Answer:
The answer to your question is below
Explanation:
Data
Test tube 1 Test tube 2
Magnesium + Sulfuric acid Magnesium + Acetic acid
Mg + H₂SO₄ Mg + CH₃COOH
a) Test tube 1 will have a more vigorous reaction than test tube 2.
b) Sulfuric acid is a strong acid and Acetic acid is a weak acid.
c)
i.- Sulfuric acid because is a strong acid
ii.- Acetic acid because is a weak acid.
Answer: Mass of silver deposited at the cathode is 37.1g
Explanation: According to Faraday Law of Electrolysis, the mass of substance deposited at the electrode (cathode or anode) is directly proportional to quantity of electricity passed through the electrolyte
Faraday has found that to liberate one gm eq. of substance from an electrolyte, 96500C of electricity is required.
+e− ==> Ag(s)
Given that
Current (I) = 8.5A
Time (t) = 65 *60 = 3900s
Quantity of electricity passed = 8.5*3900 =33150C
Molar mass of Ag= 108g
96500C will liberate 108g
33150C will liberate Xg
Xg= (108*33150)/96500
=37.1g
Therefore the mass of Ag deposited at the cathode is 37.1g.

Answer:
The flocculation basin often has a number of compartments with decreasing mixing speeds as the water advances through the basin. ... This compartmentalized chamber allows increasingly larger floes to form without being broken apart by the mixing blades.
