Answer:
See the anwers below
Explanation:
To solve this problem we must understand that the weight of anybody is defined as the product of mass by gravitational acceleration. Gravitational acceleration depends on the place in space where a certain body is located.
where:
W = weight [N]
m = mass = 100 [g] = 0.1 [kg]
g = gravity acceleration [m/s²] or [N/kg]

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
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.
