Water is a substance made up of molecules that are dipoles. The oxygen atom in a water molecule has a slight negative charge, while the hydrogen atoms have a slight positive charge, resulting in an overall dipole moment.
It is an element
Gonna try and describe this the best I can +, -, + with the arrow facing up ^really hope it helps :)
Substances made up of two or more different molecules are called compounds. An Ionic compound is made up of a non metal and a metal while a covalent compound is made up of a non metal and another non metal. There is no such thing as a compound composed of a metal and a metal.
Carbon monoxide is a pure substance, as it is made up of molecules that are all identical (one carbon atom and one oxygen atom). It does not contain different types of molecules mixed together.
Naphthalene is considered a pure substance because it is a chemical compound made up of only naphthalene molecules. It has a definite and consistent chemical composition, with uniform properties throughout its structure.

the building blocks of substances are called what atoms or molecules?

starch molecules
It is a molecule (not plural). 1 carbon, 2 oxygen (=oxide).

A gas is a substance made up of neutral atoms or molecules that changes its shape and volume when placed in a new container. Gases have particles that are widely dispersed and move freely, allowing them to fill the space available to them.
It's not accurate to refer to a volume measurement like liters as "molecules." Liters measure the volume of a substance, while molecules represent the individual particles that make up a substance. The number of molecules in 50 liters of a substance would depend on the type of substance and its density.
If you mean a substance made up of only one atom, that would be a mono-atomic element, and would be a noble gas.If you mean a substance made of only one kind of atoms, that would be an element.
Polymers are substances that have large molecules made up of repeating units called monomers. Examples include plastics, DNA, proteins, and carbohydrates.
A sound wave is simply a vibration in the air molecules, or the molecules of some other substance. This vibration propagates as a wave, the energy gets transferred somewhere else.
