Answer:
i don't have one :(
Explanation:
just doing for points sorry plz mark me as brainliest
Answer: C, B, A
Explanation:
C is the initial solution, because naoh has not been added yet
B is the midpoint of the titration. naoh has been added to the solution, but it has not fully reacted yet. You can tell that this one is the midpoint because there is still HF- in the diagram, which is not one of the products formed in the reaction.
A is the endpoint because the diagram shows that all products are fully formed. There is an increased amount of Na+ and H2O in the diagram and no HF- left.
PS. I tested this answer on the concentration of acetic acid post-lab (from mcgraw hill) earlier today and it said this was the right answer :) hope this helps
Explanation:
An acid is a substance that ionizes to produce excess hydrogen ion in solutions.
- A concentrated acid contains a high amount of hydrogen ions in solution compared to other ions.
- Such solutions usually ionizes completely.
- A dilute solution contains a high proportion of water and with low amount of hydrogen ions.
- They do not ionize easily and as fast as strong acids.
Answer:
True
Explanation:
A proton has a charge of +1, while an electron has a charge of -1. This is why a neutral atom has the same number of protons as electrons.
Neutrons have no charge, hence their name neutron which is similar to neutral.
