Q6. Click on the "Combust Methane" option button on the top right of the applet.

Follow the same steps to balance this equation. What is the balanced equation for

the reaction of "CH." with "0₂" to form "CO₂" and "H₂O"? What is the name of each of

the compounds in the equation?

Q7. What is the balanced equation for the reaction of Al and O₂ to form Al₂O₂? What

is the name of each of the compounds in this equation? What type of reaction is

this?/nQ8. Answer all parts of this question as they relate to the chemical equation:

Zn + 2 HCI ---> ZnCl₂ + H₂

1. What is the name of each compound in this equation?

2. What type of reaction is this?

3.

Is this equation balanced? Show your work and explain why it is or

is not balanced.

Q9. Answer all parts of this question as they relate to the chemical equation:

FeS + HCI ---> H₂S + FeCl₂

1. What is the name of each compound in this equation?

2. What type of reaction is this?

3.

Is this equation balanced? Show your work and explain why it is or

is not balanced./nQ10. Look back at the "Collision Theory of Chemical Reactions" applet. Click on the

"Reset to high energy initial setting." option box and then click "Run". Watch the

simulation at "fast" speed for at about one minute. Click on the "Reset to low energy

initial setting." option box and then click "Run". Watch this simulation at "fast" speed

for about one minute. Answer the following parts of this question about what you

observed.

1. What did you observe in each of the two simulation runs?

2. What differences did you see between each of the two simulation runs?

3. Which of the factors that affect rates of reaction could explain the

difference between these two runs? Explain how the factor(s) apply to

the simulation runs and what effect it/they had on the runs.
