Homework help from our online tutors - BrainMass.com

Hello, I need help figuring these problems out! Thanks :-)

1. Balance the following equations:

a. P4(s) + 02(g) --> P4O10(s)
b. Fe2O3(s) + C(s) ----> Fe(s) + CO(g)
c. C4H10(l) + 02(g) --> CO2(g) + H2O(g) + energy

2. Aluminum metal reacts with bromine gas to produce aluminum bromide.
a. Write a balanced equation, including states of matter.
b. What type of chemical reaction is this?

3. Aqueous aluminum sulfate reacts with aqueous potassium hydroxide to produce aqueous potassium sulfate and an aluminum hydroxide precipitate.
a. Write a balanced chemical equation, including states of matter
b. What type of chemical reaction is this?

4. In the following reactions, identify what is oxidized, and what is reduced.
a. 2Li(s) + F2(g) --> 2LiF(s)
b. Cl2(g) + 2KI(s) --> 2KCl(aq) + I2(g)

5. In one of the metabolic reactions in the citric acid cycle, which provides energy for ATP synthesis, succinic acid is converted to fumaric acid.

C4H6O4 (succinic acid) -----> C4H4O4 + 2H (fumaric acid)

The reaction is accompanied by a coenzyme, falvin adenine dinucleotide (FAD).

FAD + 2H --> FADH2

a. is succinic acid oxidized or reduced?
b. is FAS oxidized or reduced?
c. Why would the reactions occur together?
