Answer:

Hydrogen Peroxide is known as a dental “debriding agent”. But when used on skin for minor wounds it will foam and turn surrounding tissue white. ... H2O2 decomposes easily to make water (H2O) and a single free oxygen atom which is looking for something to react with - like your skin.

Aspartame, phenylalanine, and aspartic acid were examined by thin‑layer chromatography (TLC) using ninhydrin as the visualizatio

Marizza181 [45]

Answer:

Explanation:

The following precautions should be followed for a safe and efficient laboratory environment:

The TLC plate should be laid on a paper towel, to ease picking it from the bench top.

The used TLC spotters and the used TLC plates in the appropriate waste containers provided for this purpose should be placed in the blood.

Spills should be cleaned up and contaminated surfaces should be washed with water.

The pipette and/or glassware should be rinsed again with the distilled water, in case there is the slightest doubt about the contamination.

Everything used should be washed with distilled water, including the pipettes.

how does the main function of the nervous system help the body react to internal and external stimuli??

Irina-Kira [14]

Nerves send signals to your brain from your spinal cord. If something is burning your nerves will send a pain signal from the area of the burn to your brain through you spinal cord. Then your brain sends a signal back to the nerves that there is pain and you should avoid it. Same with internal nerves and same with touch.

What is the volume of 1.50 lb (pounds) of mercury? The density of mercury is 13.546 g/mL. Use the conversion that 1 kg = 2.20 lb

Arada [10]

Answer:

50.3mL of mercury are in 1.50lb

Explanation:

Punds are an unit of mass. To convert mass to volume we must use density (13.546g/mL). Now, As you can see, density is in grams but the mass of mercury is in pounds. That means we need first, to convert pounds to grams to use density and obtain volume of mercury.

Mass mercury in grams:

1.50lb * (1kg / 2.20lb) = 0.682kg = 682g of mercury.

Volume of mercury:

682g Mercury * (1mL / 13.546g) =

<h3>50.3mL of mercury are in 1.50lb</h3>

The student is now told that the four solids, in no particular order, are aluminum chloride (AlCl3), sugar (C6H12O6), benzoic ac

zaharov [31]

Answer:

AlCl₃, NaBr, C₆H₅COOH, C₆H₁₂O₆.

Explanation:

The more ions in solution, the greater the conductivity of a solution because these charged particles can carry electrons in the solution.

In the first place, when AlCl₃ dissolves in water it produces 4 ions:

AlCl₃(aq) ⇄ Al³⁺(aq) + 3 Cl⁻(aq)

If the solution is 0.20M in AlCl₃, it will be 4 x 0.20M = 0.80M in ions.

Secondly, NaBr is a strong electrolyte (complete ionization) so it produces 2 moles of ions per each mole of NaBr dissolved:

NaBr(aq) ⇄ Na⁺(aq) + Br⁻(aq)

If the solution is 0.20M in NaBr, it will be 2 x 0.20M = 0.40M in ions.

Then, benzoic acid is a weak electrolyte (partial ionization) so it will produce less than 2 moles of ions per each mole of benzoic acid dissolved:

C₆H₅COOH(aq) ⇄ C₆H₅COO⁻(aq) + H⁺(aq)

If the solution is 0.20M in benzoic acid, the solution will be far below 0.40M in ions.

Finally, sugar has only nonpolar covalent bonds so it will produce no ions in solution, thus being a poor electricity conductor.
