Question

Balance this chemical equation: CH4 + 02 -→ CO2 + H2O​

Answer 1

`\huge \boxed{\mathrm{CH_4+ 2O_2 \Rightarrow CO_2 +2 H_2O}}`

`\rule[225]{225}{2}`

Step-by-step explanation:

`\sf CH_4+ O_2 \Rightarrow CO_2 + H_2O`

Balancing the Hydrogen atoms on the right side,

`\sf CH_4+ O_2 \Rightarrow CO_2 +2 H_2O`

Balancing the Oxygen atoms on the left side,

`\sf CH_4+ 2O_2 \Rightarrow CO_2 +2 H_2O`

`\rule[225]{225}{2}`

Answer 2

CH4 + 2O2 -----> CO2 + 2H2O

Step-by-step explanation:

What are the rules in balancing chemical equations

1 . Write the correct chemical formulas for all the reactants and products

2. Count the total number of atoms or ions of each element in the reactants and also of the product

3. Balance the elements one at a time using coefficient

4. Check each atoms or ions to ensure correctly balanced

5. Make sure that all the coefficient are in the lowest possible whole number ratio

CH4 + O2 ---------> CO2 + H2O

reactant. Product

Write out each number of atoms of each element for both the reactant and the product

Reactant. Product

1 C 1C

4H 2H

2O 3O

balance each element at a time

CH4 + O2 --------> CO2 + H2O

let's balance H2O by adding coefficient of 2

CH4 + O2 -----> CO2 +2 H2O

since :H - 4 at the reactant and also at the product

: O - 4 at the product but 2 at the reactant

Let's add the coefficient of 2 to O to balance the equation

CH4 + 2O2 -----> CO2 + 2H2O

C. C

4H. 4H

4O. 2O + 2O = 4O

so our chemical equation is balanced

CH4 + 2O2 -----> CO2 + 2H2O
