It is a double replacement reaction, also called a double displacement reaction.
Single replacement A+
Do you mean 2NaCl + H2SO4 → Na2SO4 + 2HCl ? This is a double decomposition (also known as double displacement) reaction. The hydrogen and sodium cations are switching their respective anions.
There are two types of elements, sodium (Na) and chlorine (Cl) in NaCl and they exist as ions: Na+ and Cl- ions
metal + acid >>> metal salt + hydrogen this is what i was taught anyway ;D
A waterfall is not a chemical reaction.

A decomposition reaction breaks up compounds into simpler constituents. The pattern for this reaction is AB --> A + B. An example is the electrolysis of sodium chloride (NaCl) into elemental sodium and chlorine, 2NaCl --> 2Na + Cl2.

A chemical reaction.
Its irreversible and an oxidising reaction
exothermic
metal + acid >>> metal salt + hydrogen this is what i was taught anyway ;D
It is:2Na(s) + Cl2(g) → 2NaCl(s)(But remember in exams you should know this kind of method) Peace out, add me on BBM its:12b6a7d9
double-displacement reaction.
