C3H8 + 5O2 → 3CO2 + 4H2O a. How many moles of oxygen are necessary to react completely with fours moles of Propane (C3H8)?

b. How many moles of Propane (C3H8) are needed to produce 25 moles of carbon dioxide?

c. How many molecules of water will 3 moles of propane (C3H8) produce?

heat or electricity in the atmosphere- c.

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
