Below are some examples of Chemical Reactions/Equations.


2H2 + O2 = 2H2O

CU+ H2SO4=CUSO4 + H2

2MG + O2 =2MGO

2NA + CL2 =2NACL

and so on .



I mean is RHS=LHS always true for all Chemical Equations or only for specific chemical equations or not true at all?



2H2O=2H2 + O2

CUSO4+H2=CU+H2SO4

2MG=MG + O2

2NACL=2NA + CL2

and so on ...


If True, False or Some True or False reasons for the same?

It should be Na, Mg, Cu, not NA, MG, CU

The question is poorly worded and poorly stated, I guess what you are asking is whether for a balanced reaction equation total number of atoms of each element on LHS and RHS is identical. Yes, that's the definition of "balanced". That's just a mass conservation, atoms don't appear or disappear at random. Same about charge, if there are ions involved total charge on LHS and RHS must be identical too. When they are not, the reaction is not balanced.

Thank you.

My query was different.

From the given equations/reactions,

2H2O=2H2 + O2
CuSO4+H2=Cu+H2SO4
2MgO=2Mg + O2
2NaCL=2Na + CL2

Can we derive/get Hydrogen gas and Oxygen gas from Water?

Can we derive/get Copper and Sulphuric Acid from Copper Sulphate and Hydrogen gas?

Can we derive/get Magnesium and Oxygen gas from Magnesium Oxide?

Can we derive/get Sodium and Chlorine gas from Sodium chloride?

The Above is possible using any Chemical processes?.

Is this possible in all Chemical Reactions or Few Chemical Reactions or not a single chemical reaction?
Will RHS=LHS work actually in Chemistry laboratories?

If Not, Why?

Macroscopic mass is always conserved in chemical reactions. This is one of the fundamental laws of chemistry. However, just because you can write it down, does not mean it will actually happen in the laboratory - but any reaction that happens will always conserve mass.
