A scientist is wondering why a certain region in the ocean doesn't have maximum phytoplankton growth, despite having plenty of n
Advocard [28]

Answer:

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.

5. In a general chemistry laboratory experiment, a student produces 2.73 g of a compound. She calculates the
OLEGan [10]

The percent yield is given by the actual and the theoretical yield. The percent yield of the 2.73 gm compound is 80.3%. Thus, option b is correct.

<h3>What is the percent yield?</h3>

The percent yield is the ratio of the actual yield to the theoretical yield. It is calculated as:

% Yield = Actual yield ÷ Theoretical yield × 100%

= 2.73 ÷ 3.84 × 100%

= 71.09 %

As the closest number to 71.09 is 80.3% the percent yield will be 80.3%.

There is no limiting reagent in the reaction between the copper iodide and mercury iodide as the moles of the reactants and the products are in equal quantity.

Hence, option b. there is no limiting reagent in this reaction.
