Chemical Bonds
What is the speed at which reactants turn into products is known as what?
Reaction rate
Which of the following is a mixture that has particles that cannot be seen even with a microscope?
Solution
Which of the following is defined as the rate at which an object is moving?
speed
Which of the following is the definition for the law of conservation of momentum?
If there is no external force on a system, the momentum on the system remains the same
Is the amount of kinetic energy an object has more dependent on its mass or velocity?
velocity
What makes an acid or a base strong?
It will completely dissociate in water.
Which of the following is defined as a pure substance made up of only 1 type of atom?
Element
Which of the following is defined as the rate at which an object is moving in a certain direction?
velocity
A bullet is fired from a gun. If we look at the entire system of the bullet and the gun, is momentum conserved?
yes
A 8 kg car tire is rolling down a hill at 10 m/s. What is the kinetic energy of the car?
400 J
Which of the following is a definition for a buffer?
A solution that resists a change in pH when an acid or a base is added
Which of the following is made of parts that are chemically bound together?
Compound
One way to change your velocity and give yourself an acceleration is to speed up or slow down. What is the other way?
Change your direction
Newton's second law states that if no net force is exerted on a system, no acceleration occurs. Does this mean that there is no change in momentum as well?
Yes, no acceleration means no change in velocity, which means no change in momentum
What type of potential energy depends on the the ability of a spring to be stretched or compressed?
Elastic potential energy
What two products are created during neutralization reaction?
Water and a salt
Which of the following consists of everything visible in the universe that takes up volume?
Matter
What quantity causes objects to fall to the ground?
Gravity
A 9 kg mass is moving to the right with a velocity of 14 m/s. A 12 kg mass is moving to the left with a velocity of 5 m/s (make this negative). Assuming that these two balls have ahead on collision and stick together, what will be the final velocity of the combination?
3.1 m/s
Which of the following is not one of the types of potential energy?
Kinetic energy
Which of the following is the part doing the dissolving in a solution?
Solvent
Which of the following are composed of distinct parts that can be separated?
Heterogeneous mixture
On a speed vs. time graph, what does the slope of the graph tell you?
Acceleration
A Passenger car (m = 10.0 kg) and a flat car (m = 7.5 kg) collide and stick together. The Passenger car was initially traveling at 3.5 m/s right and the flat car was initially traveling at a velocity of 2.2 m/s left (make this negative). What is the final velocity of the two car system?
1.1 m/s
What type of potential energy is stored in the bonds between particles?
Chemical potential energy
