A metal object is to be gold-plated by an electrolytic procedure using aqueous AuCl3 electrolyte. How much gold may be deposited
Rudik [331]

Answer:

This is the answer

Explanation:

charges passed = current x time = 10 x 3 x 60

= 1800 C

mole of charge = 1800 / 96500

= .01865 moles

Au+3 contains 3 positive charges

3 mole of charge will deposit 1 mole of Au .01865 moles will deposit .01865 / 3 mole

= 6.2167 x 10-3 moles.

Convert 98.7 °F to Celsius<br> Formula for Fahrenheit to Celsius
dmitriy555 [2]

Answer:

\boxed {\tt 37.0555556 \textdegree C}

Explanation:

The formula to convert Fahrenheit to Celsius, use the following formula.

C=(\textdegree F -32)*\frac{5}{9}

We want to convert 98.7 degrees Fahrenheit to Celsius, so we must substitute 98.7 in for degrees Fahrenheit.

C=(98.7 -32)*\frac{5}{9}

Solve inside the parentheses. Subtract 32 from 98.7.

C=(66.7)*\frac{5}{9}

Multiply 66.7 by 5/9.

C=37.0555556

98.7 degrees Fahrenheit is equal to 37.0555556 degrees Celsius
