Way Of Separating Mixtures Quiz

The correct answer is tap water and milk. Homogeneous mixtures are uniform throughout, meaning that the composition is the same in all parts of the mixture. Tap water and milk both meet this criteria as they have a consistent composition and do not separate into different layers or phases. Chocolate chip ice cream, smoke, and vegetable soup, on the other hand, are heterogeneous mixtures as they contain visible different components or phases.

The flammability of a substance is a chemical property because it describes how easily a substance can catch fire or burn. This property is specific to the chemical composition of the substance and is not related to any physical changes or properties.

The correct answer is chocolate chip ice cream, smoke, and vegetable soup. Heterozygous refers to a mixture that contains different components or ingredients. Chocolate chip ice cream is a mixture of ice cream and chocolate chips, smoke is a mixture of gases and particulate matter, and vegetable soup is a mixture of various vegetables and other ingredients. Tap water and milk are not considered heterozygous as they are homogeneous mixtures, consisting of only one component (water and milk, respectively).

The corrosion of a bicycle frame and the formation of water when hydrogen burns are both examples of chemical changes. Corrosion occurs when the metal of the bicycle frame reacts with oxygen in the air, resulting in the formation of rust. The formation of water when hydrogen burns is a chemical reaction between hydrogen gas and oxygen gas, resulting in the formation of water vapor. Both of these processes involve the rearrangement of atoms and the formation of new substances, which is characteristic of a chemical change.

The physical changes are those that do not alter the chemical composition of a substance. Sharpening a pencil, inflating a tire, drawing copper into wire, and boiling water are all examples of physical changes. In these processes, the substances involved undergo a change in form, state, or size, but their chemical composition remains the same.

The size of an object is a physical property because it can be measured and observed without changing the substance itself. Freezing points are also a physical property because they represent the temperature at which a substance changes from a liquid to a solid, without altering its chemical composition. The fragrance of a flower is also a physical property as it can be sensed and observed without any chemical changes occurring.
