One gram of Sn was electroplated from a SnCl, solution in 30 minutes. What was the current used?

Andrews [41]

Answer:

0.903 A

Explanation:

We have given mass of Sn = 1 gram

Time t=30 minutes=30×60=1800 sec

According to Faraday law m=zit

Where z is electron chemical equivalent

z is calculated by $z=\frac{atomic\ mass}{nF}$ where n is number of element and F is Faraday constant

So $z=\frac{atomic\ mass}{nF}=\frac{118.71}{2\times 96500}=0.000615$

So $1=0.000615\times i\times 1800$

i =0.903 A

hello your question is incomplete attached below is the complete question

Pyridinium ion is more soluble in 0.1 M HCL (aqueous solution) and this is because the Pyridine ion reacts with NaOH and after the reaction it comes out neutral.

N-acetyltyrosine methyl ester is more soluble in 0.1 M HCL while

B-napthol is more soluble in 0.1 M NaOH because it forms phenoxide ion

Explanation:

Pyridine ion is more soluble in 0.1 M HCL (aqueous solution) and this is because the Pyridine ion reacts with NaOH and after the reaction it comes out neutral.

N-acetyltyrosine methyl ester is more soluble in 0.1 M HCL while

B-napthol is more soluble in 0.1 M NaOH because it forms phenoxide ion

A certain ore is 24.3% nickel by mass. how many kilograms of this ore would you need to dig up to have 55.0 g of nickel?

zysi [14]

Let x be the mass of the ore in grams such that the equation that would allow us to answer this item would be,

55 = (x)(0.243)

The value of x is calculated as,

x = 55/0.243
x = 226.337 grams

Then, solve for amount in kilograms by dividing the calculated value by 1000. This methodology will give us an answer of 0.226337. Hence, the answer is 0.226.
