Reaction between copper and oxygen?
AnswerCu + O2 --> CuOIn other words, the elements that reacted were:Oxygen and Copper;forming Copper Oxide
When 2.50 g of copper reacts with oxygen the copper oxide product has a mass of 2.81 What is the simplest formula of the copper oxide?
(2.5 grams =) 0.0393 moles of copper reacts with (0.31* grams =) 0.0194 moles of oxygen to produce something that has a ratio of 2.0 moles copper to 1 mole oxygen. Copper has a +1 and a +2 oxidation state and Oxygen has (usually) a -2 oxidation state so we know it isn't CuO because that's a 1:1 ratio. Cu2O has a 2:1 ratio...what could it be? *notice that the subtraction: 2.81g - 2.50 g = 0.31 g, reduced my significant digits to two.
Which atoms are found in copper sulphate?
Copper Sulphate is composed of copper, sulfur, and oxygen. The chemical formula is CuSO4.
What is 1 atom of copper 1 atom of sulfur and 4 atoms of oxygen?
A formula unit for copper (II) sulfate, with formula CuSO4.
What is the balanced formula for copper plus oxygen-----copper oxide?
There are two different copper oxide formula's:2Cu + O2 -> 2CuO (black Copper(II) oxide)or4Cu + O2 -> 2Cu2O (red Copper(I) oxide)
Reaction between copper and oxygen?
AnswerCu + O2 --> CuOIn other words, the elements that reacted were:Oxygen and Copper;forming Copper Oxide
What gas in the air does copper react with and what product is formed?
Oxygen. The product is copper oxide.
What is the product of the reaction between copper and oxygen is?
2Cu + O2 ==> 2CuO product is copper(II) oxide4Cu + O2 ==> 2Cu2O product is copper(I) oxide
What is the chemical formula for copper sulfide?
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper(II) sulfate. Remember that Copper sulfate contains Copper, Sulfate and Oxygen because anything ending with 'ate' therefore contains oxygen
How many atoms in copper carbonate?
Copper carbonate contain copper, carbon and oxygen.

What elements are contained in copper carbonate?
Copper (Cu) Oxygen (O) Carbon (C) The chemical formula for it is CuCO3
Copper 2 sulfate formula?
The chemical formula for copper sulphate is CuSO4. It contains:One copper atomOne sulphur atomFour oxygen atomsIn addition, the natural form of copper sulphate differs with its amount of water molecules. The most commonly encountered form is blue. Its chemical formula is CuSO4•5H2O. It contains: Copper sulphate (see above)Five water molecules, which contain: Two hydrogen atomsOne oxygen atom
What elements make up copper sulfate?
The elements in copper sulphate are copper, sulphur and oxygen. Copper sulphate is a compound, made up of three elements. The symbol for this compound is CuS04.
