Both sides of the equation would be equal.

Answer:
The answer for the frist one is C is a chemical property and D is a physical property. The sconed one this implies both the atoms have the same nucleus but different charges so it can be concluded that they are both the atoms of the same element but one of them is electrically neutral and the other has stable electronic configuration.

Answer:
A pure substance consists only of one element or one compound and a mixture consists of two or more different substances, not chemically joined together.
So, a mixture is like mixing - let's say - sugar and rice together (dry BTW), but you can clearly see both substance are not chemically mixed together, if that makes sense. Thus, you can easily separate them out.
Answer:
1.4 mols
4th answer
Explanation:
22. 5 g of O2 in moles = (22.5/32) mols = 0.703 mol
The stoichiometry between O2 and H2O =1: 2
Therefore H2O produced = 2 * 0.703 mols=1.406 mols
Answer: Option (A) is the correct answer.
Explanation:
It is known that particles of a gas are held by weak Vander waal forces, therefore, there is no force of attraction between gas molecules.
As a result, these particles are in random motion.
Thus, we can conclude that out of the given options, the constant motion of the particles in a gas allows a gas to fill a container.
