Answer:

The correct answer is option a, that is, phosphates.

Explanation:

One of the extreme environmental issues, as it leads to deterioration of water quality, is eutrophication. It is one of the prime obstructions in attaining the quality objectives set up by the Water Framework Directive. All the water bodies’ results in a slow and natural process of eutrophication, however, the process has gone through brisk progressions due to many human activities. The excess use of phosphates in the form of fertilizers is one of the prime reasons for eutrophication.

How many grams are in 11.9 moles of chromirum
faust18 [17]

Answer:

Explanation:

Method 1 proportion

1 mole of chromium is 52 grams

11.9 moles = x grams

1/11.9 = 52/x                    Cross multiply

x = 11.9 * 52

x = 618.8                         grams

Now I have used an approximate mass for Chromium. The answer you get here is expected to reflect the weigth given on your periodic table Use that to get your answer. You should give a number very close to mine. Round to 3 places as in 619.

Method Two  Formula

mols = given mass / molecular mass

11.9 = given mass /  51.9961          Multiply both sides by  51.9961

11.9 *51.9961  = given mass            

given mass = 618.75

given mass = 619
