Hello everyone so here we have a question that we have to balance the following chemical equation by filling in the blanks with the correct whole number stoichiometry coefficients.
00:10
So what is given in the question is we have to balance the chemical equation.
00:20
Chemical equation by filling the blanks with correct stoichiometry coefficient.
00:43
So our question is 3 nh2 gas plus o2 gas forms co2 gas plus n2 gas plus n2 gas plus h2 in gas state.
01:17
Let us see the explanation first and then we will find the answer for this.
01:23
Let us write the chemical equation once again.
01:35
Ch3nh2 plus o2 n2 plus h2.
01:49
We can see that ch3 nh2 here one carbon is there and here also one carbon is there.
02:02
H3 is there in ch3 and h2 5h is there.
02:06
And on the other side only 2h is there so let us write here 4 so with this we can say that 20h on this side and here we have to write to make it 20 to make this 2 o on the other side 20 we have to write 10 in this 6 in the right hand side ultimately this will become 902 and this will become 4 co2 and this will become 2 end.
02:47
Now let us count the number of carbon.
02:50
They are on left hand side number of carbons were 4, number of hydrogens were 20, number of nitrogen's were 4 and number of oxygens were 18.
03:11
Let us see on the right hand side if it will become equal then we have balanced the equation number of carbons were 4 number of hydrogens were 20 number of nitrogens were 4 and the number of oxygens were 18 so lhs was equals to rhs 4n 8n 8 oxygen so option c option c which is 4 plus 9 forms 4 plus 2 10 is the answer now let us move on to the next question that is blank e3 88 plus blank o2 blank co2 plus blank h2o now let us see the explanation for this let us write down the chemical equation once more time e3 h8 plus o2 comes co2 plus co2 plus h2 let us see on the left left hand side there are three carbons and on the right hand side there are one only one carbon to balance this we can write here as one and here we can write as one and here we can right as 3...
