Explanation: In solids, particles are very closely packed in an orderly arrangement in a lattice and only vibrate in fixed positions. The forces of attraction between them are very strong. This allows them to overcome the forces of attraction that hold the other phases closer together
All are the same elements but they differ in their atomic mass therefore this process will called Isotopes
Answer:
They are the same.
Reaction B has a higher activation energy
Reaction A will most likely proceed faster
The criteria that will allow Amol separate group 1 substances into two groups are mixtures and pure substances (option B).
<h3>What are mixtures and pure substances?</h3>
Mixtures are substances that are made up of two or more substances that can be easily separated.
Pure substances, on the other hand, are elements and compounds that cannot be separated by chemical means.
In group 1 of the above table, the substances can be classified as follows:
- Soil - mixture
- Tomato ketchup - mixture
- Smoke - compound
- Milk - mixture
- Hair shampoo - mixture
Therefore, the criteria that will allow Amol separate group 1 substances into two groups are mixtures and pure substances.
