A 5.0 L air sample at a temperature of -50.0degreeC has a pressruer of 800 mm Hg. What will be the new pressure if the temperature is raised to 100.0degreeC and the volume expands to 7.0 L? (This one excludes the n1 and n2)

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.
