How can you get copper sulphate from an impure sample?
1. Dissolve the copper carbonate/sulfate salts in water and filter it: the Copper Carbonate is insoluble so it will remain as the residue on the filter paper, and the copper sulfate is soluble so it will pass through the paper as the filtrate. 2. Heat the filtrate in an evaporating basin till the point of crystallization (crystals will form on a rod dipped into the mixture, at the point of crystallization). 3. Leave the filtrate to cool and crystals of pure Copper sulfate will form. Collect the crystals with a spatula and leave them on a sheet of filter paper to dry.
How to prepare dry black copper II oxide from copper carbonate hydroxide?
You place the copper carbonate hydroxide sample in a stainless steel tray and then the tray in an electrically heated furnace, able to reach temperatures above 500 degrees centigrade (measuring thermocable). Then the furnace door is closed and the furnace is switched on. When a temperature of 500 oC in the furnace has been reached, the calcination needs to be carried out over a duration of four hours. The product is pure copper oxide (more accurately: cupric oxide)
If a mineral sample bubbles when acid is dropped on it which of the following properties does it have?
It is probable a carbonate.
How would a dry sample of sodium carbonate be obtained from a mixture of sodium carbonate and calcium carbonate?
Calcium carbonate is not soluble in water, sodium carbonate is soluble in water. Dissolve the mixture and filter: the Na2CO3 pass the filter as a solution and CaCO3 remain on the filter. Gently warm the solution to obtain crystallized sodium carbonate.
What is the smallest particle of matter which retains the identity of the element it comes from i?
An atom. In a sample of copper, for instance, the smallest unit of copper that is still considered copper is a single atom of copper.
A scientist suspect that a mineral sample is a carbonate. which useful for identifying the sample as a carbonate?
A sample of carbonate is acid. Acid is what identifies carbonate in science studies.
Malachite is naturally occurring from copper carbonate. outline how a sample of copper metal could be obtained from large lumps of malachite in the laboratory?
Malachite is a hydrated copper carbonate - Cu2CO3(OH)2; this compound is thermally decomposed in water, carbon dioxide and cupric oxide.Cupric oxixe may be reduced with hydrogen to copper:CuO + H2 = Cu + H2O

How do you calculate the amount of CuS and Cu2S in an ore sample given a known sample amount and amount of impurity?
Copper metal can be prepared by roasting copper ore, which can contain cuprite (Cu2S) and Copper (II) sulfide. Cu2S + O2 -> 2Cu + So2 CuS + O2 -> Cu + SO2 Suppose an ore sample contains 11.0% impurity in addition to a mixture of CuS and Cu2S. Heating 100.0 g of the mixture produces 75.4 g of copper metal with a purity of 89.5%. What is the weight percent of CuS in the ore? The weight percent of Cu2S? Clicked enter too fast, sorry.
What is the volume of 0.1 grams of Copper Carbonate gas?
As the volume of a given gas sample is dependent on its temperature and pressure; to find a volume of any gas which does exist, the temperature and the pressure of the system/vessel should be given directly or could be calculated.
