When we have Kw = 1.2x10^-15
and according to Kw formula:
Kw = [OH-] [H+]
by substitution:
1.2x10^-15 = [OH-][H+]
when the solution is neutral that means:
[OH-] = [H+]
∴1.2X10^-15 = X^2
∴X = 3.46 x 10^-8
∴[OH-] = [H+] = 3.46x10^-8
2H2S(g)⇌2H2(g)+S2(g) I have calculate my delta H which is 168.9 kj/ mol but I ... Given the equation: 6CO2(g) + 6H2O(l) -> C6H12O6(s) + 6O2(g ...
I believe that is condensation
A glow stick contains two chemicals and a suitable dye (sensitizer, or fluorophor). This creates an exothermic reaction. The chemicals inside the plastic tube are a mixture of the dye and diphenyl oxalate. The chemical in the glass vial is hydrogen peroxide.
B. Density
Density = mass/volume because it’s basically the concentration of mass. How much matter takes up the space. If you pack more matter into less space, it is more dense.
