What happens to C u x C l y dot z H2O when it is heated in a crucible at 100 degrees C?
The sample turns tan as water is driven out.
What will you be adding to the C u x C l y solution to collect copper metal?
Aluminum wire
Use the following data to answer the following question:
Mass of empty crucible: 12.237 grams
Mass of crucible and hydrated sample: 13.237 grams
Mass of crucible and dehydrated sample: 13.023 grams
What is the mass of the hydrated sample?
mass of the hydrated sample:
13.237 grams - 12.237 grams = 1.000 g
Use the following data to answer the following question:
Mass of empty crucible: 12.237 grams
Mass of empty crucible and hydrated sample: 13.237 grams
Mass of crucible and dehydrated sample: 13.023 grams
What is the mass of the dehydrated sample?
mass of the dehydrated sample:
13.023 grams - 12.237 grams = 0.786 g
Use the following data to answer the following questions:
Moles of copper: 0.001142
Moles of water: 0.00238
Moles of chlorine: 0.00238
What is the mole ratio of chlorine to copper (chlorine:copper)?
chlorine : copper -> 0.00238 : 0.001142
0.00238 / 0.001142 = 2.084060
2.084060 / 1 = 2.08/1
chlorine : copper -> 2.08 : 1 OR 2 : 1
