Answer: The percent is 25.263%
Explanation:
False the ability to conduct heat is a physical property
Answer:
0.210 M
Explanation:
<em>A 75.0 mL aliquot of a 1.70 M solution is diluted to a total volume of 278 mL.</em>
In order to find out the resulting concentration (C₂) we will use the dilution rule.
C₁ × V₁ = C₂ × V₂
1.70 M × 75.0 mL = C₂ × 278 mL
C₂ = 0.459 M
<em>A 139 mL portion of that solution is diluted by adding 165 mL of water. What is the final concentration? Assume the volumes are additive.</em>
Since the volumes are additive, the final volume V₂ is 139 mL + 165 mL = 304 mL. Next, we can use the dilution rule.
C₁ × V₁ = C₂ × V₂
0.459 M × 139 mL = C₂ × 304 mL
C₂ = 0.210 M
Answer:
The quantities of electrical charge that are they can produce are the same
Explanation:
The quantity of electrical charge produced by an electrochemical cell is given by
Number of moles of electrons × Faraday's constant.
since the number of moles of electrons involved in the two electrochemical reactions are the same (2 moles of electrons each) then the charge that they can produce will also be the same.
Hence the answer.
