molar mass
To find this, add masses of all elements in a compound together.
least
If pressure is increased to a gaseous reaction at equilibrium, the reaction will shift toward the side with the _________ amount of moles.
compressible
Gases are easily ____________ & expand to fill their container.
unsaturated
A(n) ____________ solution can hold more solute.
increased
Increased temperature = ___________ solubility for solids
pressure
In a gas, this is caused by the force of gas particles colliding with their container walls.
neutrons
neutral charge, found in nucleus
protons
positive charge, found in nucleus
isotope
Same element, different number of neutrons
cross method
This is how you identify the number of ions that will participate in an ionic bond.
mass number
