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.
Gallium + Bromine ----> Gallium(III) Bromide2 Ga + 3 Br2 ----> 2 GaBr3
Br2 + (2e)- --> 2 Br- 2I- --> I2 + (2e)-
Cu (OH)2 = CuO2 + H2O
If the copper nitrate formed is copper (I) nitrate, the equation balances with one atom of each metal and one formula weight of each nitrate. If the copper nitrate formed is copper (II) nitrate, the balanced equation is: 2 AgNO3 + Cu -> 2 Ag + Cu(NO3)2.
Cu2+ + 4NH3 ----> [Cu(NH3)4]2-
This equation is 2 Na + Br2 -> 2 NaBr.
potassium cyanide
The balanced equation is Cu(OH)2 (s) (heat) = CuO + H2O.
Gallium + Bromine ----> Gallium(III) Bromide2 Ga + 3 Br2 ----> 2 GaBr3
Br2 + (2e)- --> 2 Br- 2I- --> I2 + (2e)-
CuSO4 is copper (II) sulfate. The balanced equation for CuSO4 with water is CuSO4 + H2O reacts to become Cu+2 + HSO4-2 + OH-.
This equation is 2 HCl + CuO -> CuCl2 + H2O.
If it exists, its formula would be Cu(HCO3)2.
Cu (OH)2 = CuO2 + H2O
The chemical equation is:Cu(OH)2 + 2 HCl = CuCl2 + 2 H2O
The chemical equation is:2 CuNO3 + Zn = Zn(NO3)2 + 2 Cu
Cu(NO3)2 an NaCl don't react, so there is not a balanced equation.
