This question is confusing to me.
Answer:
part a=A. A physical change, then a chemical change
part b:evidence
without physical change any sorts of chemical change do not take place.
for example: when sugar is heated on spoon the physical change takes place in sugar .sugar starts to form liquid from solid.
Answer:
Intermolecular forces: forces attracting one molecule to its neighbors.
Explanation:
Hello,
Bonds are formed when two molecules are interacting (crashing or attracting to each other) and they are allowed to get joined via their valence electrons since we're talking about bonds. Those forces are called intermolecular forces as long as the molecules have charges that could attract or repeal another molecule (neighbors), of course, as we're considering bonds, we talk about attractive forces, making the bonding to be effective.
Best regards.
Answer:
The amount of ionization in solution.
Explanation:
Strong acids ionize fully in solution to release a large number of hydrogen ions responsible for the acidic properties. On the contrary weak acids ionize partially in solution.
In strong acids less energy is required to break the hydrogen- anion bonds.
