How can you make a room sound proof? Why is the possible?​

Soundproofing walls involves ripping the existing drywall off the walls (and perhaps the ceiling), filling the walls with fiberglass insulation, attaching metal strips called “resilient channel” to the studs, and fastening new drywall to the channel.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
