The products of the reaction between alkali metals and water are a hydroxide and hydrogen:
2 Na + 2 H2O = 2 NaOH + H2
SINCE active metals are more electropositive than of hydrogen it undergoes an displacement reaction. 2Na+2HCl = 2NaCl + H2
This is the reactivity series of metals.
Corrosion is the type of reaction between metals and acids.
Used in welding metals, the reaction of acetylene with oxygen has = -1256.2= -1256.2 .
Iron and copper

You can identify a single replacement reaction because the reactants are a compound + an element. The products of a single replacement reaction are found by switching the element with another element in the compound. Metals switch with metals, non-metals switch with non-metals, and the most reactive element is always in the compound. A double replacement reaction can be identified because the reactants are always compound +compound. The products would also be two compounds but the elements would switch.
By the reaction of some metals with acids salts are obtained.

Metallic bond is the reaction between molecules within metals, called alkali reactive force.
There is no possible reaction. Of the alkali metals, only lithium is small enough to react with nitrogen.
How well it can replace other metals in a reaction. For example iron is more active than copper, because CuSO4 + Fe --> FeSO4 + Cu reaction occurs. And Cu + FeSO4 --> no reaction
