An element is a substance that can’t be broken down into simpler substances by chemical means, a compound is when two or more elements are combined chemically to form something new, and a mixture is when two or more substances are combined but not chemically.
Answer:
Can you please provide the elements?
Explanation:Attach a file or tyoe the names into the question
Explanation:
More is the intermolecular forces present between the molecules of a substance more will be the boiling point of the substance.
Since, water is able to form hydrogen bonding and it also have dipole-dipole interaction as these are stronger than the forces present in ammonia. Hence, boiling point of water is greater than the boiling point of .
In , there are only dispersion forces present in it and these forces are weakest intermolecular forces.
As a result, the enthalpies of vaporization of the following substances increase in the order .
This answer to this question is a rule that is applied to any reaction taken at dynamic equilibrium, with respect to 500 K. In other words, you can say that this reaction is of no use to us -
In a chemical equilibrium, it is known that the forward and reverse reactions occur at equal rates. At this point the concentrations of products and reactants remain constant, or in other words do not change
