The Metric System
What are chemistry and physics?
This is a measure of how much matter is in an object.
What is mass?
The smallest particle of a substance that still has the same properties of that substance.
What is a molecule?
Elements are arranged on the periodic table of elements in this order.
What is the ascending atomic number?
This forms when two or more elements combine and undergo a chemical change.
What is a compound?
This type of reaction involves changing substances into other substances.
What is a chemical change?
This is simply a change in position.
What is motion?
Anything that has mass and takes up space.
What is matter?
These are used to describe an object.
What are properties?
This is made of protons, neutrons, and electrons.
What is the atom?
The atomic mass of an element is found by averaging these two items.
What are an element's protons and neutrons?
This occurs when a substance appears to change, but its properties stay the same.
What is a physical change?
What is a double-replacement reaction?
This term is used to describe the speed and direction of an object.
What is velocity?
The basic unit of length in the metric system.
What is the meter?
What is a balance scale?
The number of electrons in an atom is equal to this.
What is the number of protons?
Elements are classified into these three categories.
What are metals, nonmetals, and noble gases?
A chemical formula shows how many and what kinds of these are in a compound.
What are atoms?
It is important that chemical equations have this characteristic.
What is balanced?
This is Newton's first law of motion.
What is an object at rest will tend to stay at rest and an object in motion will tend to stay in motion unless acted upon by an outside force?
The formula for the volume of an object.
What is length x width x height?
This method is used to find the volume of irregularly shaped objects.
What is the water displacement method?
The atomic number of an element is equal to this.
What is the number of protons?
Alloys are formed in this way.
What is the melting and combining of various metals?
These types of compounds have a low pH level and react with metals to form hydrogen. They also have a sour taste.
What are acids?
These are the four main types of chemical reactions.
What are synthesis, decomposition, single replacement, and double replacement?
This is Newton's 2nd law of motion.
What is F=ma
The basic unit of volume in the metric system.
What is a liter?
This tool is used to measure the volume of liquids.
What is a graduated cylinder?
The mass number of an element is found by.
What is the sum of protons and neutrons of that element?
Noble gases are called this term because they do not ordinarily react or combine with other elements.
What is inert?
A group of elements that behaves as if it were one element goes by this name.
What is a radical?
Electrolysis is an example of this type of chemical reaction.
What is decomposition?
This is Newton's 3rd law of motion.
What is every action has an equal and opposite reaction?
