becomes very hot and it looks like it is boiling
acid + metal -> metal salt + hydrogen
hydrochloric acid + magnesium -> magnesium chloride + hydrogen
2HCl (l) + 2Mg (s) -> 2MgCl (s) + H2 (g)
-470,000 joule/mole Mg
Exothermic
Mg + 2HCl = MgCl2 + H2 SO magnesium chloride and Hydrogen gas
Here is an example of a Competition Reaction: Mg+HCL=Mg+H2 This equation is not balanced.
HCl is the limiting reagent.
MgCl, H2O and CO2 are produced in a reaction between HCL and MgCO3.
Mg + 2HCl => H2 + MgCl2 The type of chemical reaction is a Single Replacement.
5.05 g/mol

magnesium chloride
Mg + 2HCl --> MgCl2 + H2
0,75 grams hydrogen
because it is cool
a displacement reaction, magnesium displaces hydrogen because it is more reactive
