Ammonia gas reacts with hydrogen chloride according to the reaction given below, which must also be balanced. if 7.00g of NH3 is reacted with 12.0g of HCl in a 1.00L container at 25C, what will the final pressure, in atmospheres, be in the reaction container? (the product is a solid, it has NO vapor pressure) __NH3 (g) + __ HCl (g)--> __NH4Cl (s)
