salt is completely soluble in water. Na+ will be surrounded by OH- and Cl- will be surrounded by H+
Answer: Option E, in 12 years.
Explanation:
A geometric growth model is characterized by its finite growth rate, known as lambda. The size of the population after a unit of time has passed can be calculated using the last known size and lamba as:

Starting from the initial value of population, the next one will be calculated multiplying by 1.4, and the next one multiplying again by 1.4, thus we can define a function that relates the time passed in year to the size of the population:

Substituting our values we get the function that defines the growth of our poupulation:

Then, we just have to clear the t that gives a population of 500:

Thus, at 12 years, the population will be greater than 500.
Answer:
False
Explanation:
The world changes at different times, much like how people mature at different times. If the world was changing all the same speed, we would've had a mass continent again.
