In this question we have to find the balanced equation out of the given equation.
00:08
So first we will consider the first equation that what we have 2al plus 3o2 gives 2al2o3 ok.
00:19
So let us check whether the equation is balanced or not.
00:21
So at the reactant side we have many aluminium, 2 aluminium and on the product side also we have 2 aluminium.
00:28
So aluminium is balanced.
00:31
Now we will check the oxygen, we have how many oxygen? we have 2, 3, 6 oxygen on the end side but on the product side we have only 3 oxygen.
00:41
So oxygen is not balanced.
00:44
So we will write b for the balanced and nb for the non -balanced.
00:47
So as because oxygen is not balanced so the reaction is not balanced.
00:51
Now we move to the second reaction we have n2 plus 2h2 gives what? gives 2nh3 ok.
01:01
Now let us consider this equation so n nitrogen 2 nitrogen here 2 nitrogen here.
01:08
So this nitrogen is what? balanced.
01:10
Now we go for the hydrogen so here we have 4 hydrogen but on this side we have 6 hydrogen.
01:15
So hydrogen is not balanced.
01:18
So whole of the reaction is also not balanced.
01:21
Now we move to the third reaction so what we have in third reaction we have ch4 plus 3o2 gives to what? gives to co2 plus 2h2o.
01:36
Now here we have carbon so we have 1 carbon here on the reactant side and 1 carbon on the product side.
01:45
So carbon is balanced...
