3. What atom is in most living things on Earth? Carbon
$200
What atom is in most living things on Earth?
Carbon
Return

4. How do Covalent bonds form?
$400
How do Covalent bonds form?
Electrons are shared between (non-metalic) atoms
Return

5. Metal atom lose electron to non-metal atom
$600
How do Ionic bonds form?
Metal atom lose electron to non-metal atom
Return

6. $800 What are hydrogen bonds & how do they form?
Hydrogen bonds form between hydrogen and bigger atoms (like oxygen) because electrons are unevenly shared between them
Electrons spend more time on the oxygen side
Return

7. $1000 What is a molecule? What type of chemical bond forms a molecule?
Two or more atoms covalently bonded together
Return

8. Hydrogen (H) and Oxygen (O); Covalent bonds
$200
Name the atoms that make up a molecule of water and name the type of chemical bond that holds them together.
Hydrogen (H) and Oxygen (O); Covalent bonds
Return

9. Oxygen side is negative, Hydrogen side is positive
$400
Water molecules are polar. Which side of the water molecule is negative? Which is positive?
Oxygen side is negative, Hydrogen side is positive
Return

10. What is the difference between a solute and a solvent?
$600
What is the difference between a solute and a solvent?
solute dissolves in solvent like sugar dissolves in coffee
Return

11. $800 What are cohesion and adhesion?
Cohesion is attraction between the same thing, adhesion is attraction between different things
Return

12. $1000 What are solutions and suspensions?
solutions are evenly mixed together (distributed) like salt water, while suspensions are not even mixed and parts can settle out (like blood cells settle to the bottom of a test tube when the blood stops moving)
Return

13. Carbohydrates, Lipids, Proteins, Nucleic Acids
$200
Name the four Macromolecules:
Carbohydrates, Lipids, Proteins, Nucleic Acids
Return

14. $400
What organic compound (Macromolecule) is the main short energy source for living things?
Carbohydrates
Return

15. $600
Which macromolecule is the long term energy source and makes up cell membranes?
Lipids
Return

16. Nucleotides; store and transmit genetic information; e.g. DNA & RNA
$800
What are the monomers and functions of nucleic acids? Give two examples.
Nucleotides; store and transmit genetic information; e.g. DNA & RNA
Return

17. $1000
What are the monomers of Proteins? Give three examples of proteins functions:
Amino Acids
antibodies fight disease, enzymes make chem. reactions go faster, structural parts of muscle & bone, transport proteins move things thru the body-e.g. hemoglobin carries O2
Return

18. What are the monomers of carbohydrates? monosaccharides
$200
What are the monomers of carbohydrates?
monosaccharides
Return

19. How are reactants and products different?
$400
How are reactants and products different?
Reactants are before the arrow  Products are after the arrow
Reactants are present at the beginning of a chemical reaction, they are the “ingredients” for the reaction; Products are made at the end of the reaction
Return

20. Reactants: H2O2 (hydrogen perioxide)
$600
Name the reactants & products in this chemical reaction: H2O2  H2O + O2
Reactants: H2O2 (hydrogen perioxide)
Products: H2O & O2 (water & oxygen gas)
Return

21. $800 What kind of Macromolecule are polysaccharides? carbohydrates
Return

22. What are the reactants in enzyme aided chemical reactions called?
$1000
What are the reactants in enzyme aided chemical reactions called?
substrates
Return

23. What kind of Macromolecule are enzymes? proteins
$200
What kind of Macromolecule are enzymes?
proteins
Return

24. activation energy (energy needed to get the reaction started)
$400
What is the energy called that is needed to get a chemical reaction started?
activation energy (energy needed to get the reaction started)
Return

25. $600
What is the substance called that makes the rate of chemical reactions in living things happen faster and with less energy?
enzymes
Return

26. $800
What is the substance called that makes the rate of any chemical reaction happen faster and with less energy by lowering the activation energy needed?
catalyst
Return

27. $1000 Name 2 things (factors) that will affect how Enzymes work:
temperature, pH & concentration of enzyme of substrates
Return

28. What is the Universal solvent? Water (H2O)
$200
What is the Universal solvent?
Water (H2O)
Return

29. What is the pH range for acids? What is the strongest acid?

What is the pH range for acids? What is the strongest acid?
Acid pH range is 0-6.9, strongest acids: pH 0
Return

30. $600 What is the pH range for bases? What are the strongest bases?
base pH ranges from 7.1 – 14 and the strongest bases are pH 14
Return
