Compounds are made of more than one type of element bound together in fixed ratios. True or false?

True

Explanation:

There are two major pure substances in Chemistry namely: elements and compounds. Elements are substances made up of only one type of atom which cannot be broken down. For example, H2 symbolizing hydrogen gas is an element.

On the other hand, atoms of different elements can combine together and be held by chemical bonds to form substances called COMPOUNDS. Hence, a compound is pure substance made of more than one type of element bound together in fixed ratios. For example, Al2O3 is a compound comprising of elements Al (aluminum) and O (oxygen) in a fixed ratio of 2:3.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
