Transcription of Stoichiometry with Solutions Problems - LSRHS
1 Stoichiometry with SolutionsName + 3 NaOH --> Na3PO4 + 3 H2 OHow much M H3PO4 is needed to react with 100 ml. of M NaOH? HCl + Zn --> ZnCl2 + H2 When you use 25 ml. of M HCl to produce H2 gas, how many grams of zinc does it react with ?What volume of H2 gas is produced at STP? + 2 HCl --> CaCl2 + H2O + CO2 How much M HCl would be needed to dissolve a CaCO3 pearl which weighs grams? Fe + 2 Au(NO3)3 --> 3 Fe(NO3)2 + 2 AuThrowing some scrap iron in a gold nitrate solution causes the gold metal to precipitate. How much M gold nitrate solution would react with 224 grams of iron metal? water is about M NaCl. To produce Cl2 gas, a company evaporates sea water, melts the NaCl, and runs electricity through it. 2 NaCl --> 2 Na + Cl2 How many liters of sea water are needed to fill a tank car with 1,120,000 liters of chlorine gas at STP?
2 + 3 NaOH --> Na3PO4 + 3 H2 OIf ml. of H3PO4 react exactly with ml. of M NaOH, what is the concentration of the phosphoric acid?Answers: 1) 17 mL2) g of zinc and L of H2 3) ) L5) x105 L6) M
