One, how can you not know what magnesium and hydrochloric acid are! Ok, ask someone who can truly explain it in a way you can understand.

Magnesium is an alkali earth metal, found in group two (S - Block) of the periodic table, it forms 2+ ions, and is quite reactive, upon heating it will burn with a brilliant white glow.

Hydrogen Chloride is an acid gas, or when dissolved in water, it forms an aqueous solution known as hydrochloric acid, any hydrogen halide is acidic, with acidity increasing going down the group, the halides are the non-metals in group 7 (P- Block).

Magnesium, or Mg, has two electrons in its outer shell, and obeying the octet rule, that states during bonding an atom will try to gain 8 outer shell electrons, it

I don't get it: I get the Mg2+ + 2Cl- = MgCl2 part but ?
Does any one no Under What Conditions Does 'Magnesium' React With 'Hydrochloric acid'

$Metal + Acid \rightarrow Metal\, Chloride + Hydrogen\, Gas$

These occur under room conditions because the activation energy is low and the reaction is exothermic, that is it releases heat. The heat sort of increase the rate of reaction at a certain time. You'll get to know more about this later, in Chemical Energetics.

What else do you not understand?

Basically,

Mg + 2HCl --> MgCl2 + H2

Oh so silly is just a mono displacement reaction in which mg get oxidised and hcl get reduce and form mgcl2 as product and h2 as by produt

Please, pramod, do not be rude by calling people silly. I wouldn't have know the answer 6 years back. Also, this thread is old now, nearly a year old.
