Answer: Option (B) is the correct answer.
Explanation:
It is known that flow of electrons is known as current. Also, we know that electrons carry a negative charge.
Therefore, when parallel wires carrying current in the same direction then due to the same charge there will be repulsion between the electrons.
Thus, we can conclude that Ampere showed that parallel wires carrying current in the same direction would repel each other.
Answer:
656.25 mL
Explanation:
M1 = 0.40 M
M2 = 1.50 M
V2 = 175 mL
Plug those values into the equation:
M1V1 = M2V2
(0.40)V1 = (1.50)(175)
---> V1 = 656.25 mL
The 6 M solution NaOH solution diluted before titrating the vinegar sample because pH at the equivalence point changes very rapidly . It is very useful to have dilution solution , so that number of moles that are transferred per drop of the solution is low . So, pH change smaller amount per drop. Having more dilute solution also allows the titration to use volume that is easier to work with.
If you used the 6 M solution was used then the volume required for titration would go down by a factor of 6/0.3 = 20
This means that if a titration took 20ml of the 0.3 M solution then it would take 1ml of the NaOH solution.
Titration consists of adding a controlled and known amount of standard solution with an unknown until the reaction to be complete.

Primary consumers eat plants, which are producers. Producers are essentially he beginning of the food chain. Secondary consumers eat primary consumers. This means that organisms who are both primary and secondary consumers are omnivores. In this case, Organism A is a carnivore, Organism B is an omnivore, Organism C is an omnivore, and Organism D is an omnivore. The difference between Organisms C and D is that Organisms C eat insects, which are primary consumers, whereas Organism D eats fish, which are secondary consumers.
Answer: C and D
