What is the proper formula unit for the combination of copperII ions and chloride ions Cl?
The proper formula unit for the combination of copper(II) ions and chloride ions is CuCl2. In this compound, each copper ion carries a 2+ charge (Cu^2+) and each chloride ion carries a 1- charge (Cl^-). The subscript 2 in the formula indicates that two chloride ions are needed to balance the charge of one copper(II) ion.
What is the complete ionic equation for CopperII sulfate Barium Chloride?
The complete ionic equation for the reaction between copper(II) sulfate and barium chloride is: Cu^2+(aq) + SO4^2-(aq) + 2Ba^2+(aq) + 2Cl^-(aq) → BaSO4(s) + CuCl2(aq)
What is the oxidation number of copperII?
The oxidation number of copper (II) is +2. This means that copper has lost two electrons in a chemical reaction and has a charge of +2.
If you wish to obtain 10.0 grams of copper metal from copperII sulfide what mass of copperII sulfide must you use - A.10.0 grams B.24.6 grams C.607 grams or D.15.0 grams?
B. 24.6 grams. To find this, you must first calculate the molar mass of Cu and CuS. This will give an idea of the mole ratio between Cu and CuS. Then, you can use stoichiometry to determine that 24.6 grams of Cu₂S will yield 10.0 grams of Cu.
Does extra addition of ammonia dissolve CopperII sulfide?
No, the addition of extra ammonia will not dissolve Copper II sulfide. Copper II sulfide is insoluble in water and ammonia solution; it does not react with ammonia to form soluble complexes.
Is copperII chloride a metal?
No copper (II) chloride is an ionic compound.
What is the compound for copperII chloride?
Copper(II) chloride is already a compound; its formula is CuCl2
What is the chemical equation for copperII chloride?
The chemical formula (not equation) of copper(II) chloride is CuCl2.
Chemical formula copperII hydroxide?
CuOH2
What is the formula for the compound copperII iodide?
Formula: CuI2
What is the chemical formula for lead copperii sulfate solution?
PbCu2
The compound CuCl2 is named copperII chloride why is a roman numeral is used in one name but not the other?
The Transition metals can have variable charges depending on what they are bonded to. In this example the Copper atom is deficient by two electrons one for each Chlorine atom.
What is the proper formula unit for the combination of copperII ions and chloride ions Cl?
The proper formula unit for the combination of copper(II) ions and chloride ions is CuCl2. In this compound, each copper ion carries a 2+ charge (Cu^2+) and each chloride ion carries a 1- charge (Cl^-). The subscript 2 in the formula indicates that two chloride ions are needed to balance the charge of one copper(II) ion.
Explain why the name for MgCl2 is magnesium chloride but the name for CuCl2 is copperII chloride?
They are identical - bonding two elements to form a binary compound. The only difference is that copper can be found as copperII or copperIV so it's correct to specify which one, that's all. Save with Pb (lead) and other unique metals/nonmetals.
