I think It might be 329 cm3. I'm not too sure if this answer matches any of your multiple choice questions, and I'm not too sure if this is correct either.
Sorry if I get it wrong. ~(*~*)~
According to Faraday's Law,
W = I t e / F
Where,
W = Amount deposited = 3.66 g
I = Current = 3 A
t = Time = 60 min = 3600 s
e = Chemical equivalence
F = Faraday's Constant = 96500
Solving for e,
e = F W / I t
Putting Values,
e = (96500×3.66) ÷ (3 × 3600)
e = 32.7
As we know,
e = M / 2
solving for M,
M = e × 2
Putting value of e,
M = 32.7 × 2
M = 65.4
M = Zinc
Answer:
An acid
Explanation:
» The reaction of any hydrogen ion or hydroxonium ion with a base results into an acidic solution.
For hydrogen ions:
For hydroxonium ions:
Based on the descriptions, the structural formula is drawn as shown in the attached picture. The ring which is composed of 6 carbon atoms is a cyclic hexane called cyclohexane. The 3-Carbon straight chain attached to the cyclohexane is propyne. The compound has an IUPAC name of propyne cyclohexane.
Answer:
First, the direct method requires recording the total mass of solution, and then evaporating off the solvent. The solid left behind is the solute, which is then weighed and used to calculate mass percent. Density can also be used to determine the mass percent of an unknown concentration.
in my opinion:)
