excess hydrochloric acid? - Socratic What volume of carbon dioxide gas, CO 2 , would be produced at STP if 23 40 g of aluminum carbonate reacts with excess hydrochloric acid?
Two tough chemistry questions? - Socratic H_2 = 12 13 moles K_p = 0 143 From the equilibrium constant and final reactant amounts we can calculate the equilibrium amount of ammonia (7 75 moles) Reversin the "ICE" table we now can determine the "Change" in ammonia (6 75 moles) and thus calculate the change in nitrogen (-3 38) and hydrogen (-10 13) from the balanced chemical reaction The initial amount of hydrogen is then the final
Question #52037 - Socratic molar mass of Na_2(CO_3) = 106 grams mole The number of moles = 0 50 moles The concentration is 0 50 moles dm cubed The molar mass of Sodium Carbonate can be found by multiplying the number of each atom times its atomic mass and adding all the masses together 2 x Na = 2 x 23 = 46 1 x C = 1 x 12 = 12 3 x O = 3 x 16 = 48 + Total = 106 The number of moles is the mass divided by the molar mass
Did I predict these reaction products correctly?? Help! Neither answer is correct The first one should have a 2- charge, and the last one should have a charge of 3+ FIRST PRODUCT ["CoCl"_4]^(-) is not right What you have implied is that the cation is "Co"^(3+), which has a coordination number of 6, not 4 "Co"^(2+) has a coordination number of 4 You can see that if you read this It would be ["CoCl"_4]^(2-) It IS blue, and it is tetrahedral
