A= 16.5x100=1650
b=120 divided by 100= 1.2lb
that’s all I know.
Answer:
Explanation:
= Half-life of carbon = 5700 years
t = Time at which the remaining mass is to be found = 10400 years
= Initial mass of carbon = 11 g
Decay constant is given by

Amount of mass remaining is given by

The amount of the substance that remains after 10400 years is
.
Answer:
it is b just trust me man I know
Reactant + reactant = product
C + O2 = CO2

Explanation:
The compound is acetylacetone. This compound is immiscible with water because it is completely nonpolar.
