Straight sodium is very reactive. When it contacts water, it quickly reacts according to the equation 2Na + 2H2O -> 2NaOH + H2. You may recognize NaOH by it's common name - lye.
Chlorine gas is likewise very reactive.
If you get the two of them together, however, you get 2Na + Cl2 -> 2NaCl + a lot of heat. Once the NaCl has formed, it is very stable and doesn't want to react with anything else.
When cyanoacrylate is heated, it undergoes an exothermic polymerization reaction, forming long chains of polymeric material known as poly(cyanoacrylate). When mixed with sodium hydroxide, cyanoacrylate undergoes an anionic chain reaction leading to the formation of a different polymer called poly(alkyl cyanoacrylate). Both reactions involve the rapid bonding of molecules, leading to the formation of a strong adhesive material.
You can determine wind direction by wetting your finger and holding it up in the air and feeling which side of your finger is being hit by the air. This would mean that the wind is coming from that direction.
No, a fingernail is not considered a mineral. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystalline structure, whereas a fingernail is made up of keratin, a protein produced by living organisms.
A very soft rock like gypsum or talc would be scratched easily with a finger. Rocks like quartz, granite, or diamond would not be scratched by a finger.
KOH is potassium hydroxide, an Arrhenius base. All ionic compounds are soluble (they ionize in the polar water). This particular ionic compound also has all these loose hydroxide anions in solution, making it a base. never drink, or stick your finger in it, it burns like heck! looks like water, tastes like death.

Not in English. It comes from a compound word meaning "wing-finger" in Greek.
Chlorine, because it is a chemical, can fade or chip finger and toe nail polish. To lessen the chance of your nail polish chipping, make sure to apply a clear topcoat before and after you paint your nails. And, once you get out of the pool, dry off your nails with a towel to keep the chlorine from sinking in. Hope this helps!
If it is a candy yes, but if you are referring to the metaphor no.
No, pencils nowadays do not actually contain poisonous lead so you'll be fine:)
The scientific or taxonomic name would be Euphorbia tirucalli.
Finger nails are an organic compound as they mainly consist of keratin, a protein that is produced by living cells in the body. Keratin is a complex organic molecule that gives nails their structure and strength.
Yes, a finger nail clipper can be considered a compound machine because it consists of multiple simple machines working together. It has a lever for applying force to cut the nail and a wedge (the cutting edge) to separate the nail from the finger.
Mercury has a high surface tension. NB Don't try it yourself, mercury is very poisonous.
