After 17190 years, Carbon-14 will reach a mass of 15 grams.
Pi is your initial amount (120 grams)
0.5 as your exponential base represents your HALF life hence 0.5
t represents the time elapsed
c represents your given half life value of (5730)
P(t) represents the exponential function of your half life
120/2 =60
60/2 = 30
30 /2 = 15
As you can see above, 3 half lives of 5730 years EACH degraded the carbon-14 to 15 grams. You divide each number by two as it is a HALF life.
P(t)= Pi (0.5) ^t/c
P(17190) = 120 (0.5) ^17190/5730
P(17190) = 120 (0.5) ^3
P(17190) = 15 grams
So your answers should be 3 half lives or after 17190 years have elapsed!
NH4Cl + heat forms NH4 + + Cl-
The answer is metamorphism
Ionization refers to the process of losing or gaining electrons. The correct answer is D.
