Question

Given a chemical reaction, methane (CH4) burns in oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). Which of these represent an unbalanced equation with the correct chemical formulas?. A.. CH4 + O2 CO2 + H2O. . B.CH4+ CO2 O2 + H2O. .C. CO2+ H2O CH4+ O2. .D. CH4 O2 + CO2+ H2O

Answer 1

Answer : The correct option is A.

Explanation :

As per the question, in a reaction, two reactants (methane and oxygen) should be present on the left side of the right-arrow and two products (carbon dioxide and water) which are formed in the reaction should be present on right side of the right-arrow.

Therefore, the unbalanced chemical reaction will be,

$CH_4+O_2\rightarrow CO_2+H_2O$

Answer 2

I think the correct answer among the choices listed above is option A. Given a chemical reaction, methane (CH4) burns in oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). The chemical reaction is best represented as:

CH4 + O2 ----> CO2 + H2O
