Substance that cannot be changed into a simpler substance under normal laboratory conditions are elements. A physical blend of two or more substances that are not chemically combined is a mixture.
Polypropylene is considered inert because it does not react with other substances and is stable under normal conditions. This makes it a common choice for materials that come into contact with food or chemicals, as it does not leach harmful substances.
Substances that conduct an electric current under certain conditions are most likely to be metals or solutions containing ions. Metals have free electrons that can move through the material, allowing for the flow of electric current. Ionic solutions contain ions that can move and carry charge, enabling them to conduct electricity.
Alcohol is stable under normal conditions and dilutes in water. It is a colorless, volatile liquid that can dissolve a wide range of substances.
Inactive substances typically exhibit minimal or no reactivity under standard conditions, meaning they do not readily engage in chemical reactions or interactions. This lack of reactivity is often due to stable electron configurations or the absence of functional groups that could participate in chemical processes. Such substances can serve as inert materials or fillers in various applications, ensuring they do not interfere with the desired chemical reactions or processes.
Yes.
metalloids
Urea, creatinine, uric acid, and water are the main substances found in urine under healthy conditions. Other components may include electrolytes, hormones, and other waste products.

Repeatability...multiple experiments conducted under identical conditions serve to prove the results of the initial experiement.

A baseball is not a substance and does not have a boiling point. Boiling points are defined for substances that can change from a liquid to a gas under specific conditions, such as water.
No, ammonia is not combustible, meaning it cannot catch fire. However, when ammonia is mixed with certain substances, it can become potentially explosive under certain conditions.
