Which of the following is an application of the principle of constant proportions? a) Siliceous ooze accumulates on the ocean floor as it is being dissolved because it accumulates siliceous tests faster than seawater can dissolve them. b) Calcium carbonate dissolves at an increasing rate with increasing depth until the calcite compensation depth is reached. c) The concentration of a single major constituent can be measured to determine the total salinity of a water sample. d) Increasing pressure increases the number of water molecules in a given volume and inhibits the number of ice crystals.

c) The concentration of a single major constituent can be measured to determine the total salinity of a water sample.

Explanation: The law of constant proportions is also known as Proust’s law or as the law of definite proportions. It states that chemical compounds are consists of elements that are present in a fixed ratio by mass.

No matter how much the salinity increases or decreases in the ocean, the number of ions proportional to each other remains constant.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
