d. C – 12

Answer 1

1. A 2. C 3. A 4. B 5. D

Answer 2

1. C Vegetation

2. D Geiger Counter

3. A True

4. B False

Step-by-step explanation:

1. Rock color, Radioactivity and magnetism are important characteristics to determine the kind of mineralization and if it is economically viable.

2. Geiger Counter is a device that is used to detects alpha, beta or gamma rays through ionization of the radiation

3. 2H2 + O2 = 2H2O + Energy

4. Carbon-12 is an isotope of carbon, carbon-13 and carbon-14 are also the isotopes of carbon
