Welcome! Please take out your materials for the day While I take attendance, tell me about your weekend.

Chemistry Review Chemistry is the study of how matter interacts to form different substances. These substances can be atoms, molecules, or materials. Chemistry is used in many professions such as: cooking, cosmetic production, engineering, and ecology

Vocab review In your notebooks, write down as many vocabulary words you can remember from Chemistry

Important Vocab Atom= Electron= Neutron= Proton= Molecule= Reaction= Equation= The smallest partice of matter A negatively charged particle in an atom responsible for bonding A particle with no charge that exists in the nucleus of an atom A postively charged particle that exists in the nucleus of an atom A grouping of bonded atoms When two or more atoms with compatible electron configurations combine to form a single entity A mathematical expression used to tell the story of molecular recombination

What is matter? Matter is anything that has mass and takes up space

Physics Review Newton’s 1st law An object at rest will stay at rest until acted upon by a force Newton’s 2nd law Force equals mass X acceleration Newton’s 3rd law Every action has an equal and opposite reaction, OR Energy (or matter) is neither created nor destroyed.

Why do Equations need to be balanced? Because matter is neither created nor destroyed, For example, If we have two pieces of bread and 3 slices of ham, we would have one ham sandwich. Our equation would be: 2b + 3 h = 1 2b3h ** same # of atoms on both sides** The expression we use to tell the story of the reaction needs to show the same # of atoms on both sides

In your groups, begin to work on page 1 of the “Balancing Chemical Reactions” packet. If you think you are done, compare answers with another group Do not move on to page 2 until we are all finished Use your notes to help  Group Practice.

#1 Only work in your table groups for now Molecule Models! Working in groups, please abide by the following expectations: #1 Only work in your table groups for now #2 DO NOT EAT THE CANDY #3 When you think you have balanced the first equation correctly, write down the steps you took in your notebook

Share your Process Step 1: Step 2: Step 3: Balanced Equation:

Share your Process Step 1: Step 2: Step 3: Balanced Equation:

More Group Practice: Switch with another group or pair and compare answers until your answers match… Using your Notebooks as a workspace, balance the 10 equations listed on the practice handout **Using a pencil might be the best idea for this activity** Only write your final answer on the handout

LET’S REVIEW SOME CONCEPTS Yellow Is the color of gold, butter and ripe lemons. In the spectrum of visible light, yellow is found between green and orange. Blue Is the colour of the clear sky and the deep sea. It is located between violet and green on the optical spectrum. Red Is the color of blood, and because of this it has historically been associated with sacrifice, danger and courage. Yellow Is the color of gold, butter and ripe lemons.
