I know nothing at all about tanning. I want to know if there are any chemcials used in the tanning industries that's innocuous inherently, but may be dangerous in large quantities? (In leather tanneries)

For instnace, sleeping pills may be inerently harmless, but they're harmful if you take the entire bottle. Something on those lines?

Help, somebody!

Hi... Im using a deodorant that has the following ingredients:

Material/Ingredients: Alcohol Denat, Water (Aqua), Fragrance (Parfum), PEG-40 Hydrogenate Castor Oil, Acrylates/Octylacrylamide Copolymer, Limonene, Linalool, Ethylhexyl Methoxycinnamate, Benzyl Salicylate, Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde, Benzophenone-3, Butylphenyl Methylpropional Hydrolyzed Jojoba Esters, Dodium Carbonate, Alpha-Isomethyl Ionone, Coumarin, Citral, Hydroxycitronellal, Eugenol, Geraniol, BHT, D&C Red No.33 (CI 17200), FD&C Yellow No.5 (CI 19140), FD&C Blue No.1 (CI 42090), EXT.D&C Violet No.2 (CI 60730)

I was wondering if any are antiperspirants? If so I will stop using it as I've heard it's really bad for you to actually stop your body from sweating and that it may be a cause for cancer.

Thanks!

I understand there is a process that separates the salt from the solution of salt and water and leaves just the 'rare earth minerals'. (These rare earth salts are meant to be beneficial when consumed)??

I don't understand how to do this ...

The elements calcium, barium strontium, zinc, cadmium, and others combine with oxygen in the same ratio as magnesium. Write out the balanced equation for the reaction of these elements with oxygen.

I would be so grateful if anyone could help.

Two crystalline forms of white phosphorus are known. Both forms contain P4 molecules, but the molecules are packed together in different ways. The alpha form is always obtained when the liquid freezes. However, below -76.9 °C, the alpha form spontaneously converts to the beta form.

P4(s, alpha) -> P4(s, beta)


Indicate which of the following statements are true or false, with regard to the above process.


a. Below -76.9°C, the sign of ΔG for this process is negative.
b. The alpha phase has the more ordered crystalline structure.
c. At -76.9°C, the two solid phases cannot coexist.
d. The sign of ΔH for this process is negative.
e. At -76.9°C, ΔG for this process is less than zero.
f. The sign of ΔS for this process is positive.
