A scientist is wondering why a certain region in the ocean doesn't have maximum phytoplankton growth, despite having plenty of nutrients. The scientist samples the water for nutrient levels and finds that there is 2.5 ug/L of Phosphorus and 27ug/L of Nitrogen. What can be said about the water?
A) The water is nitrogen limited
B) The water is phosphorus limited
C) The water has an adequate nitrogen and phosphorus, so it is likely iron limited
D) The water has adequate nutrients, but is likely limited by light availability

C The water had adequate nitrogen and phosphorus, so it is likely iron limited.

Explanation:

Phytoplankton are single- cell organisms that live in oceans.

They require nitrogen, phosphorus and trace amount of iron to survive.

From the scientist's results after testing the water for nitrogen and phosphorus,there are reasonable amount of these elements.

Therefore insufficient iron in the water is the reason why he could find plenty phytoplankton in the ocean.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
