Hydrogen peroxide can be used to disinfect and clean surfaces around the home. It breaks down over time into oxygen gas and water. Some amount of hydrogen peroxide (H2O2) reacts to produce 1 molecule of oxygen (O2) and 2 molecules of water (H2O)

H: Number of atoms in the reaction: 4
O: Number of atoms in the reaction: 4

During this reaction, how many molecules of hydrogen peroxide (H2O2) react?

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.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
