Which makes the phosphorus cycle different from the carbon cycles
azamat
<span>The phosphorus cycle is different compared to the water,carbon, and nitrogen cycle because it can not be found in the gas state. Phosphorus is only found in land, water, and sediment. The phosphorus cycle is a bio-geochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. The other cycles is the process by which it is converted between its various chemical form. Phosphorus has small particles that only sometime go up into the atmosphere and contribute to acid rain but other than that phosphorus stays in and on land, sea, and sediment.(:
Good luck!</span>

How much did one drop of HNO3 cause the pH of water to change?
ankoles [38]
Assuming that there is missing information in this question I’m just going to go ahead and say that it’s lower.

HNO3 (nitric acid) is a very strong acid which should be found on the lower end of the pH scale. While water, on the other hand, is neutral and found at a pH of 7.

So if you add one drop of a strong acid into a neutral solution of 100ml let’s say, one can assume that the pH of that solution is now very low and probably found between 1-3 on a pH scale.

Reminder:

-Acids are found between 1-6 on the pH scale. The lower the number the stronger the acid

-Bases are found between 8-14 on the pH scale. The higher the number the stronger the base
