you cant ask for test answers on brainly. use quizlet or something else if you want !
Explanation:
8.43 x 10^-6. Move the decimal back six places to make a 3 digit number and it going right means a negative number.
Answer:
50 atoms have decayed during that time
Explanation:
The radioactive decay is represented as

Where N is the amount of radioactive element after a certain time period
N0 is the amount of radioactive element during the initial time period
X is the half life of the radioactive element
Substituting the given values in above equation, we get:
atoms
So, 50 atoms of carbon-14 remain are left after decaying for 5700 years.
Hence, atoms of carbon-14 that decay during 5700 years are 100-50 - 50
