The C-F electrons will be more attracted to the fluorine atom
Answer:
The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. This implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in the same ratio by mass.
Answer: Physical change: It is reversible process and we can get back to orginal material. Best example is the interconversion of ice into water which inturn into vapour.
Chemical changes are irreversible and we can't get back the original material. Example combustion of coal, rusting of iron
Explanation:
1. Electrolysis of molten MgCl2 is chemical change since we can't get back MgCl2 after Electrolysis and new materials are formed.
2. It is an example rusting of iron comes under chemical changes.
