100
The positively charged particle in the nucleus
What is a proton?
100
When the particles of a substance are closely packed together have very little energy
What is a solid?
100
When a solid warms up and becomes a liquid
What is melting?
100
The molecules that are at the beginning of an equation
What are the reactants?
100
These have a pH of 1-6 and turn yellow, orange, or red
What are acids?
200
The particle in the nucleus that doesn't have a charge
What is a neutron?
200
When the particles of a substance are very far apart and moving fast, having a lot of energy
What is a gas?
200
When a gas cools and becomes a liquid
What is condensation?
200
The molecules that have been rearranged because they have gone through a chemical reaction
What are the products?
200
These have a pH of 7, and living things are mostly made of these
What are neutrals?
300
The negatively charged particle in the outer energy rings of an atom
What is an electron?
300
The stuff that everything in the universe is made of
What is matter?
300
When a liquid cools and becomes a solid
What is freezing?
300
Energy cannot be created or destroyed, it simply changes form
What is the Law of Conservation of Mass?
300
These have a pH of 8-14 and turn blue or purple
What are bases?
400
They make up the mass of an atom
What are protons and neutrons?
400
The particles of a substance are sort of close to one another, they have a definate volume but no definate shape
What is a liquid?
400
When a liquid warms up and becomes a gas
What is evaporation?
400
The big number that tells you how many molecules are present
What is the coefficient?
400
This is something that is added to make a chemical reaction take place faster
What is a catalyst?
500
When there are more protons or electrons in an atom
What is an ion?
500
The amount of matter something is made of
What is mass?
500
When a solid heats so rapidly that it becomes a gas
What is sublimation?
500
The little number that tells how many atoms in the molecule
What is a subscript?
500
When you add more acid to a base or more base to an acid
What is neutralize?
