The last equation you have written out would be the correct single replacement reaction.
The answer should be D. If the red molecules are oxygen and the compound in NO2, we need the answer to have two red atoms. Also, since the question says there are two NO2 molecules, we need to have an answer with two. Therefore, D is the answer.
Answer:
C - composition
Explanation:
Minerals can be classified based on their chemical composition which is expressed in their physical properties. Minerals are described by their physical properties which includes color, crystal form, hardness, density and luster.
The chemical composition is not only used for the classification of minerals, minerals are also classified by determination of internal structures accomplished through the use of X rays.
