Answer:
A. 15859.2 L or 15900 L
B. 0.629 mol
Explanation:
At STP, one mole is equal to approximately 22.4 L
L or mL is volume, so you are attempting to solve for L or mL.
A.
708 mol x (22.4 L/1 mol) = 15859.2 L (w/ significant figures included - 15900 L)
B.
(14.1 L) x (1 mole/ 22.4 L) = 0.629 mol.
Answer:
4.4 moles of water
Explanation:
Propane is C3H8. Is the chemical equation, you wrote C2H8 which is wrong. Type everything properly and give a check before finally posting the question.
The chemical equation that is given, is not properly balanced. The BALANCED equation would be
C3H8 + 5O2 → 3CO2 + 4H2O
From this balanced chemical equation, we see that 5 moles of oxygen produce 4 moles of water.
5 moles of Oxygen → 4 moles of water
1mole of oxygen →
moles of water
5.5 moles of oxygen → (
× 5.5) moles of water = 4.4 moles of water
∴ The reaction of 5.5 mol of O2 will produce <u>4.4</u> mol of H2O. [Answer:]
Answer:
This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
