What is substance made of two or more elements that have been chemically combined called?
A substance made of two or more elements that have been chemically combined is called a compound. In a compound, the elements are chemically bonded together in fixed ratios to form a new substance with unique properties different from the individual elements.
Why is hydrogen bromide a compound?
Hydrogen bromide (HBr) is a compound because it consists of two elements (hydrogen and bromine) that has been chemically combined to form a new substance. It is a colourless gas with an acrid odor at room temperature.
What is the definiton of elements?
