  3. What is the name of the compound with the formula H2SO4 ? Sulfuric Acid

  4. What are the products from the following equation? LiOH + H2SO4  ?? 2H2O and Li2SO4

  5. Name this molecule and give the molecular (chemical) formula: Cyclohexane C6H12

  6. According to this graph, if you dissolved 100g of KNO3 in 100g of water at 50ºC, how much would be left dissolved? 20g

  7. Which two of the following molecules are isomers? a b c d A and D

  8. What is the Reqv if 2 10 Ω resistors are connected in series with a 2V battery? 20 Ω

  9. Three 5V lights are connected in parallel.Each light has a normal brightness.What is the overall voltage supplied by the battery? 5 volts

  10. An appliance with a resistance rated at 15Ω is connected to a 120V outlet. How much current does it draw? I = V/R = 120/15 = 8 Amperes.

  11. DAILY DOUBLE

  12. A circuit of three 10Ω resistors is connected in series. If it is connected to a 12 V battery, how much current is a) leaving from the battery and b) travelling through one of the resistors? What is a) 0.4 A and b) 0.4 A.

  13. Given the following circuit calculate Reqv: Reqv= ??Ω R1= 3 Ω R2= 3 Ω R3= 3 Ω R4= 3 Ω Reqv = 4Ω

  14. What energy conversion is taking place when a log is burned? Chemical potential  thermal and radiant

  15. A book has a mass of 1.5kg. What is its weight? 15N

  16. A roller coaster starts at 25m above ground to gain 50,000J of gravitational potential energy. What is the mass of the roller coaster? 200 kg

  17. A truck with a mass of 500kg carrying 2 men who are 75kg each is travelling at 10m/s. How much kinetic energy does the truck have? 32,500J

  18. A 500g basketball is thrown 1.5m in the air. How much kinetic energy does it have when it hits the ground if air resistance is negligible? 7.5J

  19. What is the velocity of a 5,000kg elephant that has 10,000J of energy? 2m/s

  20. 3 students are pushing against the door to MTB. The door is not moving because Mr. Assaad is pushing on the other side with 39N of force. How much force is each student using if each student is pushing equally? 13N

  21. An alligator’s tail has a mass of 700kg. How fast is the tail accelerating when it hits with a force of 17,500J? 25m/s

  22. List Newton’s 3 Laws of Motion • Inertia (objects at rest tend to stay at rest, objects in motion tend to stay in motion) • Force = mass * acceleration • Every action has an equal and opposite reaction

  23. List the action reaction force pairs: Man pushes back with foot, boat pushes man forward

  24. What is “wrong” with Newton’s first law (why don’t we seem to see it in action when objects are moving?) Objects in motion come to a stop because of friction – energy converted to heat, light and sound

  25. If a car is accelerating and then stops accelerating (acceleration becomes 0m/s2), what happens to the car? a) Slows b) Continues to move at a constant speed c) Goes faster d) Stops completely b) Continues to move at a constant speed (is travelling at a certain speed but speed is no longer changing)

  26. Who has a faster acceleration? A) Mohammad is in a rocket and goes from rest to 50m/s in 40s.B) Peter is running and goes from rest to 5m/s in 3.5s. Peter

  27. If your car is going 5m/s, how fast is it going in km/hr? 18

  28. At what point was the car stopped? From 0-3s (and after 10s)

  29. Graph constant speed, using the appropriate units.

  30. FINAL JEOPARDY What is the average speed of a car that travelled 3km at 5m/s and 6km at 4m/s? 3000m/5m/s = 600s6000m/4m/s = 1500s(3000+6000)m/(600+1500)s =9000m/2100s= 4.3 m/s

  31. GOOD LUCK!
