An igneous rock that you are analyzing contains the mineral zircon. The zircon was processed to acquire a precise measurement of the Parent and Daughter atoms locked within that mineral. You discover that there is a ratio of 15 Lead 207 atoms (207Pb) to 0.0667 Uranium 235 atoms (235U). How many half-lifes passed since that mineral formed? What is the age of the rock based on it's half-life? A. 4 Half-lifes/2.8 billion years old

B. 3 Half-lifes/2816 trillion years old

C. 3 Half-lifes/2816 billion years old

D. 2 Half-lifes/2.8 billion years old

E. 4 Half-lifes/2.8 million years old

F. 2 Half-lifes/2.8 million years old

it is a good conductor

explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
