Answer: Salt

Explanation: Salination can be defined as the increase in the salt concentration in the soil. Eventually it becomes toxic to the plants when it reaches the concentration of 3,000 - 6,000 ppm.

It decreases the osmotic potential of soil as a result of this plants cannot get water from the soil.

The salt in the soil comes from the irrigation as the water which is used to irrigate the field contains salts in it. As the water evaporates the concentration of salt in the soil increases.

The half — life of nickel is 96 years. How much of a 30-gram sample is left after 270 years?
-Dominant- [34]

The amount of the 30 gram-sample that will remain after 270 years is 6.61 grams

<h3>How to determine the number of half-lives </h3>

We'll begin by obtaining the number of half lives that has elapsed. This can be obtained as follow:

  • Half-life (t½) = 96 years
  • Time (t) = 270 years
  • Number of half-lives (n) =?

n = t / t½

n = 270 / 99

n = 2.8125

<h3>How to determine the amount remaining </h3>
  • Original amount (N₀) = 30 grams
  • Number of half-lives (n) = 2.8125
  • Amount remaining (N) =?

The amount remaing can be obtained as follow:

N = N₀ / 2^n

N = 30 / 2^2.8125

N = 6.61 grams
