H2, on Runescape may be a herald number e.g Rune Helm (h2) or Black Kite Shield ( h2 )
where as 2h means 2-handed, as in Dragon 2h sword, meaning Dragon two handed Sword.
H2 is the symbol for the diatomic molecule of hydrogen; 2 H meaning is two hydrogen atoms.
H2, on Runescape may be a herald number e.g Rune Helm (h2) or Black Kite Shield ( h2 ) where as 2h means 2-handed, as in Dragon 2h sword, meaning Dragon two handed Sword.
The equation for the incomplete combustion of hydrogen is 2H₂ + O₂ -> 2H₂O + energy (incomplete combustion).
2 HCl + Pb --> PbCl2 + H2 (for Pb 2+) 4 HCl + Pb --> PbCl4 + 2 H2 (for Pb 4+)
The net ionic equation for the reaction between hydrochloric acid (HCl) and magnesium (Mg) is: 2H⁺ + Mg(s) -> Mg²⁺ + H₂(g)
Hydrogen gas (H2). Zn + 2H+ -> Zn(2+) + H2(gas)
Zn + 2H+ ----> Zn2+ + H2
2Si +2HF-2siF + 2H
if you mean lead the metal: Pb + 2H+ --> Pb+2 + H2
they are usually acquired from monster drops, though for p2p members there is a 2h sword shop in Taverly.
2H+2H2O gives 2KOH+H2
Copper will not react with hydrochloric acid. Cu(s) + HCl(aq) ---> No reaction
