Hydrogen chloride or most commonly known as hydrochloric acid and
muriatic acid is a diatomic compound that consists of hydrogen and chlorine. It
is prepared industrially by the combustion of hydrogen, H2, in chlorine, Cl2.
H2 + Cl2 -> 2HCl. There are also many metallic chlorides that release
hydrogen chloride gas, HCl, when warmed with concentrated sulfuric acid, H2SO4.
Mostly, it is prepared by heating it with sulfuric acid and sodium chloride.
The reaction is NaCl + H2SO4 -> HCl + NaHSO4. Adding sulfuric acid enables the reaction to proceed further and it acts as a catalyst in the reaction.
They have the same amount of valence electrons
The combustion of methane, CH4, releases 890.4 kJ/mol. That is, when one mole of methane is burned, 890.4 kJ are given off to the surroundings. This means that the products have 890.4 kJ less than the reactants.
No. Of protons = mass no. - no. Of neutrons
No. Of protons = 67 - 37
= 30
No. Of electrons = 28
Zinc will have 30 protons and 28 electrons. So, it will have +2 charge
Symbol - Zn^+2
