Answer:

Al (s) | Al³⁺ (aq) || Ni²⁺ (aq) | Ni (s)

Explanation:

It seems that you meant "A voltic cell".

Here, Al (s) represents the solid anode while Al³⁺ is in aqueous phase, these two forms are separated by a solid line. || is the salt bridge while Ni²⁺ is in aqueous phase and is reduced on the nickel cathode that is Ni (s).

4) Find the mass of 1.46 mol of Al2(SO4)3.

ddd [48]

Answer:

1.46mol of Al2(SO4)3 weights 499.5 grams

Explanation:

First we will find the gram formula mass of Al2(SO4)3.

Al * 2 = 26.98 g/mol * 2 = 53.96 g

SO4 * 3 = 96.06 g/mol * 3 = 288.18

53.96 + 288.18 = 342.14 g

That is the mass of 1 mol of AL2(SO4)3.

Now we will multiply 342.14g by 1.46.

342.14 * 1.46 = 499.5244 g

Or ... 499.5 g

PLEASE HELP!

Basile [38]

Answer:

49.54 g

Explanation:

Let's take the masses of both calcium sulfate and sulfur dioxide formed.

Sulfur dioxide = 32 + 2(16) = 64 g

Calcium sulfate = 40 + 32 + 4(16) = 136 g

So, under ideal conditions, to produce 136 g of Calcium sulfate, we require 64 g of Sulfur dioxide.

But, it mentions the process is only 95% efficient.

Hence, taking the ratio :

$\frac{64}{136} = \frac{0.95x}{100}$

$0.95x = \frac{64 \times 100}{136}$

$0.95x = \frac{6400}{136}$

$x = \frac{800}{17} \times \frac{20}{19}$

$x = \frac{16000}{323}$

x = 49.54 g (approximately)
