Which oif the nine substances are made of two elements?
Water (H2O), carbon dioxide (CO2), and salt (NaCl) are examples of substances made of two elements.
How many different substances can be made with four elements?
It depends on the elements! If two of them are carbon and hydrogen, hundreds of compounds can be made from these elements alone. If the four elements are all noble gases, no new substances can be made from them by chemical reaction.
What are compounds and elements called?

Which oif the nine substances are made of two elements?
Water (H2O), carbon dioxide (CO2), and salt (NaCl) are examples of substances made of two elements.
Distinction is made between these two kinds of pure substances?

Are elements and compounds two types of substances?

What is the answer to elements and compounds?
Elements are substances that cannot be broken down into simpler substances by chemical means and are listed on the periodic table. Compounds are substances made up of two or more elements chemically bonded together in fixed proportions.
How are elements and compound different?
Elements are made up of only one thing. While a compound is made of two of more elements. Here is an example. H2O. Water is hydrogen and oxygen.
Why aren't compounds and elements the same?

What is classification of substance?
Substances can be classified as elements, compounds, or mixtures. Elements are made up of only one type of atom, compounds are made up of two or more different elements chemically bonded together, and mixtures are combinations of two or more substances that are not chemically bonded.
What are compounds and elements called?

What are Elements and counpounds?
Elements are substances that cannot be separated into simpler substances. Salt is made up of the elements sodium and chloride. Water is made up of the elements hydrogen and oxygen. A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds.
What are the two kinds of subtances in science?
The two main types of substances in science are elements and compounds. Elements are the simplest form of matter and cannot be broken down further. Compounds are made up of two or more elements chemically bonded together.
