STOICHIOMETRY INVOLVING SOLIDS, LIQUIDS AND GASES 116.5 of gluca Cala was burned in the prononce of calculate the volume of COMO) that is produced STP CHO (8) + 60mg) C0 (o) + BHOLA) 2. W at volume of 0 250 M HCl is required to completely react with 0 350 g of NacOS? NACO (s) + 2HCl(aq) + 2NaCl(aq) + HOW - COC) 3 Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide. What volume of Co, will be collected at 950 torr and 500°C, when 75.0 g of Caco, react? CaCO(s) → Cao(s) + CO2(g) 4. How many mL of 0.250 M KMnOcare needed to react with 3.36 g of FSO? 10 FeSO4 + 2 KMnO4 + 8 H2SO4 - 5 Fea(SO4)3 + 2 MnSO. + 8H0 + K2SO4 5. Potassium chlorate reacts with hydrochloric acid to produce chlorine gas What mass of KCIOs is needed to make 4.50 L of chlorine at 2.35 atm and 37 0°C? KCIO3(9) + 6HCl(aq) → KCl(aq) + 3Cla(g) + 3H20(1)

Answer 1

1. Collie OG(A) + 60, ca 600,(g, + 6H₂Org) moles of co= 64 molen of C6H12O6 volume of co, at STP (L) = 6x wt (g) Molar volume at Sep (4mot) Mol.wt (g/mol) - 6x volume of CO 22.4 L/mol 16.50g, 180 g/mol volume of co = 12.32L 2. Na₂CO3 (4) + 2HCl cap, 2 Nochcapst the cost CO2 (g) molen of Hice = 2x molen of Na₂CO Molarity & volume (h) = 2x wt (9) Moliwt (g/mol) 0.250 x V = 2x0.350 g 106 g/mol v=0.02641L - 26.41 mL

CaCO3 Cao (s) + Cog moles of CO = molen of Caco PV - wt (g) Molint (g/mol) 950 ahm X VOL) 760 75g 100 g/mol 0.0821 atm-L x 773.15k molk V = 38.085 L 10 Fesou + 2 KMnO + 8 H₂SO4 → 2 MASO + 8 H₂O + K₂SO4 moles of KMnO4 = 2 moten of resou 0.250 M x V = 2 2 2 2 x 3.36g 152 g/mol V = 0.01768 L v = 17.68 mL
