<h3><u>Answer</u>;</h3>
17.25 moles of hydrogen
<h3><u>Explanation;</u></h3>
The equation for the reaction;
2HI (g) → H₂(g) + i₂ (g)
34.5 moles of Hydrogen iodide are decomposed;
The mole ratio of HI to Hydrogen = 2 : 1
Therefore;
moles of hydrogen = (34.5/2) ×1
= 17.25 moles
Therefore; 17.25 moles of hydrogen will be produced when 34.5 moles of Hydrogen iodide are decomposed
Answer: There are 105 grams of acetylene in the tank.
Explanation:
According to ideal gas equation:
P = pressure of gas = 1.39 atm
V = volume of gas = 70.0 L
n = number of moles = ?
R = gas constant =
T = temperature of gas in Kelvin =
Mass of ethylene , M = Moles × Molar mass = 4.04 mole × 26 g/mol =105g
Thus there are 105 grams of acetylene in the tank.
