Answer:
hydrogen
Explanation:
pH is a measure of the ion concentration of hydrogen in a solution.
In chemistry, it literally means power of hydrogen ions and it is a measure of the molar concentration of hydrogen ions in a particular solution, thus specifying the acidity, neutrality or basicity of chemical solutions.
Mathematically, the pH of a solution is given by ![pH = -log 10[H^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%2010%5BH%5E%7B%2B%7D%5D)
Hence, a solution with a pH of 7 is neutral.
Also, a solution with a pH below 7 is acidic but basic if it's pH is above 7.
A hypothesis is a proposed explanation made on the basis of limited information while a theory is a series of ideas intended to explain something.
It would be A. Because think of the explanations Jasons friend could say to them that would be a negative 'statement'.
It uses microwaves as little heatwaves and uses them to heat the food
