The pH value can be measured using electrochemical measuring systems, litmus paper, or indicators and colorimeters. The easiest way to take a pH measurement is to use litmus paper or a colorimeter. The advantage of this type of pH measurement is that the pH range is well known and they are easy to apply.
<span>The pH scale is a logarithmic scale. Each change of 1 unit in pH represents a 10-fold change in hydrogen ion concentration. As the pH gets smaller the hydrogen ion concentration gets larger. Since you have gone from pH 5 to pH 3 there is a 100-fold increase in [H+].
For pH = 5; [H+] = antilog 10^-pH = 1.0 x 10^-5 M
For pH = 3; [H+] = antilog 10^-pH = 1.0 x 10^-3 M
(1.0 x 10^-3)/(1.0 x 10^-5) = 1.0 x 10^2 hope this helps</span>
Answer: The answer is Parasite ma dude
Explanation:
In evolutionary ecology, parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life.

Answer:
The electron-domain geometry is linear. The molecular geometry is linear.
Explanation:
According to the valence shell electron pair repulsion theory (VSEPR), the shape of a molecule depends on the arrangement of electron pairs present on the valence shell of the central atom of the molecule. Electron pairs are arranged in such a way as to minimize repulsion between them. The electron pairs are positioned as far apart in space as possible.
In CS2, both the molecular and electron pair geometries are linear because the electron pairs and bonding groups are positioned at an angle of 180° from each other. Hence the answer.
