The reaction for the Haber process, the industrial production of ammonia, is N2(8) + 3H2(8) – 2NH3(8) Assume that under certain laboratory conditions ammonia is produced at the rate of 6.29 mol L-1 s1. At what rate is hydrogen consumed? Round your answer to 2 decimal places.
Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions. Note for advanced students: for all charged species, you may assume the necessary counterions act as neither acids nor bases. relative pH of 0.1 M aqueous solution species H20 4 H,PO4 HNO, (Choose one) NO2 7 OH (Choose one) HF (Choose one) ▼

Anna was asked to identify and explain if the equation CO2 (g) → CO2 (I) was an endothermic or exothermic reaction. However she got it wrong. What is her error and what should the answer have been? Anna's statement: The equation is an endothermic reaction because the energy is released from gaseous CO2 to the surroundings to become liquidCO2 causing the molecules to speed up.
