Given the balanced equation: C₃H₈ + 5O₂ → 3CO₂ + 4H₂O , what is the total number of moles of O₂ required for the complete combustion of 1.5 moles of C₃H₈?

7.5 Mol O2

Explanation:

1.5 mol C3H8 × 5 mol O2 ÷ 1 mol C3H8 = 7.5 mol O2

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
