The amount of time it takes for 1/2 of it to decay or dissapear
this is liike compound interest because it takes the same amount of time to decay 1/2 of it, regardless of the amount
example
lets say half life of element x is 1 year
if yo has 32 grams, after 1 year, it decays to 16g
2 years decays to 8
3 years decays to 4
4 years decays to 2
5 years decays to 1
etc
hope this helps (I'm not the best at chem)

copper (II) sulfate pentahydrate
==>

Glucose is the starting molecule for glycolysis.
D. Wind will always move from areas of high pressure to low pressure. It's the reason we have weather, or one of them. Temperature is another factor.
B. That is the definition of the greenhouse effect.
The answer is B. The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume.
