Which term describes a mixture that is uniform throughout but not necessarily a single substance?

• A. Heterogeneous Mixture
• B. Homogeneous Mixture
• C. Pure Substance
• D. Element

Answer: (B)

Uniform composition throughout means you can’t see or separate different parts in the sample, even though it’s made by mixing more than one substance. That’s what a homogeneous mixture is. In a homogeneous mixture, the components blend so evenly that the material looks the same from any small portion you sample. Examples include salt dissolved in water or the air around us. This is different from a heterogeneous mixture, where distinct parts are visible or separable, like a salad with vegetables. It’s also different from a pure substance, which is made of only one kind of material, and from an element, which is a pure substance made of only one type of atom. So, the term that fits is a homogeneous mixture.
