Think about what you've learned about how particle motion is related to temperature.

Select all of the statements that are true.

1. The average kinetic energy of the particles in a substance determines the

substance's temperature.

2. If the particles in two pure substances have the same average speed, the

substances can have different temperatures.

3. When two substances have the same temperature, all of the particles in

both substances are moving at the same speed.

4. How fast a substance's particles are moving determines how hot or cold

the substance is.

Write the complete balanced equation for the reaction between lead (iv) oxide (pbo2) and water (h2o).

Answer the questions about this reaction: nai(aq) + cl2(g) → nacl(aq) + i2(g) write the oxidation and reduction half-reactions: oxidation half-reaction: reduction half-reaction: based on the table of relative strengths of oxidizing and reducing agents (b-18), would these reactants form these products? write the balanced equation: answer options: a. 0/na -> +1/na+1e- b. nai(aq) + cl2(g) → nacl(aq) + i2(g) c. +1/na+1e- -> 0 /na d. -1/2i -> 0/i2+2e- e. no f. 4nai(aq) + cl2(g) → 4nacl(aq) + i2(g) g. 2nai(aq) + cl2(g) → 2nacl(aq) + i2(g) h. 4nai(aq) + 2cl2(g) → 4nacl(aq) + 2i2(g) i. nai(aq) + cl2(g) → nacl(aq) + i2(g) j. 0/cl2+2e -> -1/2cl- k. yes
