| Question | Answer |
| WHAT ARE THE PARTS OF AN ATOM? | THE NUCLEUS IS MADE OF NEUTRONS AND PROTONS ELECTRONS ROTATE AROUND THE NUCLEUS |
| WHAT IS A NON POLAR COVALENT BOND | ELECTRONS SHARED EQUALLY. EXAMPLE: HYDROGEN BONDS |
| WHAT IS A POLAR BOND? | ELECTRONS SHARED UNEQUALLY. EXAMPLE: WATER |
| WHAT IS AN IONIC BOND? | WHEN HIGH ELECTRO-NEGATIVITY STRIPS VALENCE AWAY FROM ANOTHER ATOM. EXAMPLE: SODIUM CHLORIDE |
| WHAT IS A HYDROGEN BOND? | HYDROGEN BONDS OCCUR WHEN A POSITIVE HYDROGEN BOND ATTRACTS TO A NEGATIVE ATOM. EXAMPLE: WATER, DNA |
| WHAT IS A CHEMICAL REACTION? | REACTIONS OCCUR WHEN TWO OR MORE MOLECULES INTERACT AND THE MOLECULES CHANGE. |
| WHOS GOING TO ACE THIS TEST TODAY? | YOU OF COURSE! KEEP WORKING HARD, YOU ARE DOING GREAT! :) |
| HOW DOES A HYDROGEN BOND RELATE TO WATER? | HYDROGEN ATTRACTS THE H ATOMS TO THE O ATOMS. HYDROGEN BONDS ARE THE GLUE OF WATER! |
| WHAT ARE THE PROPERTIES OF WATER? | -WATER IS LIQUID AT ROOM TEMP; drinking, bathing, cooking -TEMP OF WATER RISES AND FALLS SLOWLY; prevents drastic changes -HIGH HEAT OF VAPOR; body doesnt overheat -ICE IS LESS DENSE THAN LIQUID WATER; so ice floats -WATER MOLS ARE COHESIVE; blood vessels |
| WHAT IS AN ACID? | INCREASES THE HYDROGEN CONCENTRATION OF A SOLUTION |
| WHAT IS pH? | POWER OF HYDROGEN! |
| WHAT IS BASE? | REDUCES THE HYDROGEN ION CONCENTRATION OF A SOLUTION |
| DEFINE SOLUTE | THE MATTER THAT DISOLVES IN SOLUTION |
| DEFINE SOLVENT | THE MATTER DISSOLVING SOLUTE |
| DEFINE SOLUTION | 2 OR MORE SOLVENTS MIXED TOGETHER AND UNIFORMLY DISPERESED. MAINLY THE RESULT OF FLUID, SOLID OR GAS BEING DISSOLVED IN A LIQUID. |
| WHY IS CARBON IMPORTANT FOR LIVING ORGANISMS? | CARBON STICKS TO ITSELF. CREATING LONG CHANGES OF COMPLEX MOLECULES, IMPORTANT IN THEIR OWN FUNCTIONS. ALL LIFE ON EARTH IS BASED ON CARBON. |
| WHAT IS THE FUNCTION AND SUBUNIT OF CARBOHYDRATES? | THE FUNCTION OF CARBS IS A SHORT TERM ENERGY STORAGE. SUBUNIT: SIMPLE SUGARS |
| WHAT IS THE FUNCTION AND SUBUNIT OF NUCLEIC ACID? | TO STORE AND TRANSMIT GENETIC INFORMATION. EXAMPLE: NUCLEOTIDES |
| WHAT IS THE FUNCTION AND SUBUNIT OF PROTEIN? | TO SUPPORT ENZYMES AND TRANSPORT DEFENSE, TO PUT HORMONES IN MOTION. SUBUNIT: AMINO ACIDS |
| WHAT IS THE FUNCTION AND SUBUNIT OF LIPIDS? | CONTAIN MORE ENERGY PER GRAM THAN OTHER BIOLOGICAL MOLECULES. SUBUNIT: FATTY ACIDS |
| HOW IS DNA AND RNA ALIKE AND DIFFERENT? | DNA AND RNA ARE BOTH MADE UP OF POLYNUCLEOTIDE STRANDS. DNA HAS 2 STRANDS. RNA ONLY HAS 1. |
