The ammonia gas is produced by reacting hydrogen gas with nitrogen gas. How to produce 856 g of ammonia gas using air as your source of nitrogen gas, define what volume of air is needed if the air is introduced at 27°C and 760 mmHg? the mole fraction of nitrogen gas in air is 0.781
When 200ml of 0.11M hydrochloric acid (HCl) is mixed with 800ml of 0.10M methylamine (CH3NH2), write the net ionic reaction that favors products and occurs as the solutions are mixed. Then write the equilibrium reaction that you would use to solve..
The pressure in the stages is such that 8% by mass of the water entering the stage evaporates and leaves as fresh water. If the desalination plant wants to produce 1400.0 gallons of drinking water per day, how many gallons of brine must the plant ..
