Grade 8 8.5(E)

investigate how evidence of chemical reactions indicate that new substances...

Chemical reactions the process in which atoms are rearranged and chemical bonds are broken and formed to produce a chemical change of a substance
Property characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed
Substances a pure form of matter
Mixture contains a combination of different atoms or molecules and is therefore said to be 'impure'
React to undergo or cause to undergo a chemical reaction
Solid One of the three basic forms of matter, composed of molecules that have little or no ability to exchange places. Unlike gases and liquids, a solid has a fixed shape, and unlike gases, a solid also has a fixed volume.
Liquid One of the three basic forms of matter, composed of molecules that can move short distances. Unlike a solid, a liquid has no fixed shape, but instead has a characteristic readiness to flow and therefore takes on the shape of any container.
Dissolve to go or cause to go into solution
