Half life is the time taken for a radioactive isotope to decay by half its original mass. In this case the half life of carbon-14 is 5.730 years.
Using the formula;
New mass = original mass × (1/2)^n; where n is the number of half lives (in this case n=1 )
New mass = 2 g × (1/2)^1
= 1 g
Therefore; the mass of carbon-14 that remains will be 1 g
Answer:
C. Magnetization of iron
Explanation:
This is a chemical change and cannot be undone by physical means therefore it isn't a physical change
Answer:
56 is the mass
Explanation:
You would add 26 and 30(the protons and neutrons). I didn't add the electrons because they are so small their mass is negligible in this situation.
Inference is an educated guess darlin
The nucleus in the atoms if gold deflected the alpha particles.
