Answer:
-Grignard reagents are strong bases (third choice)
-Grignard reagents are strong nucleophiles ( second choice)
A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes. The temperature remains constant during these phase transitions.
I would say d but I’m not sure
Answer: the percentage of acetic acid will be low.
Explanation: The major aim during titration of acids and bases is to determine the endpoint , that is exact point where the acid in the beaker changes colour, (in this case, pink )with an additional drop from the burette containing the base, since it is usually difficult to mark the equivalence point that tells us when all the substrate in the beaker has been neutralized completely with the buretted substance.
Overshooting the end point is an error which can occur when the person involved in the the titration accidently goes beyond this endpoint by adding too much of the substance(base) from the burette into the beaker missing the exact endpoint.
This implies that the person has added too much of the burreted liquid, ie the base than required , making the acid in the beaker to continue to react resulting to a lower concentration of the acid (acetic acid) with excess base.(NaOH)
Explanation:
The total mass is:
100 g + 200 g
= 300 g
The mass of salt is:
0.20 (100 g) + 0.10 (200 g)
= 20 g + 20 g
= 40 g
So the concentration is:
40 g / 300 g
≈ 13.33%
Round as needed.
