If there are no chemical controls which can be implemented at your worksite than one should wear recommended PPE for protection .
- PPE means personal protective equipment .
- PPE at the worksite is selected to reduce the risk to health and safety .
- PPE includes aprons , overalls , gloves , footwear face shields , chemical resistant glasses , and respirators .
- The PPE and administrative control measures depends upon the behavior and supervision of human .
- The efficacy of PPE depends entirely on the workers following the procedures and instructions appropriately .

I believe it forms an anion that has a larger radius.
Well, it has 10 protons.
For, a atom in its neutral state has the same number of protons as electrons. Thatswhy, it has a neutral charge. The protons have a positive charge (1+); the elctrons have a negative charge(1-). So, the charges cancel out. Like, a atom has 11 electrons and 11 protons. See-
11 e- = -11
11 p+ = +11
Then,
. So, no charge. Its neutral. It happens in case of every atom.
And, if an atom has (2-) charge that means it has two extra electrons. Two more electron than the number of protons. It once had the same
number of protons and electrons. Then two more electrons give it a (2-) charge.
Thatswhy, if we subtract 2 from 12, we can get the number of protons.We can calculate the number of protons as,
Okay, what's the proof? Want it?
We know there are 10 protons and 12 electrons. Let's see it.
Eureka! That's it. I got it. It's right.
AND ANOTHER QUESTION ARISES,
If all atoms have the same number of protons and electrons then, when does the number of electron decrease or increase? How do the atoms come to have positive or negative charge?
Well, this happens because of ionic bonding. I can't explain all these stuff, right here. To obtain more information on bonding, search it on GOOGLE.
The answer is
kangaroo rat is adapted to living in an environment where water is scarce.
The answer is: molecular polarity.
Paper chromatography is an analytical method used to separate colored substances.
Substances are distributed between a stationary phase and a mobile phase.
Substances have different chemical structures and because of that, the different polarity, so each molecule have a different solubility in the solvent.
If a substance is very nonpolar, it will not dissolve at all in a very polar solvent.
If water (polar substance) is a solvent, the more polar the color, the higher it will rise on the papers.
