Answer:
im sorry im bored can we talk
Explanation:
lol
Solutions of acids and bases are good conductors of electricity because they are capable carrying current. Solutions of such substances have ions in the solution which can carry current through out the solution. Hope this answers the question.
Answer:
The concentration of the most dilute solution is 0.016M.
Explanation:
First, a solution is prepared and then it undergoes two subsequent dilutions. Let us calculate initial concentration:
<u>First dilution</u>
We can use the dilution rule:
C₁ x V₁ = C₂ x V₂
where
Ci are the concentrations
Vi are the volumes
1 and 2 refer to initial and final state, respectively.
In the first dilution,
C₁ = 0.178 M
V₁ = 15 mL
C₂ = unknown
V₂ = 50 mL
Then,
<u>Second dilution</u>
C₁ = 0.053 M
V₁ = 15 mL
C₂ = unknown
V₂ = 50 mL
Then,
Work done = Force * distance = 200 *30 = 6000 Joules
Power = rate of doing work = 6000/10 = 600 watts
The best answer to the question that is being presented above would be letter b. A compound can only be separated into two or more pure substances by a chemical change. Mixtures can be separated without chemical change.
