Row 1, Col 1 What is the Periodic Table? If it is an element, it is found on this chart.

1,2 What is chemically combined in a specific ratio? A compound is 2 or elements combined in this way. (Hint: there are TWO parts to this)

1,3 What is heterogeneous? A bag of gummy bears is this type of mixture.

1,4 What is new matter with new properties? This is created after a chemical reaction occurs.

2,1 What is a metalloid? A mysterious sample is shiny and it will conduct some electricity but it is not ductile. This is the category of elements that the sample would best fit in.

2,2 What is 3? This is the chemical formula for acetone, OC(CH 3 ) 2. This is the number of Carbon atoms in the formula for acetone.

2,3 What is the lemonade powder? In a solution of lemonade powder and water, this is the solute.

2,4 What is 2 Nitrogen atoms and 6 Hydrogen atoms? N 2 + 3H 2  2NH 3 This is the number of and types of atoms in the reactants of this chemical equation.

3,1 What is Potassium? I went to the local vitamin store to pick up this supplement, it is signified with the symbol, K.

3,2 Compounds are chemically combined and mixtures are physically combined This is the difference between a compound and a mixture.

3,3 What is a colloid? The particles in this type of mixture are large enough to scatter light but not heavy enough to settle out.

3,4 What is electrolysis? This is what it is called when we use electric current to break down a compound.

4,1 What is density? This characteristic property described as the ratio of a samples mass over volume can be used in determining the identity of an element.

4,2 What is chemically? Compounds can only be broken down in this way.

4,3 What is concentration? This describes the amount of solute dissolved in an amount of solvent.

4,4 What are characteristic properties? Flammability and reactivity are examples of this type of chemical property that are the same no matter the sample size.

5,1 What is magnetism? Physical PropertySubstance 1Substance 2 Boiling Point1,310°C1,004°C ColorSilvery whiteSilvery White OtherMagneticNon-magnetic This is how we can tell that substance 1 and 2 are not the same.

5,2 What are CH 4 and 5O 2 (methane and oxygen)? CH 4 + 5O 2  CO 2 + 2H 2 O These are the reactants.

5,3 What is a centrifuge? This machine is used to separate mixtures according to their densities.

5,4 What is bubbling, foaming, smell, color change, hot gas formed, or light given off? These are 3 examples of things that may occur to signify that a chemical change has taken place.
