natural abundances vary based on the planet and its formation history for example Mars and Earth have different oxygen isotope ratios it has been suggested that the moon was formed when a planet-sized object struck a glancing blow on Earth although The Corrs remained largely intact the remittance of these two bodies eventually reform into Earth and Moon explain how you could use isotopic analysis to support this Theory

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
