svet-max [94.6K]

We have to convert 0.18 km into feet

First, we need to know the conversions:

1 inch = 2.54 cm (exact)

1 pound = 454 g

1 Liter = 1.0b quarts

1 feet = 12 inches

1 galion = 4 quarts

1 pound = 16 ounces

0.18 km x (1 feet/12 inches) x (1 inch/2.54cm) x (1000 m/1 km) x (100 cm/1 m) = 590 ft

Answer: 590 ft (2 significant figures)

Purification of chromium can be achieved by electrorefining chromium from an impure chromium anode onto a pure chromium cathode
mylen [45]

Answer:

696 h

Explanation:

Let's consider the reduction of Cr³⁺.

Cr³⁺(aq) + 3e⁻ → Cr(s)

We can establish the following relations.

  • The molar mass of Cr is 52.0 g/mol.
  • 1 mol of Cr is deposited when 3 moles of e⁻ circulate.
  • 1 mole of e⁻ has a charge of 96468 c (Faraday's constant).
  • 1 A = 1 c/s
  • 1 h = 3600 s

<em>How many hours will it take to plate 13.5 kg of chromium onto the cathode if the current passed through the cell is held constant at 30.0 A?</em>

13.5 \times 10^{3} gCr.\frac{1molCr}{52.0gCr} .\frac{3mol/e^{-} }{1molCr} .\frac{96468c}{1mol/e^{-}} .\frac{1s}{30.0c} .\frac{1h}{3600s} =696 h
