Question

how to balance chemical equation easier?​

Answer 1

Answer: At first do not go for balancing oxygen and hydrogen . First balance others and at last you will find it easier to balance oxygen and H2

Explanation:

Answer 2

Explanation:

its easy

suppose

C4H10 + O2 > CO2 + H2O

let the coefficients be a,b,c,d respectively for the compounds C4H10,O2,CO2,H2O.

multiply the no.of atoms in the formula with the coefficients and equate them

then solve for each element like this

C> 4a=c (bcoz 4 atoms on LHS in one formula and only 1 on RHS)

H>10a=2d

O>2b=2c+d

now assume a=1 and substitute the value of a in the above equations

c=4 d=5 b=13/2

C4H10 + 6.5O2 > 4CO2 +5H2O

multiply both sides by 2

2C4H10 + 13O2 > 8CO2 +10 H2O

• Imp: This constitutes a set of only three equations for the four unknowns. The fourth condition comes from recognizing that chemical equations specify relative amounts of reactants and products.

• Thus, one of the coefficients is arbitrary, and all the others can be expressed relative to it.

• Thus, we may take one of the coefficients to be 1, arbitrarily, which then leaves only three unknowns and three conditions to determine them.

• The choice of which coefficient to set to 1 is completely arbitrary and may be taken to be the one that is most convenient for solving the problem.
