The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7
<h3>What is
pOH scale?</h3>
Based on the relative concentration of hydrogen and hydroxyl ions, the pH and pOH scales are used primarily in chemistry, biology, and soil science to describe and measure the acidity and basicity of neutral, acidic, and basic solutions in water.
The terms pH and pOH scale are frequently used and crucial for determining the chemical, biological, and soil health by converting the values of hydrogen or hydroxyl ion concentrations or by utilizing pH paper and meters.
The pH scale or chart, which measures the concentration of hydrogen and hydroxyl ions in acidic and alkaline solutions, was initially developed by Sorensen.

It is the independent variable because you can ‘manipulate’ or ‘change’ it.
Answer:
Protons and neutrons which packed tightly into central core of the atom.
Explanation:
Atoms are composed of three subatomic particle; electron, proton and neutron. Electrons are negatively charged, protons are positively charged whereas neutrons are neutral, hence does not have any charge.
Out of three, protons and neutrons are present in the nucleus of the atom.
Nucleus is the central part of the atom possessing most of the mass of the atom. In the nucleus, protons and neutrons are tightly packed with the help of nuclear force.
Electrons are present around the nucleus also called electron cloud.
Therefore, nucleus are composed of protons and neutrons which packed tightly into central core of the atom
I think the answer is 98 grams
Answer:
The gas pressure in both mmHg and torr is 1.00 x10⁻⁴.
Explanation:
The standard atmosphere (1 atm) equals a pressure of 760 mmHg, where mmHg represents the pressure exerted by a column of mercury 1 mm high. <u>The mmHg unit is also called the torr</u>, after the Italian scientist Evangelista Torricelli, who invented the barometer. Thus,
1 torr = 1 mmHg
and
1 atm = 760 mmHg = 760 torr
Therefore, we do the following conversion:
1 atm ------------------- 760 mmHg
1.32x10⁻⁷ atm ------- x= 1.00 x10⁻⁴ mmHg (3 significant digits)
