What is a word equation to show the formation of the black coating on the surface of copper?
The formation of the black coating on the surface of copper can be represented by the word equation: copper + oxygen → copper(II) oxide. This reaction occurs when copper reacts with oxygen in the air, resulting in the formation of a black, tarnished layer of copper(II) oxide on the metal's surface.
Write a word equation to describe the decomposition of copper carbonate on heating?
CuCO3 ==> CO2 + CuO (heat is the catalyst, written above the arrow)
Symbol equation when copper carbonate is heated?
Here are the equations for the thermal decomposition of copper carbonate (notice that a metal oxide is formed, just as it was with calcium carbonate): Copper carbonate → copper oxide + carbon dioxide CuCO3 → CuO + CO2
What is the word equation for adding copper(2) oxide to sulphuric acid?
The chemical reaction is:CuO + H2SO4 = CuSO4 + H2O
What is formed when magnesium reacts with copper oxide?
It decomposes to form copper oxide and carbon dioxide. It is an endothermic reaction, which means it absorbes energy (as all decomposition reactions do). This is the chemical equation of the reaction: CuCO3 ----> CuO + CO2
What is the word equation for corrosion of copper?
The word equation for the corrosion of copper is: Copper + Oxygen + Water → Copper Oxide.
Write a word equation for copper oxide?
The chemical formula for copper oxide is CuO.
What is the word equation for carbon and copper oxide?
Carbon + Copper oxide -> Copper + Carbon dioxide
What is the word equation for copper plus oxygen?
The word equation for copper reacting with oxygen is: copper + oxygen → copper oxide.
What is the word equation for the reaction between copper oxide and sulfuric acid?
Copper oxide reacts with sulfuric acid to form copper sulfate and water. The word equation is: Copper oxide + sulfuric acid → copper sulfate + water.
What is the word equation for copper oxide?
Since there are two valence states for copper, Cu+ and Cu2+, there are two compounds formed from copper and oxygen:Copper (I) Oxide = Cu2O (equation: 4Cu + O2 --> 2Cu2O)Copper (II) Oxide = CuO (equation: 2Cu + O2 --> 2CuO)
Write a word equation for the reaction that takes place in a copper oxide?
Copper oxide (CuO) reacts with hydrogen gas (H2) to form copper (Cu) and water (H2O). The word equation for this reaction is: copper oxide + hydrogen gas → copper + water.
What is the word equation when Malachite is heated?
When malachite is heated, it decomposes into copper(II) oxide and carbon dioxide. The word equation for this reaction is: Copper(II) carbonate (malachite) → Copper(II) oxide + Carbon dioxide.
What is the word equation for when hydrochloric acid reacts with copper oxide?
Balanced equation: CuO + 2HCl --> CuCl2 + H2O Word equation: One mole of copper (II) oxide plus two moles of hydrochloric acid produces (or yields) one mole of copper (II) chloride plus one mole of water.
What is the word equation for 2Cu O2 ---2CuO?
The word equation for the reaction 2Cu + O2 -> 2CuO is: Copper + Oxygen -> Copper(II) oxide.
What is a word equation to show the formation of the black coating on the surface of copper?
The formation of the black coating on the surface of copper can be represented by the word equation: copper + oxygen → copper(II) oxide. This reaction occurs when copper reacts with oxygen in the air, resulting in the formation of a black, tarnished layer of copper(II) oxide on the metal's surface.
What is the word equation of copper oxide reacting with sulfuric acid to make copper sulphate?
Copper oxide+ Sulphuric acid ----> copper sulphate +water
