These are three variables that affect gases.
What are temperature, pressure, and volume? (Also, # of moles/particles)
This is the formula for potassium sulfide.
What is K2S?
When radioactive materials have a number of protons greater than 83, they undergo this type of decay.
What is alpha decay?
The number of significant figures in 2.30 x 105?
What is 3?
This group of cations will lose 1 electron.
What is Group 1A, alkali metals?
This is what happens to volume, at constant temperature, when pressure increases.
This is the formula for carbon tetrachloride.
What is CCl4?
When a radioactive element has too many neutrons, it will undergo this type of decay?
What is beta decay?
This element is in group 2A, period 5.
What is strontium?
This name for the law that shows the relationship between temperature and volume.
