Study the following reaction carefully. what classification should this reaction have? 4al + 3o 2 2al 2 o 3 synthesis decomposition single replacement double displacement

 4 Al  + 3O₂ →  2Al₂O₃

The  classification  of  above reaction is   synthesis

Explanation

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
