We are going to balance the chemical equation.
00:03
Balance means the number of atoms, number of atoms in reactant side, reactants and products, products should be equal, should be equal.
00:26
And here how can we balance this? we will compare the coefficients by comparing the coefficients.
00:39
The first given equation is bas plus n2 gas form ba3n2 solid.
00:53
So here we will see number of barium in case of the product is 3 but the reactant is 1.
01:01
So after balancing we will get 3 barium solid plus n2 gas will form ba3n2 solid.
01:18
The next one is given ag solid plus h2s aqueous is forming ag2s solid plus h2 gas.
01:34
Here we will see the coefficient in the product we have ag2, 2 number of silver where in reactant we have only 1 ag.
01:45
That is why after balancing we will multiply 2 ag solid plus h2s aqueous will be forming ag2s solid plus h2 gas.
02:00
Coming to the third equation, number c equation which is c2h6 gas plus o2 gas forming co2 gas plus h2o gas.
02:21
Here we will see carbon over here is 2 but in the product we have 1 whereas hydrogen over here is 6 and hydrogen in the product is 2...
