Hydrogen peroxide, H, O,,decomposes to produce water and oxygen gas according to the following equation. 2 H2O2(1) + 2 H2O(l) + O2(g) Data were collected determining the concentration of H20, at various times as seen in the table below. Time (s) 0.00 50.0 100.0 150.0 200.0 [H, O,](M) 2.50 1.25 0.625 0.46875 0.3125 Calculate the average rate of change of H,0, between 50 s and 100 s. OM/S Calculate the average rate of change of O, between 50 s and 100 s. OM/s​

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.
