2. List the subatomic particles and their charges.
Answer: What is protons- have a positive charge; neutrons- have a no charge; and electrons- have a negative charge?

3. List where the 3 subatomic particles can be found in an atom.
Answer: What is protons and neutrons are found in the nucleus and electrons are found orbiting the nucleus?

4. Subatomic Particles 300
This is also known as a pure substance that consists entirely of one type of atom.
Answer: What is an element?

5. Subatomic Particles 400
If Carbon has 6 protons but 7 neutrons, name the isotope.
Answer: What is Carbon-13? (Add protons and neutrons = 13; normally C has a mass # of 12…)

6. Subatomic Particles 500
Having different numbers of neutrons has what effect on isotopes?
Answer: What is changes mass number and still exhibits all chemical properties of the element.

7. Another name for this structure is a molecule.
Bonds100
Another name for this structure is a molecule.
Answer: What is a chemical compound?

8. Electrons (-) being shared between atoms.
Bonds 200
Electrons (-) being shared between atoms.
Answer: What is a covalent bond?

9. Bonds 300
When molecules are close together they create an attraction (either + or -) between oppositely charged regions of nearby molecules.
Answer: What is van der Waals forces?

10. Describe how an ionic bond can form.
Bonds 400
Describe how an ionic bond can form.
Answer: What is one atoms easily loses an electron (-) while another atom can easily gain an electron (-).

11. Bonds 500
Describe how are ionic bonds and van der Waals forces similar/ different.
Answer: What is they are similar because particles are held together by attraction, but they are different because the attraction is stronger with ions than with molecules?

12. Sketch a water molecule.
Answer: Oxygen attached to two hydrogen atoms.

13. Water 200
What is the difference between water molecules being attracted to each other and water molecules being attracted to a glass container?
Answer: What is cohesion is water molecules attracted to each other and adhesion is water molecules attracted to a glass container?

14. In sea water what is the solute and what is the solvent?
Answer: What is the salt is the solute (part that dissolves) and the water is the solvent (substance solute dissolves in)

15. Sketch water and label its polarity (+ and – ends).
Answer: H end is slightly + and O end is slightly -

16. Water 500
A glass of lemonade made from a powder mix and Italian dressing; describe which is a solution and which is a suspension.
Answer: What is lemonade is a solution- powder dissolves but takes up space in the glass and Italian dressing is a suspension- you can see different ingredients ?

17. OrganicCompounds100
This forms as a result of polymerization of a monomer (“single part”) and a polymer (“many part”).
Answer: What is a macromolecule?

18. OrganicCompounds200

Answer: What is Caron dioxide (CO2) and water (H2O) are reactants and sugar (C6H12O6) and oxygen (O2) are products.

23. Chemical reactions affect bonds.
Answer: What is chemical reactions change/ rearrange the chemical bonds.

24. Describe the role of an enzyme in a chemical reaction.
ChemicalReactions300
Describe the role of an enzyme in a chemical reaction.
Answer: What is enzymes speed up a chemical reaction, acting like a catalyst.

25. ChemicalReactions400
In a chemical reaction, this inhibits the enzyme which makes the enzyme less effective.
Answer: What is a base was added?

26. ChemicalReactions500
Describe the difference between chemical reactions and the Energy absorbed or released.
Answer: What is chemical rxn that release energy are spontaneous and chemical rxn that absorb energy need an energy source to start the reaction.
