I just learned about “Salt (NaCl) is actually a combination of a highly poisonous gas (Cl) and a hazardous metal (Na)”.

I’m sure there are lots of examples in life that this rule also applies to.

    O2 is great! Vital, even! Unpaired oxygen is highly toxic to all forms of life

      O3 is again not good for us. Not breathe it and die but it attacks your lungs if you inhale too much.

          O3 (Ozone) is effectively airborne bleach. The molecule is ‘happy’ to dump an oxygen and become O2, the last O needs something to bind to however. Large, complex hydrocarbons are particularly vulnerable to damage from this. Unfortunately, our bodies are basically made of complex hydrocarbon chains. While our skin is quite resistant to damage (we have an ablative layer of dead skin cells), our lungs and eyes aren’t. Ozone will do significant damage, in even small doses.

          Luckily, the same thing that makes it dangerous also makes it unstable. O3 breaks down to O2 relatively quickly (20 minute half-life, I think). It’s also amazing at decontaminating and deodorising a room or building. Bacteria, viruses and VOCs(volatile organic molecules, aka smelly stuff) are particularly vulnerable to damage from O3. You just have to remove anything you don’t want to damage (like houseplants, pets, or children), and keep the place relatively sealed to not pollute the area too much.

            There’s also something deeply unsettling about the smell of O3 in any concentration where you can truly smell it, not like getting punched in the lungs that ammonia bicarbonate is, and less irritating than than NOx compounds, but the almost sweet and sickly pleasant smell to it carries a sense of dread.

            Speaking of which NOx is another good one; N2 is (essentially) inert and makes up most of our atmosphere, O2 has already been explained, but run a high frequency (white) electric arc in our atmosphere and you cause the N2 and O2 to combine in varying quantities producing NOx compounds.

            NOx compounds are effectively gaseous nitric acid, it has a brown/red colour, and on constant with water it forms nitric acid. It doesn’t matter whether that water is in a beaker with the NOx being bubbled through it, or the water that exists in your sinuses, lungs and eyes.

            You lose your sense of smell pretty quickly when exposed to it and concentrations can build up quicker than you expected, if you’ve been overexposed to it, you’ll wake up the next day or even a few hours later, feeling like you’ve got the worst sore throat in your life, like someone stamped on your throat then tried to scrape it clean… assuming you do wake up.

            1/10 do not recommend.

            This high propensity for reaction is also why we got a massive hole in the ozone layer. Aerosols and hydrocarbons got dumped into the atmosphere, causing a massive portion of our ozone to split into O2 and free O due to higher exposure to UV radiation. All of that newly freed singular oxygen then started binding with the hydrocarbons in the upper atmosphere instead of reforming into ozone, heavily depleting it over time

          It’s reactive and creates free oxygen radicals that will attack nearly anything, so it’ll actively oxidize your lungs.

          Not sure anymore. The lesson we were taught just basically said that it damages your lunge if you breath in too much. There were some other interesting thins in that lesson. Basically that cars release not only co2 but also pure c into the air which binds o3 elements into co2 and o2. Which is why in cities and region with more traffic less o3 can be found. O3 is also more common and really sunny days. But please take this with a grain of doubt as this was some years ago.

            O3 is an unstable molecule that acts effectively like bleach, it forces an Oxygen atom/ion onto another molecule. This tends to do significant damage to large hydrocarbons, like those making up our bodies and the cells’ internal machinery.

            It’s produced naturally by sunlight hitting oxygen molecules in the atmosphere, and by lightning. It’s also a byproduct of a number of processes, like some combustion engine designs. It then breaks down quite quickly into normal oxygen, either by reacting with something else, or by combining with a 2nd O3 (2O3 ==> 3O2). This has a short half life of around 20 minutes.

      Nice distraction with the O2 factoid. We have our own instance… if you’re interested.

      Obligatory j/k because it would not surprise me if that was a thing.

      Jesus. Not even alongside. It is poisonous to consume alcohol up to three days after eating them.

      The symptoms can occur if even a small amount of alcohol is consumed up to three days after eating the mushrooms, although they are milder as more time passes.

    Grapefruit fucks with a lot of medications (if you regularly eat grapefruit, check to make sure none of your medications are affected by it). The effects can range from nullifying the medication, to increasing the effects (potentially fatally), or causing the medication to become toxic (also potentially fatally).

    Wrinkly, wet fingers (after a nice long shower) grabbing soft, dry, fluffy blankets. Eeeeuuuuggggghhhhjjjjj. God, it hurts just thinking about it.

    I don’t like espresso, or any coffee really, and I definitely don’t like Liquor 43. But there’s a South American cocktail called a Carajillo that’s those two ingredients, fresh espresso and Liquor 43 and nothing else, dry shaken together… and its friggen delicious. Just absolutely amazing.

      Hehe, not just South American, it’s pretty common in Spain, with a variety of spirits … I’ve seen people using Cognac, Anise … all kinds really, some more controversial than others.

    The gases of Hydrochloric Acid and Ammonia mixed together form Ammonium chloride. Which, among other things, is used as salmiak to make salty licorice.
    I remember making this in high school, it’s the very first thing that pops in my head whenever I think of bad + bad = good. Granted, you must like salty licorice, or it’ll be bad + bad = disgusting :)

    Chlorox and ammonia are effective cleaners on their own and life threatening if mixed.

    Sugar and acidity go together well but can be unpalatable on their own at the levels that theyre used. i.e 45 grams sugar / can would gag you without that acidity. the acidity on its own would not taste great.

    Some spices synergize with other spices but arent great by themselves.

    fat by itself: gag, bread by itself: boring, bread + fat: tasty

    Carbon Dioxide is poisonous by itself but in small amounts it can stimulate breathing. Pure Oxygen can cause nerve damage over long periods of time but is necessary for survival. Nitrogen isnt poisonous but it cant support life on its own either. The three mixed together in the right proportions is breathable over the long term (air)

    Penacillin type antibiotics dont work on resistant strains on their own and drugs that inhibit the enzymes that bacteria use to neutralize those antibiotics wont do anything on theur own but together, they can kill bacteria that used to be vulnerable to antibiotics but developed resistance to them.

    Alloys are examples of materials that are greater than the sum of their parts.

    Sulfur, charcoal and saltpeter are relatively unremarkable. Sulfur and charcoal burn but not particularly violently. Saltpeter doesnt do much unless it is paired with fuel. Together they make gunpowder.

      For what it’s worth, there’s much more argon and water vapor in the air (each around 1%) than there is CO2 (around 0.04%).

        I am well aware that air isn’t just Oxygen, Nitrogen and Carbon Dioxide. I didn’t mention these other components because they are not relevant to the point I was making. CO2 concentrations can easily exceed 1,000 ppm indoors and in heavily populated cities. CO2 really only drops to around 400 ppm far away from populated areas. Your body relies on CO2 concentration in your blood (technically bicarbonate) to stimulate breathing. It does not use Oxygen concentration to do so. This is why some industrial environments can be incredibly dangerous if Nitrogen, Argon etc. displace Oxygen. Youll breathe in and out just fine until the lack of Oxygen knocks you unconscious.
