H 2 O (liquid)  H 2 O (gas) Same molecule on each side of the equation – structure or identity stayed the same One side has liquid water, the other side has gaseous water – phase change No bonds were broken – PHYSICAL CHANGE CH 4 + 2O 2  CO 2 + 2H 2 O Same elements on each side of the equation – BUT structure or identity has changed Different compounds have formed on each side of the equation There have been chemical bonds broken, atoms rearranged, & new bonds created – CHEMICAL CHANGE

Element Compound MixtureSolution

 MUST be on the Periodic Table OF ELEMENTS  Pure substances made of only one type of atom  Combine to form all other types of matter  Examples:  Silver  Calcium  Oxygen

 Single atoms of ONE pure element  Molecules of ONE pure element

 Two or more elements combine during a chemical reaction  Must be combined in specific ratios  Chemical Change/Reaction  Examples:  Water  Salt  Sugar

 2 or more ELEMENTS that are CHEMICALLY bonded to one another

What is evidence that a chemical reaction is happening again?

 Combines 2 or more substances without producing a chemical reaction  NOT the same throughout - heterogeneous  Basic mixtures can be separated easily  Examples:  Soil  Fruit salad  Physical Change

 2 or more SUBSTANCES MIXED together, but NOT chemically bonded.

 A type of HETEROGENEOUS MIXTURE – different throughout  Particles will not dissolve, (insoluble) or are suspended  Examples:  Italian dressing  Snow globe

 A type of HOMOGENOUS MIXTURE - same throughout  Can be solids, liquids or gases  Solute- substance being dissolved  Solvent- substance doing the dissolving  Examples:  Salt water  Lemonade  Physical Change Salt = Solute Water= Solvent Salt Water= Solution

 It is also a mixture of 2 or more SUBSTANCES, but the particles will be evenly distributed throughout (homogenous)

 A type of HOMOGENEOUS SOLUTION  Have an “in between” texture  Examples:  Jell-O  Pudding

 Take a look at the homework…make corrections if they are wrong!

 Make sure you are on the Double Reaction Lab Quiz side of the paper!  Double Reaction Lab Quiz + Sum It Up = FORMAL GRADE

Group Roles Leader: Reads the directions, keeps group on task and following directions Materials/Clean Up: collects, returns, cleans and disposes of materials Data Discussion Leader: Ensures there is a conversation about each question to share information. Quality Management: Ensures every student has detailed quality answers written in complete sentences using scientific language & turns their lab guide in with their name on it!

 Quick one question assessment to make sure you understand the difference between an element, compound, mixture and solution  MAKE SURE YOUR “QM” CHECKS FOR NAMES ON EACH SHEET AND TURNS THEM IN TO THE BASKET!

 Take a Science Textbook off the shelf  Write your name in it  While you work on your Study Guide Part 1, I will come around to record the number you have taken  THEN…TAKE IT HOME AND LEAVE IT THERE!

 Parent acknowledgement of your grade!  Chemistry Test 2 coming up soon!  Finish Study Guide Part 1

 Update your Table of Contents  Write your homework – leave it to be stamped  Get your homework out to be checked – it should be taped into page 23!  Look at the last question on the homework & discuss your answer with your group. DateSession # ActivityPage # 10/2- 10/3 14 BIG QUESTION Quick Writes Unknown Substances Chart & Quick Write 4 25 Study Guide Part 2 26

 In your paper bag there are 4 similar objects.  Choose 1 person to stick their hand in the bag WITHOUT looking…they will have to pull out what I ask for!  How did you know you had the right object?

 If you have one or more unidentified substances, what could you do to start identifying them? ANSWER: By their physical & chemical properties!

 DID YOU HAVE… ◦ Compound ◦ Two elements bonded ◦ Carbon & Hydrogen ◦ Flammable ◦ Covalent bond ◦ 2 nonmetals ◦ Full valence shell-Hydrogen 1 valence, Carbon 4 valence ◦ WHAT ELSE? Methane – CH 4

 DID YOU HAVE… ◦ Shiny ◦ Metallic ◦ Flammable ◦ Gives off light ◦ Silver/gray ◦ Malleable ◦ Looks sharp ◦ Temperature change ◦ WHAT ELSE? Magnesium

 I’m thirsty and need water to survive, but have 3 beakers of clear liquid…how can I start identifying what they are so I can have something to drink?  Discuss with your group & record what your options are/steps you would take to identify the water!

 You will get a chart with 10 UNKNOWN substances.  BUT, you also have 2 copies of a list of KNOWN substances and some of their properties.  Use the list of KNOWN substances to figure out what your UNKNOWN substances are.

 There is a deposit of silver mixed with sulfur. Silver has a density of 10.5 g/cm 3 and a melting point of 962 degrees Celsius. Sulfur has a density of 2.07 g/cm 3 and a melting point of 115 degrees Celsius. How can these physical properties be used to separate silver and sulfur?  Heat the mixture until the sulfur melts. The solid silver will sink to the bottom because it is denser and can be removed leaving the liquid sulfur behind.
