100
Slicing cake.
What is a physical change?
100
Subatomic particle, inside the nucleus, mass of 1 amu, and has a positive charge.
What is a proton?
100
Occurs when atoms "share electrons". Usually occurs between two nonmetals.
What is a covalent bond?
100
The total number of protons and neutrons in an atom's nucleus.
What is the mass number?
100
All substances on the left side of the equation.
What are reactants?
200
Burning gasoline.
What is chemical change?
200
Subatomic mass, found outside the nucleus, has a negative charge.
What is an electron?
200
Occurs when an electron is transferred completely. Usually occurs between a metal and a nonmetal.
What is an ionic bond?
200
The mass number of an atoms that has 7 protons and 7 neutrons.
What is 14?
200
All substances on the right side of the equation.
What are products?
300
Melting sugar.
What is physical change?
300
Makes up most of the mass of the atom.
What is the nucleus?
300
Particles that become charged as a result of losing or gaining an electron.
What is an ion?
300
The number of neutrons in an atom if the atomic number is 6 and the mass number is 14.
What is 8?
300
Number placed in front of a compound formula to balance an equation. It changes the number of moles/molecules without changing the formula.
What is a coefficient?
400
Dissolving salt in water.
What is physical change?
400
Determines the identity of the atom.
What is number of protons?
400
Formed as a result of an electron being transferred.
What is ionic compound?
400
The molar mass of water.
What is 16 g/mole?
400
Atoms do this during a chemical reaction.
What is rearrange?
500
Photosynthesis.
What is a chemical change?
500
Only function is the make the atom heavier. The number of these can vary.
What is a neutron?
500
An attractive force between atoms.
What is a bond?
500
The molecular mass of water?
What is 16 amu?
500
Happens to matter in a reaction instead of being created or detroyed.
What is conserved?
