Question

the following equation, what will be the value of a+b+c?
CH4+aO2-bCo2+cH2O
(a) 8
(b) 7
(d) 5
(C) 6​

Answer 1

Answer:

The required answer is option d)5 .

Explanation:

Equation given -

CH4 + aO2 →bCO2 + cO2

Balancing the equation -

CH4+2O2 → 1CO2 + 2H2O

Checking out the balancing :

Number of Carbon Atoms:

Left Hand Side = 1

Right Hand Side = 1

LHS = RHS

Number of Hydrogen Atoms:

Left Hand Side = 4

Right Hand Side = 4

LHS = RHS

Number of Oxygen Atoms:

Left Hand Side = 4

Right Hand Side = 4

LHS = RHS

Hence a + b + c = 2 + 1 + 2 = 5

Answer 2

Answer:

Explanation:

Given :-

CH4 + aO2 →bCO2 + cO2

To Find :-

a + b + c = ??

Solution :-

CH4 + aO2 →bCO2 + cO2

Balancing the equation, we get

CH4+2O2 → 1CO2 + 2H2O

Showing out the balancing of equation :-

Number of Carbon Atoms :-

Left Hand Side = 1

Right Hand Side = 1

LHS = RHS

Number of Hydrogen Atom :-

Left Hand Side = 4

Right Hand Side = 4

LHS = RHS

Number of Oxygen Atoms :-

Left Hand Side = 4

Right Hand Side = 4

LHS = RHS

Adding all the values

= a + b +  c

= 2 + 1 + 2

= 5

Hence, the value of  a+ b +  c is 5.
