Monday Balance the following equations: 1. H2 + O2 --> H2O 2. H2O2 --> H2O + O2 3. Na + O2 --> Na2O 4. N2 + H2 --> NH3 5. P4 + O2 --> P4O10

Tuesday – State whether or not the statement is True or False 1. The general form of a chemical equation is Reactants = Products. 2. The symbol CO2 represents two molecules of carbon monoxide. 3. The symbol 2H2 represents two atoms of hydrogen. 4. Coefficients are used to balance chemical equations. 5. In balancing chemical equations, you should use the smalles t subscripts possible. 6. The number of each type of molecule must be the same on both sides of a chemical equation. 7. Changing coefficients changes the substances involved in a chemical reaction. 8. Chemists use a standard method to represent chemical reactions. 9. The chemical equation H2CO3 → H2O + CO2 is balanced. 10. Water is the reactant in the chemical equation H2O → H2 + O2.

Wednesday- True or False The products and reactants of a chemical reaction have different atoms. All chemical reactions are reversible. Rusting is an example of a chemical change. Condensation is a type of chemical reaction. A change in temperature is a common sign of a chemical reaction.

Thursday 1. one reactant breaking down into two or more products 2. two reactants changing places in two compounds 3. two reactants combining to form a single product 4. one element replaces another element in a compound Terms a. synthesis reaction c. decomposition reaction d. single replacement reaction e. double replacement reaction

Friday A(n) __________ reaction is represented by the general equation A + B → C. A(n) __________ reaction is the reverse of a synthesis reaction. The general equation A + BC → B + AC represents a(n) __________ reaction. A(n) __________ replacement reaction produces two new compounds. Sign bus driver cards on the back counter.
