At a certain temperature and pressure 2.1 L of H2 reacts with 2.1 L of I2. If all the H2 and I2 are consumed, what volume of HI, at the same temperature and pressure, will be produced?
Consider the following reaction: 2 HI(g) -> H2(g) + I2(g) If 3.55 moles of HI(g), 0.550 moles of H2, and 0.630 moles of I2 are at equilibrium in a 1.00 L container at 915 K
Starting with 0.86 moles of HF, calculate the number of moles of H2O that is produced by this balanced reaction.
