7 chemical reactions you can't miss

It's no use, you've already decreed your deadly hatred of chemistry and think none of that makes sense except when you watch "The Big Bang Theory, " but this feeling that maybe science isn't such an absurd thing lasts no more than one episode. . Alright, we understand.

Every time your teacher came up with some new chemical reaction you got a stomachache and wondered how it could change your life and why you should learn all that? It is completely human to ask this kind of question, but before you think that this text will bring answers to your most complex questions, we have already advanced: it will not.

What may be clearer to you here now is how, in fact, some of those chemical reactions that have plagued your adolescence do happen - and perhaps that may spark your interest in studying more about it.

1 - Hydrophobic Tennis

This type of material simply repels water (and most liquids) that may come into contact with it. In this case, Nanotechnology, which works with the manipulation of substances to make them “perfect” for certain applications, comes into play.

2 - Magic!

To do this experience at home, you will need: water, colorless vinegar, 10-volume hydrogen peroxide, and a potassium permanganate tablet. If you want to do this, watch the video below. The difference from GIF to video is that the process is reversed: whereas in GIF the substance is poured - probably - into a hydrogen peroxide solution; In the video, hydrogen peroxide is poured into the solution with the permanganate.

3 - Explosion of a hydrogen balloon

Despite being the most common substance in the universe, hydrogen alone, in gas form, is extremely flammable, especially when it comes in contact with air. The result of this combustion, however, is water, so this gas would be ideal as a source of energy - but this is still under study, as the production of this gas is a rather complicated process.

4 - Carbon Fiber Film

Carbon film is a polymer reinforced with extremely strong but lightweight hydrophobic fibers that react like glue when other material is added to water.

5 - Satan, is that you?

Apparently mixing NH4Cr2O7 and HgSCNs produces nothing. Unless you set the mix on fire. In this case, tentacle-shaped ashes may be observed. Witchcraft?

6 - Hydrophobic Sand

You already know that hydrophobic materials repel water, such as this sand, which remains dry even after contact with the liquid.

7 - Light

I bet you didn't know it was possible to do that. To better understand this process, watch the video below:
