When you heat copper carbonate why does it turn lime water milkey?

When copper carbonate is heated, Cu(CO3) forms Copper Oxide CuO and CO2. When Co2 is passed through lime water, it reacts with the calcium in the solution to form the precipitate, calcium carbonate Ca(CO3) which makes the water "milky".

The effect of heat on copper carbonate?
CuCO3(s)-----heat---->CuO(s)+CO2(g) black
How does black copper oxide form?
CuCO3 + Heat --> CuO + O2 Green Copper Carbonate when heated will form Copper Oxide and Oxygen
Which Has An Greater Specific Heat Water or Copper?
Water has.
What are the effects of heat on sodium carbonate?
sodium oxide, carbon dioxide and water 2nd answer: there will be no effect on sodium carbonate if it is heated as sodium carbonate will not be decompose upon heating.
Why does copper carbonate decompose to make copper 2 oxide not copper 1 oxide?
Because it is easier. The molecular formula of copper carbonate is CuCO3. When it decomposes it loses a CO2 molecule. If it became Copper 1 oxide(Cu2O then it would have to combine with another molecule(releasing O). Instead it becames copper2 oxide(CuO) because that is an easier transition.
Why does green copper carbonate go black?
Because it undergoes thermal decomposition. If you give heat to Copper (II) carbonate, it will decompose to form Copper (II) oxide. Instead of saying green copper carbonate, I guess it is safer and better to say copper (II) carbonate.

When you heat 0.80g of copper carbonate and you weigh it after cooling how come the mass didn't change?
Heating copper carbonate (CuCO3) should result in the generation of copper oxide (CuO) and carbon dioxide gas (CO2). Therefore, the weight (mass) of the material remaining should decrease by an amount equal to the mass of CO2 lost. If the mass didn't change, you didn't heat the copper carbonate sufficiently to cause the decomposition.
Why are hot water tanks made out of copper?
keep heat in copper is a good heat conductor.
Which Has An Greater Specific Heat Water or Copper?
Water has.
If the specific heat of aluminum is 0.902 and the specific heat of copper is 0.268 what makes copper a better choice to use for hot water lines in your house?
This means that copper will not absorb the heat from the water as much as the aluminum. Aluminum will "steal" more heat from the water- which you do not want. You need the heat to stay with the water until it serves its purpose.
Thermal decomposition of copper carbonate?
Endothermic because thermal decomposition is the breakdown of a compound using heat. Remember endo means more energy is taken in breaking the bonds of copper carbonate than there is given out when making the bonds of copper oxide and carbon dioxide.
How do you separated the copper sulfate from water?
Heat it
What are the effects of heat on sodium carbonate?
sodium oxide, carbon dioxide and water 2nd answer: there will be no effect on sodium carbonate if it is heated as sodium carbonate will not be decompose upon heating.
What happens when you heat copper?
Copper Oxide (CuO) + Water (H(sub2)O)
A calorimeter contains 0.750 kilogram of liquid water at 17.0 degrees C. A 0.0580 kilogram block of copper at 98.0 degrees C is placed in the water. What is the final temperature of the system?
You need to know the specific heat for copper. Then use q = mc∆T for copper and water. Heat lost by the copper MUST equal heat gained by the water. You can then solve for T2 of the water.
