Any chance anyone can tell me how ta solve this??? please and thank you... exam in the morning and id love ta know this one! If H2 + I2 = 2HI the no of moles H2 is then 0.00042 so should i be taking these values away from an overall quantity to see whats left to get the HI concentration?? When 0.02 g of hydrogen and 1.28 g…
