What else can I help you with?
The air soil and most foods and beverages are examples of . compounds mixtures pure substances elements?
The air, soil, and most foods and beverages are examples of mixtures. Mixtures consist of two or more different substances that are physically combined but not chemically bonded. They can vary in composition and can include elements and compounds within them. In contrast, pure substances consist of only one type of particle.
Do all bacterial colonies consist of pure cultures?
YES.!!

Can air be pure?
A pure air can be prepared only in laboratory, by mixing the components. Note that air is not a compound but a mixture of gases. In the nature pure air don't exist - the air is polluted.
What does kerosene consist of?

What is a pure element saltwateraluminum foilor rose quartz?
A pure element is an also known as a chemical element. Pure elements consist of only one type of atom. Aluminum is the only pure element in the group.
Is a balloon a mixture or pure substance?
A balloon is typically considered a mixture because it is made up of various materials, including the rubber or latex of the balloon itself and the air or gas inside it. The rubber or latex is a polymer, which is a type of pure substance, but the contents, like air, consist of different gases mixed together. Therefore, the overall composition of a balloon is classified as a mixture.
What do gamma rays consist of only electrons pure energy only protons beta particles?
Gamma rays consist of pure energy in the form of electromagnetic radiation. They do not consist of electrons or protons. Beta particles are high-energy electrons or positrons emitted during certain types of radioactive decay, but they are not present in gamma rays.
What substance are not an alloy?
Substances like pure gold (Au), pure copper (Cu), and pure iron (Fe) are examples of materials that are not alloys because they consist of a single type of atom in their structure.
