6: What is a chemical change

A chemical change occurs when one or more substances are transformed into new substances with different chemical compositions.

A chemical change occurs when one or more substances are transformed into new substances with the same chemical compositions.

A chemical change occurs when one or more substances are transformed into new substances with different physical compositions.

A chemical change occurs when one or more substances are transformed into new substances with the same physical compositions.

7: What is state change

A state change, also known as a phase change, refers to the transition of elements from one state to another due to changes in temperature or pressure.

A state change, also known as a phase change, refers to the transition of matter from one state to another due to changes in temperature or pressure.

A state change, also known as a phase change, refers to the transition of matter from one state to another due to changes in density or viscosity

8: Why is a color change physical

A color change is often considered a physical property because it doesn't involve the alteration of the substance's chemical composition.

A color change is often considered a physical property because it involves the alteration of the substance's chemical composition.

A color change is often considered a physical chemical because it doesn't involve the alteration of the substance's chemical composition.

9: Why is matter that has a definite composition a homogeneous mixture

Matter with a definite composition is classified as a homogeneous mixture when its components are clumped together

Matter with a definite composition is classified as a heterogeneous mixture when its components are uniformly distributed throughout

Matter with a definite composition is classified as a homogeneous mixture when its components are uniformly distributed throughout

10: Why is a transparent liquid with a definite melting point either an element or a compound

A transparent liquid with a definite melting point is likely an element or a compound because their specific chemical structures allow for this property.
