Answer:
False
Explanation:
It is not correct to assert that a chemical change has occurred if the number of atoms is greater after the reaction than it was before the reaction.
For every chemical reaction, the law of conservation of mass must be strictly adhered.
The law states that "during a chemical reaction, matter is neither created nor destroyed, atoms are simply rearranged".
By the virtue of this law, the number of atoms at the beginning and the end of the reaction must remain the same for this law to be applicable.
Answer:
The higher the temperature, the more soluble most ionic solids are in water
As you cool a saturated solution from high temperature to low temperature, solids start to crystallize out of solution if you achieve a supersaturated solution.
If you raise the temperature of a saturated solution, you can (usually) add more solute and make the solution even more concentrated.
Explanation:
For many ionic solids, solubility in water increases with increase in the temperature of the solution.
This implies that increasing the temperature allow more solute to dissolve in the solvent, supersaturation may be achieved by so doing. As the solution is cooled, the solid crystalizes out of solution hence the answers above.
