Answer: A=12
Explanation:
4.5
The amount of chemical remaining after twelve seconds in the first reaction is:
A = 12 - 0.5(12)
= 12 - (6)
= 6
In the dissolved reaction, the amount of chemical loses half of itself every four seconds. This is the same thing as dividing by 2 every four seconds.
This is an exponential decay, so the amount of chemical divides by 4 every eight seconds, and by 8 seconds every twelve seconds. The amount remaining after twelve seconds in the second reaction is:
A' = 12/8
= 3/2
= 1.5
The difference between the amounts of chemical remaining is:
6 - 1.5 = 4.5
Therefore, A is 4.5 g greater than A' after twelve seconds.
Newton’s first law of motion states that ever object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force is the definition of Newton’s first law of motion
I believe the answer to this is Genetic Diversity.
