Balance this equation. If a coefficient of "1" is required, choose "blank" for that box. CO + O2 → CO2

CO + O2 → CO2

To balance the equation, the atoms of elements on the left side must equal the atom of same element on the right side.

To balance the equation, put 2 in front of CO and 2 in front of CO2 as illustrated below:

2CO + O2 → 2CO2

The coefficients are 2, 1, 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.
