵਿੱਚੋਂ ਕਿਹੜੇ ਨਿਯਮ ਦੀ ਪਾਲਣਾ ਲਈ ਕੀਤੀ ਜਾਂਦੀ ਹੈ ?
A) Law of Conservation of motion ਉ। ਗਤੀ ਦਾ ਸਾਖਿਅਣ ਨਿਯਮ
B) Law of Conservation of momentum ਅ) ਸਵੇਗ ਦਾ ਵਿਖਿਅਣ ਨਿਯਮ
C) Law of Conservation of mass
ਏ) ਪੰਜ ਦਾ ਸੁਰਿੱਖਿਅਦ ਨਿਯਮ
D) None of the above​

Answer 1

Answer:

law of conservation of mass

Explanation:

hope it helps

Answer 2

Answer:

To balance a chemical equation, law of conservation of mass must be obeyed.

Therefore the option (C) is correct.

Explanation:

• According to the law of conservation of momentum, the mass can neither be created nor be destroyed.
• A chemical reaction in a closed vessel, the species can convert from one form to another. But their mass remains constant.
• Therefore the sum of mass of all the reactants is equal to the sum of mass of products.

Therefore, the answer of Sanjeev's question to his teacher is law of conservation of mass.
