Answer:
The answer to your question is 4
Explanation:
Chemical reaction
C₂H₆ + O₂ ⇒ CO₂ + H₂O
Reactants Elements Products
2 Carbon 1
6 Hydrogen 2
2 Oxygen 3
Balanced chemical reaction
2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O
Reactants Elements Products
4 Carbon 4
12 Hydrogen 12
14 Oxygen 14
When the reaction is balanced the coefficient for CO₂ is 4.
Answer:
<em><u>V = 25 m/s</u></em>
Explanation:
From first equation of motion, V = U + at
V = 10 + ( 5×3 )
V = 25 m/s
The masses of CO and CO2 are 90.55g and 100−90.55=9.45 g respectively.
<h3>Total mass.</h3>
Let the mixture has 100g as total mass.
The number of moles of CO is 2890.55=3.234.
The number of moles of CO2 is 449.45=0.215.
The mole fraction of CO is 3.234+0.2153.234=0.938.
The mole fraction of CO2 is 1−0.938=0.062.
The partial pressure of CO is the product of the mole fraction of CO and the total pressure.
It is 0.938×1=0.938 atm.
The partial pressure of carbon dioxide is 0.062×1=0.042 atm.
The expression for the equilibrium constant is:
Kp=PCO2PCO2=0.062(0.938)2=14.19
Δng=2−1=1
Kc=Kp(RT)−Δn=14.19×(0.0821×1127)−1=0.153.
