If the carbonate is warm then it could cause a small explosion or shatter the tube it is in.
No reaction occurs
The temperature of the water will rise.
The solution will turn yellow
Formation of a copper sulfate solution in water. This solution has a herbicide and fungicide effect.
Yes. The reaction creates copper sulfate, water, and carbon dioxide gas, which escapes as fizz.
Yes, but copper hydroxide will precipitate.
well here's a hint - copper sulphate is soluble in water, but calcium carbonate isn't.
CuO + H2SO4 -> CuSO4 + H2O copper sulfate and water produced
No, it dosent. If a base can be dissolved in water, its corresponding metal oxide must be able to be dissolved in water. So you see copper hydroxide is solid, which means it can't be dissolved in water. So copper oxide can't react or be dissolved in water to form copper hydroxide.
Copper(II) carbonate is insoluble in water and doesn't react with sodium sulfate. A green product, visible on ald objects made from copper or copper alloys, is a mixture of copper carbonate and copper hydroxide.
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".
Nothing, because calcium carbonate is insoluble in pure water but slightly acidic water as tap water may dissolve it slowly.
