What reaction would the chemical equation ch4 + 2o2 →2h2o + co2 represent? combustion of methane replacement of methane formation of methane decomposition of methane

The reaction represent the COMBUSTION OF METHANE.

A combustion reaction is said to occur when an hydrocarbon react with oxygen to produce carbon dioxide and water. The chemical equation given above shows the interaction between methane [which is an hydrocarbon] and oxygen; the products are carbon dioxide and water, this shows that the reaction is a combustion reaction. During the course of the reaction, the chemical bonds in oxygen and methane get broken down and they re-arrange to yield the products; energy is given off in the course of the reaction.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
