100
This is how many atoms are needed to make a molecule.
What is two or more?
100
The periodic table is a list of all of these.
What are elements?
100
These are the four properties of matter.
What are mass, weight, density, and volume?
100
As water is heated, the motion of molecules will generally (1) increase (2) decrease (3) stay the same
What is (1) increase.
100
This activity involves ONLY a physical change. (1) grinding coffee beans (2) baking cookies (3) acid bubbling on a rock (4) exploding fireworks
What is grinding coffee beans?
200
This is what is needed to make a compound.
What is two or more different atoms?
200
The periodic table is arranged according to the number of these in each element.
What are protons?
200
You transfer liquid from one graduated cylinder into a second graduated cylinder. After transferring, you will have (1) less mass and more volume (2) less mass and the same volume (3) the same mass and more volume (4) the same mass and the same volume
What is (4) the same mass and the same volume
200
In a solid, molecules are generally (1) farther apart than in a gas or a liquid (2) farther apart than in a gas but closer than in a liquid (3) closer together than in a gas or a liquid (4) closer together than in a liquid but farther than in a gas
What is (3) closer together than in a gas or a liquid
200
As a candle burns, THIS type of change turns chemical energy stored in the wax into heat and light.
What is chemical change or chemical reaction?
300
These are the three parts that make up all atoms.
What are protons, neutrons, and electrons?
300
This group of elements are gases in group 18 and they do not like to combine with other elements.
What are noble gases?
300
This is one way you can find the volume of a block.
What is... -multiply LxWxH -use displacement (water)
300
The relationship between temperature and speed of molecules in a gas is (1) as temperature increases, speed decreases (2) as temperature increases, speed increases (3) as temperature increases, speed doesn't change (4) as temperature increases, speed is unpredictable
What is (2) as temperature increases, speed increases
300
This is evidence that a chemical change or reaction has occurred.
What is... -bubbles/gas -heat -light -color change -new substance
400
This is what is found in the nucleus of an atom.
What are protons and neutrons?
400
Halogens are all in this group on the periodic table.
What is group 17?
400
This property, the ratio of mass to volume, explains why a styrofoam block is easier to lift than an iron block.
What is density?
400
This type of energy, from the motion of particles, causes changes in the state of matter (liquid, solid, gas).
What is kinetic energy or thermal energy?
400
This is why liquid evaporating into a gas is an example of physical change NOT a chemical change.
What is... -change of state -no new substance is formed -change can be reversed -etc.
500
Hydrogen (H) and oxygen (O) are examples of.... (1) molecules (2) compounds (3) elements
What is (3) elements?
500
This is one group of elements that is highly reactive and very unstable.
What are alkali metals (group 1) or alkaline earth metals (group 2)?
500
This property of oddly-shaped objects can be measured using water and a graduated cylinder.
What is volume?
500
This state of matter has more kinetic energy than the other two.
What is a gas?
500
Name one example of a chemical change AND the evidence you see during this change.
What is [any chemical change] because I see [any viable evidence].
