Answer:
1.5 moles of CO₂ are produced
Explanation:
Based on the chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O<em> -The reaction of the question is wrong-</em>
5 moles of oxygen reacts per mole of propane, C₃H₈, to produce 3 moles of CO₂ and 4 moles of water.
If 2.5 moles of oxygen react and, 5 moles of oxygen produce 3 moles of CO₂, moles of CO₂ produced are:
2.5 moles O₂ * (3 moles CO₂ / 5 moles O₂) =
<h3>1.5 moles of CO₂ are produced</h3>
Answer:
The Hydrogen gas produced during its reaction with metal gets oxidised to H2O, hence no hydrogen gas is produced. Instead it evolves nitric oxides such as NO2,NO etc.
Answer:
About 277 Kelvin
Explanation:
Take the celcius, and add 273.15 to it
4°C + 273.15 = <u>277.15K</u>
And round the answer to the nearest whole
277.15K ≈ 277K
