166.4 g Ag grams of silver can be produced from 49.1 g of copper.
<h3>What is a mole?</h3>A mole is a very important unit of measurement that chemists use. A mole of something means you have 602,214,076,000,000,000,000,000 of that thing, like how having a dozen eggs means you have twelve eggs.

63.55 g Cu —> 2 x 107.688 g Ag
63.55 g Cu gives 215.376 g of Ag
So, 49.1 g Cu —>
= 166.4 g Ag
Hence, 166.4 g Ag grams of silver can be produced from 49.1 g of copper.

Answer:
8740 joules are required to convert 20 grams of ice to liquid water.
Explanation:
The amount of heat required (), measured in joules, to convert ice at -50.0 ºC to liquid water at 0.0 ºC is the sum of sensible heat associated with ice and latent heat of fussion. That is:
(1)
Where:
- Mass, measured in grams.
- Specific heat of ice, measured in joules per gram-degree Celsius.
,
- Temperature, measured in degrees Celsius.
- Latent heat of fussion, measured in joules per gram.
If we know that ,
,
,
and
, then the amount of heat is:
8740 joules are required to convert 20 grams of ice to liquid water.
