Question

Quizplus · Accepted Answer

Molecules are two or more atoms chemically joined together. Option A is incorrect as molecules are not a mixture of pure substances, but a pure substance themselves. Option B is not entirely correct as molecules can have different ratios of elements, leading to different compounds. Option D is incorrect as molecules are not heterogeneous mixtures, that is, they are not visibly different from one another. Option E is not entirely correct either, as while molecules can be a type of homogeneous mixture, the definition does not encompass all molecules.
