Answer is: 55.125 grams <span>of propane must be burned.
</span>Balanced chemical reaction: C₃H₈ + 5O₂ → 3CO₂ + 4H₂O.
Make proportion: 1 mol(C₃H₈) : 2220 kJ = n(C₃H₈) : 2775kJ.
n(C₃H₈) = 2775 kJ·mol ÷ 2220 kJ.
n(C₃H₈) = 1.25 mol.
m(C₃H₈) = n(C₃H₈) · M(C₃H₈).
m(C₃H₈) = 1.25 mol · 44.1 g/mol.
m(C₃H₈) = 55.125 g.
n - amount of substance.
I don't learn chemistry yet but I see where you are right now... I think this will change in the near future because we will only have the ocean water to survive... So we purify the water... Because this will almost be all we have, we'll have no choice BUT to make money on this.... Sorry if it's wrong I don't learn chemistry yet
Answer: 1.788 volts.
Explanation:
To solve this problem we can combine battery cells to create higher voltages. Building more lemon batteries and connecting them with a metal wire from "+" to "-" adds the voltage from each cell. The two lemon batteries above, combine to produce a voltage of 1.788 volts.
Answer: Examples of pure substances include iron, aluminum, silver, and gold. Mixtures: Substances that have two or more different particles are mixtures. Examples of mixture include the salt solution which is a 'mixture' of two components, salt, and water.
