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:]
Material that absorbs or reflects all light that reaches it is called opaque.
An object is translucent when it allows some light to go through and reflects the others It is transparent when all light goes through it. Pigmented on the other hand changes the color of the light.
