Tonight's homework is to complete CW 94B. See below.
1a. Write one example of a chemical reaction.
1b. Draw a circle around the reactants.
1c. Draw a rectangle around the products.
1d. Describe what is actually happening in the reaction that you wrote out. Be specific and use details.
2. Look carefully at the following chemical reactions and determine whether they are synthesis or decomposition reactions.
a. 2H2N2 → 2H2O + O2 ____________________
b. CO2 + H2O → H2CO3 ____________________
c. N2 + 3H2 → 2NH3 ____________________
d. 2 H2O + energy → 2H2 + O2 ____________________
e. 6 H2O + 6 CO2 + energy → C6H12O6 + 6 O2 ____________________
f. 2 Fe + 3 O2 ← Fe2O3 ____________________
g. CaCO3 ← CaO + CO2 ____________________
3. For each of the examples in #2 above, draw a circle around each of the reactants and draw a rectangle around each of the products.
4. How do chemical reactions connect to homeostasis?
