Based on the replacement reaction, what would the products of the reaction be? BeSO4 + 2NH4OH → Be(
)2 + (NH4)2SO4

BeSO₄ + 2NH₄OH → Be( OH)₂ + (NH₄)₂SO₄

Given

Reaction

BeSO₄ + 2NH₄OH → Be( ...)₂ + (NH₄)₂SO₄

Required

The products

Solution

There are two possible displacement reactions

Single replacement if one element replaces or reduces another element in the compound and forms a new compound

A + BC ⇒ AC + B

Double replacement if both the cations and anions of the two compounds in the reactant swap positions to form 2 new compounds in the product

AB + CD ⇒ AD + CB

Thus, the product is Be(OH)₂

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.
