Why was Aristotle considered correct over Democritus based on their time period

3Fe + 4H2O Fe3O4 + 4H2 1) How many molecules of H2 are produced? 2) How many oxygen atoms are found in the products? 3) How many moles of Fe3O4 are formed? 4) What is the ratio of the number of moles of Fe atoms to the moles of H2O molecules?

The overall chemical equation resulting from the sum of the following three steps is 2C (s) + 2H2O (g) → 2CO (g) + 2H2 (g) CO (g) + H2O (g) → CO2 (g) + H2 (g) CO (g) + 3H2 (g) → CH4 (g) + H2O (g) a. 2C (s) + 2H2O (g) → CO2 (g) + CH4 (g) b.

1. A food sample is burned in a calorimeter that contains 2000. g of water. The temperature increases from 22.0°C to 44.3 °C. How many Calories does the food sample contain, assuming all of the energy from the food was transferred into the water?

Why doesn't water light on fire? It has all the ingredients except heat! Hydrogen for the flammability factor, oxygen so it can keep burning, and all you need to do is add heat and BOOM you have a flame! 15 pts
