Final answer:
The statement is true; the ingredients of a mixture can be varied or changed, and a mixture consists of two or more substances mixed together with variable ratios. Mixtures can be either heterogeneous with non-uniform composition or homogeneous with a uniform composition.
Step-by-step explanation:
The statement that the components or ingredients of a mixture can be varied or changed is true. A mixture consists of two or more pure substances mixed together in which the ratio of the constituents is variable. Therefore, you can change the amount of each substance in a mixture without changing its identity as a mixture.There are two types of mixtures: heterogeneous mixtures and homogeneous mixtures. A homogeneous mixture has a uniform composition throughout, like salt dissolved in water. In contrast, a heterogeneous mixture has a composition that varies from one part of the mixture to another, such as a mixture of oil and water or iron filings with flour where the components are not uniformly mixed.
For example, if you have a mixture of sand and water, the proportion of sand to water can be changed by adding more sand or more water, and it will still be a mixture. This also relates to foods, where different ingredients can be added to improve taste, texture, or appearance. A mixture like table salt mixed with ground pepper is another example where different proportions can still retain the identity of the mixture, as each component maintains its own properties and they can be physically separated.
