  • 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
  • Why is it important to make sure all the NaHCO3 has reacted . . . - Socratic
    You don't want a buildup and accidental excess of HCl to clean Basically, you don't want to add too much acid or else the NaHCO_3 will be completely used up and the excess acid with then have to be neutralized with more base
  • 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
  • How do the solubilities of metal carbonates, and metal bicarbonates . . .
    How do the solubilities of metal carbonates, and metal bicarbonates compare? How does #"lime water"# react with carbon dioxide?
