The easiest way to solve these problems is to use what is called a unit multiplier. First begin with the number of grams of copper that you have, then use the unit multiplier that expresses the number of grams per mole of copper (this is the number that corresponds to the Atomic Mass on the Periodic Table times grams, divided by moles). Then use the number of copper atoms that it takes to create copper oxide; this will depend on the oxidation state of the copper. Finally it reverse the process by adding up the atomic masses of copper oxide, and that will be the number of grams per mole of copper oxide, returning you from Moles back to Grams.

Which salt changes from green to black on heating?
Copper carbonate
What method is used to separate copper from copper sulphate solution?
By heating copper sulfate is decomposed in copper(II) oxide and sulfur trioxide; by reduction of the copper oxide with hydrogen copper is obtained.
What compound will be formed between copper ion and carbonate ion?
Copper and carbonate ions form copper carbonate. In practice, copper carbonate usually contains hydroxide ions as well.
How do you remove colour from copper sulphate using anhydrous?
The hydrated copper sulfate (blue color) become white after heating and releasing of water; the white anhydrous copper sulfate is obtained.
What is the precipitate of copper sulphate and sodium carbonate?
The copper(III) carbonate is a precipitate.
Which salt changes from green to black on heating?
Copper carbonate
Describe the appearance and odor of the liquid obtained by heating copper 11 sulfate pentahydrate?
Describe the appearance and odor of the liquid obtained by heating copper II sulfate pentahydrate.
Does carbonate produce copper oxide when heated?
Carbonate by itself is an ion that does not contain copper and therefore could not produce copper if heated. However, because carbonate is a negatively charged ion, no substantial number of carbonate ions can exist stably except in association with an equal number of positively charged cations to neutralize the electrical charge of the carbonate ions. If these cations are cations of copper, then copper oxide can be produced by heating the copper carbonate salt.
Heating CuCO3 produces carbon dioxide and what?
Heating CuCO3 (copper (II) carbonate) produces carbon dioxide (CO2) and copper oxide (CuO).
Compound for copper carbon and oxygen?
Copper Carbonate.
What is the name of this ternary salt cu2co3?
copper(II) carbonate or cupric carbonate
Why does CuCO3 turns black when heated?
on heating copper carbonate decomposes to cupric oxide which is black in colour.
What method is used to separate copper from copper sulphate solution?
By heating copper sulfate is decomposed in copper(II) oxide and sulfur trioxide; by reduction of the copper oxide with hydrogen copper is obtained.
By heating green copper carbonate so that it changes to black copper oxide will this be a chamical or physical change?
Chemical, the resultant molecules have different structures and properties.
What compound will be formed between copper ion and carbonate ion?
Copper and carbonate ions form copper carbonate. In practice, copper carbonate usually contains hydroxide ions as well.
Why Hydrated copper sulfate crystals cannot be obtained from a solution by direct heating?
Heating the saturated solution of Copper sulfate will not form the hydrated copper sulfate crystals because only after cooling down the saturated solution of copper sulfate then only the crystals of the hydrated copper sulfate can be formed
What is copper carbonate plus potassium?
Potassium Carbonate and Copper metal
