Question

Question 8Which of the following is an INCORRECT statement?-A redox reaction involves the transfer of electrons between atoms.-A single reactant is the identifying characteristic of a decomposition reaction.-Two ionic reactants is the identifying characteristic of a single replacement reaction.-The combustion of CH4 will produce CO2 as one of the products.

Answer 1

A single replacement reaction, is a type of reaction in which we have the following set up:

A + BC -> AC + B

As we can see, an element will react and switch places in a molecule, forming a new molecule and a lone element as products, and according to this set up, we don't have two ionic reactants as characteristic for a single replacement reaction, therefore letter C is the incorrect option.
