☆☆☆☆☆the metal on which electroplating is to be done is taken as cathode ( negative electrode) . the metal of which electroplating is to be done is taken as anode ( positive electrode) and the salt solution of the metal of which electroplating is to be done is taken as electrolyte .
example-
if we want to electroplate iron with copper then iron is taken as cathode and copper is taken as anode and electrolyte is copper sulphate.Electroplating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes. This is done through the use of copper in a copper sulfate bath.
Which of the following (what)?
The charge on the polytomic ion cyanide is -1.
H2+Br2-->2HBr
unit conversions give an equal amount but with other units
The stick model method.
The empirical formula for a molecule containing 46.8 percent si and 53.2 percent o is in the middle of the two. These added together and divided by two will net the average result.

Decomposition reaction
Answer this question… Which of the following is the best definition of a physical change?
For Apex: 2H+ + SO42- + Ca2+ +2I- -> CaSO4 + 2H+ + 2I-
In this case the yield is 77,27 %.
heat
In this reaction a change of bonds of the reactants occur: the general form is:
AB + CD = AD + BC
CaCO3 -> CaO + CO2
The products of the hydrocarbon combustion are water and carbon dioxide.
