9 Compound HCl (hydrochloric acid) H2O C6H12O6 (sugar) Two or more elements chemically combined. (forms a new substance)Can only be separated by a chemical reaction. (chemical bonds get broken)Examples:C6H12O6 (sugar)HCl (hydrochloric acid)H2O
10 Mixture Can be made of elements and/or other non-pure substances. Physically combinedCan only be physically separatedExamples: dissolved in water, melted together, mixed together in containerNo new substance is formed
11 Solution Type of mixture All substances evenly distributed Examples: sugar water, salt water, bronze (copper and zinc are melted together)
12 Identify the following examples… You will be shown a series of photos. Tell if each photo represents an item composed of an element, compound, mixture, or solution.Review:An element contains just one type of atom.A compound contains two or more different atoms joined together.A mixture contains two or more different substances that are only physically joined together, not chemically.A solution is a mixture where all the substances are mixed together evenly.
41 Let’s Review!Match each diagram with its correct description. Diagrams will be used once. For each number write the name (For example: Pure Element) and draw the picture that matches. You do not have to write the definition.
43 COPY THE EXAMPLES INTO YOUR WORKBOOK!! Let’s Review….a little bit more Classify each of the following as elements (E), compounds (C), mixtures (M), or solutions (S). Write the letter X if it is none of these.COPY THE EXAMPLES INTO YOUR WORKBOOK!!___Pail of Garbage___Pizza___A dog___Dry Ice (CO2)___Ammonia (NH3)___Baking Soda (NaHCO3)___Kool-aid___Titanium (Ti)___Salt (NaCl)___Iced Tea___Energy___Gold (Au)
