A mixture of gases includes helium, neon, argon and krypton. The partial pressures are as follows: Partial pressure, mm Hg
He 127
Ne 103
Ar 128
Kr120
Carbon dioxide gas is added to the mixture until the total pressure is 2.00 atm. What is the partial pressure
of carbon dioxide in the mixture? Round your answer to the nearest mm Hg without units.

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.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
