Why does the nozzle not melt even when the melting point of titanium at 1668 degree Celcius, and the flame of the flame is up to 3200-3500 degree Celcius.
It is easy to produce hydochloric acid from hydrogen chloride by simply dissolving it into water or even with room humidity, it is sufficiently to form dense white fumes of hydrochloric acid.
But is it possible to produce or extract hydrogen chloride from hydrochloric acid?

Simple maths but i don't understand why (about recurring/repeating decimals)
When calculating recurring decimals, we let X to be that number to calculate it for example:
0.4* = x
4.4* = 10x
10x - x = 4.4* - 4*
9x = 4
x = 4/9
Therefore 0.4* = 4/9
But I when I...
well, i think it depends on which part of the body hits the wall first and the speed of the car before collision because mometum is the product of speed and mass of the object and i don't think flying in a car will reduce much velocity by the friction of air and body.
Three fatty acid, when condense with glycerol, they donate or give out their OH- ions and combine with the H+ ions to form water and fat molecule. According to my chemistry teacher, an acid is a covalent molecular compound, which when dissolved in water, forms hydrogen ions H+ (aq). As fatty...
