Is ammonia a pure substance?
No, ammonia is a compound composed of nitrogen and hydrogen atoms. It is not a pure substance as it is made up of different elements chemically bonded together.
How would you see if a substance is a mixture or pure?
A substance is considered a pure substance if it consists of only one type of atom or molecule throughout. On the other hand, a mixture is composed of two or more different substances physically combined. One way to determine if a substance is a mixture or pure is by performing a separation technique like distillation or chromatography to see if it can be broken down into its components.
Is o2 a pure substance?
No, oxygen gas (O2) is not considered a pure substance. It is a compound made up of two oxygen atoms bonded together. A pure substance consists of only one type of atom or molecule.
What do mixtures and pure substances have in common?
Mixtures and pure substances are both made up of different types of matter. However, mixtures contain two or more substances physically combined, while pure substances contain only one type of substance with a specific composition.
What makes a pure substance a pure substance?
A pure substance is made up of only one type of atom or molecule, meaning it has a consistent and uniform composition throughout. This distinguishes it from mixtures, which contain varying proportions of different substances. Examples of pure substances include elements like gold and compounds like water.
Is ammonia a pure substance?
No, ammonia is a compound composed of nitrogen and hydrogen atoms. It is not a pure substance as it is made up of different elements chemically bonded together.
Is silicone a pure substance or a mixture?
Silicone is a pure substance made up of silicon, oxygen, carbon, and hydrogen atoms. It is not a mixture because these atoms are combined in a specific and consistent ratio.

Is a uranium a pure substance a mixture. and element or a compound?
Uranium is an element. It is a pure substance because it is made up of only one type of atom - uranium atoms.
Is copper wire a pure substance mechanical mixture or a solution?
Copper wire is a pure substance, as it is made entirely of copper atoms.
Is hydrogen chloride a pure substance or mixture?
Hydrogen chloride is considered a pure substance because it is a chemical compound made up of hydrogen and chlorine atoms in a fixed ratio.
What is the substance made up of atoms?
All substances are made up of atoms. Atoms are the basic building blocks of matter and are composed of protons, neutrons, and electrons. These atoms combine to form molecules, which make up different substances.
What is the general name for a pure substance containing different atoms chemically joined together?
A general name for a pure substance containing different atoms chemically joined together is a compound. Compounds are formed when atoms of different elements bond together through chemical reactions to create a new substance with unique properties.
What is the difference in a pure substance and a mixture?
A pure substance is made out of only one kind of element (for example, gold is a pure substance). A mixture is made out of two or more different substances and is only combined by physical means. A pure substance cannot be broken down into a simpler substance. A mixture can be separated into its component parts.
