Which of the following is the correct equation for the reaction below?
One molecule of methane gas reacts with two molecules of oxygen gas to
form one molecule of carbon dioxide gas and two molecules of water vapor.
O
A. CH (g) + O2 (g) - CO (g) + H20 (g)
O B. CH (9) + 20 (g) → CO(g) + 2H0 (9)
O C. CH4 (g) + 2O2 (g) – có (g) + 2H20 (g)
OD. CHA (9) + 202 (9) ► 02 (9) + H20 (9)

CH₄   +     2O₂    →      CO₂   +     2H₂O

Explanation:

This kind of reaction in which a hydrocarbon combines with oxygen gas is a combustion reaction. They are mostly used to produce heat energy that can be transformed into other forms of energy.

 Every chemical reaction is made up of reactants and products. The combining species on the left hand side are the reactant and the products are the result of the combination.

  Note: in writing chemical equations, the state of matter must always be included.

   Reactants :    Methane gas     CH₄

                          Oxygen gas        O₂

   Product:        Carbon dioxide   CO₂

                         Water vapor        H₂O

       CH₄   +     2O₂    →      CO₂   +     2H₂O

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
