In some vintage science fiction movies, space travelers find themselves on a planet orbiting a distant star in which there are curious forms of life based on silicon instead of carbon. although the story clearly is sci-fi, there is an aura of plausibility in the choice of silicon, an atom with 14 protons, in place of carbon as this alien life-form's central atom. the reason is that silicon:

Aroom with dimensions 7.00m×8.00m×2.50m is to be filled with pure oxygen at 22.0∘c and 1.00 atm. the molar mass of oxygen is 32.0 g/mol. how many moles noxygen of oxygen are required to fill the room? what is the mass moxygen of this oxygen?

How many atoms are in 2 moles of phosphorus?

Question 17 hydrogen is manufactured on an industrial scale by this sequence of reactions: +ch4gh2og ⇌ +cog3h2g k1 +cogh2og ⇌ +co2gh2g k2 the net reaction is: +ch4g2h2og ⇌ +co2g4h2g k write an equation that gives the overall equilibrium constant k in terms of the equilibrium constants k1 and k2. if you need to include any physical constants, be sure you use their standard symbols, which you'll find in the aleks calculator.
