10 hectometers
One hectometer is 100 meters in length already, so 10 is 1000
Nitrogen, for example, is a gas that liquefies at about −200° C and freezes around −210° C, whereas bismuth is a solid melting at 271° C and boiling at about 1,560° C.
Answer: pH = 2.68
Explanation: pH = - log[H3O^+] .
HCl reacts with water : HCl + H2O -> Cl^- + H3O^+
So [H3O^+] = c(HCl) = 0.0021 M
pH = - log(0.0021) = 2.68
