There are two atoms of Bromine (Br) and one atom of Copper (Cu) in this compound. Thus, there are two elements, but three atoms.
Zn + CuBr2 = Cu + ZnBr2
103
There are two elements, carbon and hydrogen.
The current periodic table contains 118 elements, as of April 2010, but many more may still be discovered.
117 elements
Zn + CuBr2 = Cu + ZnBr2
The percent composition for CuBr2 is: Cu= 28.45% Br= 71.55%
AgI and CuBr2 are both soluble in water. AgI is slightly soluble and CuBr2 is highly soluble in water, forming a greenish solution due to the presence of copper ions.
The balanced equation for the reaction between zinc (Zn) and copper (II) bromide (CuBr2) is: Zn + CuBr2 → ZnBr2 + Cu

The classical method for preparing CuBr2 involves reacting copper oxide or carbonate with hydrobromic acid. This reaction forms copper bromide and water as products. The balanced chemical equation for this reaction is CuO + 2HBr -> CuBr2 + H2O.
Formula: CuBr2
The formula for copper (II) bromide is CuBr2. It consists of one copper (Cu) atom bonded to two bromine (Br) atoms.
Cu+2 Br-1
Cubr2 is the chemical formula for copper(II) bromide, which is a compound containing copper and bromine ions. It is a yellowish crystalline solid that is used in organic synthesis and as a catalyst in certain reactions.
copper 2 bromine is not a chemical name. copper and bromine are both elements. the term "copper 2" suggests divalent copper, ie copper in the Cu++ state. Bromine is almost always a monovalent anion, ie Br-. Copper bromide is then one copper ion and two bromine ions together forming CuBr2.
No, the chemical formula CuBr2 indicates one atom of copper bonding with two atoms of bromine. This means that the molar mass of CuBr2 is not equal to the sum of the molar masses of copper and bromine individually.
