So, we have given here two chemical equations and we have to translate that in the form of chemical formulas, writing proper chemical formulas and to balance the chemical reaction.
00:11
Okay.
00:11
So, now, first of all, we have given that we have sodium chloride in solid phase.
00:22
Okay.
00:22
Solid sodium chloride.
00:23
So, that is nacl in solid phase.
00:26
It reacts with aqua sulfuric acid.
00:29
So this means h2so4 and that is aqueous this means aq dot and now this gives so we have hydrogen chloride gas so that is hcl and that is in gaseous form and then we have given sodium sulfate that is na2so4 and that is in also in aqueous form okay aqueous sodium sulfate.
00:56
Now we need to balance this equation so now if i multiply this by 2 so we have 2 sodium atoms on the left side and 2 sodium atoms on the right side.
01:10
We have 2 chlorine atoms on the left side now and if i multiply this by 2 so we will have 2 chlorine atoms on the right side also.
01:19
We have 2 hydrogen atoms on left side, 2 hydrogen atoms on the right side and we have 1 chlorine sulfur atom on left side, one sulfur atom on right side, four oxygen atom on left side and four oxygen atoms on right side.
01:34
So, in this way the chemical equation is balanced because we have equal number of atoms on both side of equation on the reactant and product side...
