These data help justify an atomic view. Methane is a pure substance because it always has the same. In comparison, elements retain some (or many) of their property when they are mixed to. These combinations take place because almost all. For example, hydrogen and oxygen atoms combine in a ratio of 2:1 to form the. Atoms cannot be created or destroyed. Web the elements carbon and hydrogen combine to form many different compounds. Atoms consist mainly of electrically charged particles. Web atoms of the same element are similar in shape and mass, but differ from the atoms of other elements. The fourth part of the theory states that a chemical reaction is a rearrangement of atoms.
Web combination reactions can also be called synthesis reactions. Web the third part says compounds are combinations of two or more different types of atoms.

Web combination reactions can also be called synthesis reactions. Atoms cannot be created or destroyed. Web law of multiple proportions, statement that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed. One of the simplest is called methane, in which there are always four times as many hydrogen atoms as carbon atoms. For example, hydrogen and oxygen atoms combine in a ratio of 2:1 to form the. Web when elements combine to form compounds: Web when two or more elements combine to form a compound, their masses in that compound are in a fixed and definite ratio.
