A student is balancing an equation in her chemistry class. What fact is she using to check her work?
The number of atoms on each side of the reaction arrow must be different.
The number of atoms on each side of the reaction arrow must be the same.
The number of molecules on each side of the reaction arrow must be the same.
The number of elements on each side of the reaction arrow must be the same.
Antoine Lavoisier is credited with the Law of Conservation of Mass. He was working with metal mercury and when he heated it, the product had more mass than it started with. He performed the experiment again but in a sealed jar. The mass of the experiment before and after heating had not changed. What explains these results?
There was no way for gas to enter the jar.
The oxygen used in the combustion reaction was not considered in the first trial.
The mass of the jar was not considered.
Metal mercury only works as a solid.
A student placed 6.0 grams of baking soda into a small balloon. The mass of the balloon and soda was measured at 7.0 grams. Next, the student poured a measure of vinegar into a Florence flask that had an empty mass of 100 grams. After the balloon was stretched across the top of the flask, the student dumped the soda into the vinegar. A gas was formed by a chemical reaction that filled the balloon. After the reaction stopped, the student placed the flask with the filled balloon on a balance scale and it measured 125 grams.
What was the mass of the vinegar the student put in the flask at the start?
18 g
19 g
20 g
There is not enough information to correctly answer.
In the chemical equation, there are three Na atoms, three Cl atoms, and one Al atom represented on both sides. The equation is balanced. Which of the following best explains the fact that the equation is balanced?
laws of motion
law of gravity
law of conservation of mass
law of conservation of energy
Which statement about states of matter is most correct?
All states of matter have particles that are tightly packed and vibrate with little motion.
Only liquids and gases have little space between particles and are therefore not easily compressible.
Solids and gases both assume the shape of the container that they are placed in.
Gases are the only compressible state of matter.
A scientist obtains a microscopic view of a certain substance. She finds evidence of the molecules in a regular pattern that is rigid, the particles cannot slide past one another. She must be observing which state of matter?
solid
liquid
gas
plasma
Which of these conclusions about the unknown substance is best supported by these data?
It is a metal.
It will sink in water
It is a crystal.
Is is a gas.
A student wearing goggles, a lab apron, and thin latex gloves is best protected from —
cuts while working with a sharp scalpel
burns while handling a beaker of boiling water
burns while mixing chemicals in a test tube
shocks while working with live, low-voltage electrical wires
Students fill a beaker with 100 milliliters of water. They plan to heat the beaker for 25 minutes using a Bunsen burner. They plan to take a temperature reading every minute. After heating the beaker for 20 minutes, one lab group notices that there is less than 5 milliliters of water in the beaker. What should the group do?
Continue heating the beaker and taking temperature measurements for the full 25 minutes.
Turn off the burner and work with the measurements they already have. If necessary, repeat the experiment.
Wait until all the water is gone, then add some cold water to the beaker and continue taking measurements for the full 25 minutes.
Move the beaker to the countertop and continue taking measurements for the full 25 minutes.
Ted is jumping on a trampoline. The more he pushes on the trampoline, the higher he is thrust into the air. Which of Newton's laws is being demonstrated here?
Newton's Universal Law of Gravitation
Newton’s 1st Law
Newton’s 2nd Law
Newton’s 3rd Law
It takes more force to accelerate a school bus than it takes to accelerate a car. Which of Newton's laws is being demonstrated here?
Newton's Universal Law of Gravitation
Newton’s 1st Law
Newton’s 2nd Law
Newton’s 3rd Law
Tom is riding to school in his mother's car. When she makes a left turn, he leans to the right. Which of Newton's laws is being demostrated?
Newton's Universal Law of Gravitation
Newton’s 1st Law
Newton’s 2nd Law
Newton’s 3rd Law
If a car is making a turn at a high rate of speed, which of the following forces is necessary to safely stay on the road?
friction
gravity
momentum
inertia
The driver of a taxi stops to pick up a large family with many pieces of heavy luggage. Based on Newton's Second law of motion, the driver should expect that the taxi will —
take longer to travel the same distance
develope more stopping friction
requires less energy to keep moving
take longer to both accelerate and stop
The diagram represents the total travel of a teacher on Saturday. Which part of the trip is made at the lowest average speed?
Q
R
S
T
Interpret the speed versus time graph below.
A car moves forward at a constant speed, stops for a while, then continues forward again at a constant speed.
A car moves forward at a constant speed, stops for a while, then moves backward at a constant speed.
A car goes faster and faster, stops for a while, then accelerates again.
A car goes faster and faster, holds that speed for a while, then accelerates again.
When falling through the air, all objects will reach a top speed called terminal velocity. Is this good news or bad news for skydivers?
This is bad news because it limits the thrill of the skydive.
This is good news because it allows for parachutes to be pulled anywhere above a certain altitude.
This is bad news because skydivers can never catch up to other skydivers ahead of them.
This is good news because falling objects would leave craters otherwise.
When people talk about how fast they drive, what are they actually referring to?
Time
Speed
Velocity
Acceleration
If the gas pedal in a car is the accelerator, what device is the decelerator?
The reverse gear.
The brakes.
Second gear.
Neutral.
