Answer:
a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Explanation:
simpler definition: It's just a thing that you're willing to define before your experiment begins. You're predicting what'll happen, or what you'll earn through your experiment.
Let's say that you're doing an experiment based on using fertilizer on your plant. Your hypothesis can end up like this, "If I add fertilizer to my garden, then my plants will grow faster."
Please correct me if I'm wrong.
In the titration of acetic acid with a strong base NaOH, the concentration of acetic acid is determined using the volume and molar concentration of NaOH used for titrating the vinegar solution. NaOH and acetic acid react in 1:1 mole ratio.
![CH_{3}COOH(aq) + NaOH(aq)-->CH_{3}COONa(aq)+H_{2}O(l)](https://tex.z-dn.net/?f=CH_%7B3%7DCOOH%28aq%29%20%2B%20NaOH%28aq%29--%3ECH_%7B3%7DCOONa%28aq%29%2BH_%7B2%7DO%28l%29)
When a drop of the strong base, dispensed from the buret sticks to the walls of the Erlenmeyer flask but is not washed into the flask containing vinegar, it means that the recorded value of NaOH dispensed will be higher than the actual value required for the titration. So, the reported moles of acetic acid calculated from the moles of NaOH used for the titration will be higher. So, the mass percent reported will be higher than the actual value.

The process in the nitrogen cycle converts nitrogen into its most polluting form will be "nitrification".
The biological process of nitrification turns ammonia into nitrite and nitrite into nitrate. The technique of denitrification, which turns nitrate into nitrogen gas, is such treatment option if requirements demand that the resultant nitrate be eliminated.
A surplus of nitrogen compounds could result in pollutants like ammonia and ozone that can affect plant growth, visibility, and human capacity to breathe. Excess nitrogen from the atmosphere that returns to earth could be damaging to the health of forests, soils, including streams.
Therefore, the process in the nitrogen cycle converts nitrogen into its most polluting form will be "nitrification".
