Answer:
1520 mmHg
Explanation:
Let's solve this by a factor conversion:
1 atm → 760 mmHg
2 atm . 760 mmHg / 1 atm = 1520 mmHg
Thin layer chromatography(TLC) works with the principle of separation through adsorption.
It is used in the isolation and extraction of lipids through the following steps:
- apply the lipid samples spots in the bottom of the plate.
- also apply sample solution to the marked spot
- pour the mobile phase into the TLC chamber and use a moist filter paper to cover it. this is done to maintain equal humidity.
- then place the plate in the TLC chamber and close it with a lid.
- the plate is immersed into the solvent (mobile phase) for its development. this is done, keeping in mind that the sample spot should be above the solvent.
- once the sample spots are developed, they are removed and dried.
- this is later viewed using the UV light chamber to see the isolation of the lipid sample.

So basing on my understanding of this so far, an atom is an element that has the same number of protons and neutrons, an ion is an element that has different numbers of protons and electrons, an ion is positive when it has more protons than electrons and negative when it has more electrons than ions .
The statement that best represents the law of conservation of matter with regard to chemical reactions would be the one that says the <u>reactants and products have the same number and type of atoms, but the atoms may be recombined.</u>
First, it is important to know that chemical reactions involve the breaking of bonds between atoms in reactants and the recombination of the atoms in products.
The law of conservation of matter also states that matter (atom) can neither be created nor destroyed in a reaction, but can be converted from one form to another.
Thus, going by the above points, the number of atoms of each element in reactants must also be the same in products. However, recombination of the atoms would most likely have occurred before reactions can take place.
