Consider the balanced equation below.
2 answers:
Answer : The correct option is, (2) 8 mole of hydrogen will react with 1 mole of sulfur.
Explanation :
The balanced chemical equation is,
By the stoichiometry we conclude that, 8 moles of hydrogen react with 1 mole of sulfur to give 8 moles of hydrogen sulfide.
Hence, the correct options is, (2) 8 mole of hydrogen will react with 1 mole of sulfur.

Answer: Volume of CO2 is 89127 mL
Explanation: The reaction that takes place is: C2H2 + O2 --> CO2 + H2O
The amount of C2H2 that react allow us to predict the amount of CO2 that will be obtained
26g/1mol is molar mass of C2H2 and 2/4 is the molar relation between CO2 and C2H2 in this reaction. Canceling units, at the end mol of CO2 are obtained
Now with the moles of CO2 and the ideal gases equation is possible to calculate the volumen occupied by the gas.
PV = RnT where P: pressure, V: volume, R: ideal gas constant, n: moles and T: temperature expressed in K (add 273,15 to °C temperature: 37,4°C + 273,15 = 310,55K)
V= RnT/P
To express volume in mL multiply the L result by 1000 which equals 89127 mL
