Let’s find out if we can be ready for a test on Thursday 3/06!
Br2 I2 O2
What is the molar ratio of iron(III) sulfate to sodium sulfate when iron(III) sulfate reacts with sodium carbonate? Fe2(SO4)3 + 3Na2CO3 Fe2(CO3)3 + 3Na2SO4
1 mole Fe2(SO4)3 = 3 moles Na2SO4
If 10 moles iron (III) sulfate reacts, how many moles sodium carbonate will form?Fe2(SO4)3 + 3Na2CO3 Fe2(CO3)3 + 3Na2SO4
10 moles Fe2(SO4) x 3 moles Na2CO3/1mole Fe2(SO4)3 = 30 molesNa2CO3
15 gO2 X 1moleO/32 gO X 2moles H2O/moleO
= 0.94 moles water
46gNa X 1moleNa/23gNa X 1mole Cl2/2molesNa
= 1 mole Cl2
If 100 g sodium chloride reacts completely with barium, then how many grams sodium metal will be obtained? 2NaCl + Ba BaCl2 + 2Na
100gNaCl x 1mole NaCl/58.4 g NaCl x 2 mole Na/2 moles NaCl X 23 g/1mole Na
=39.32 g Na
(80gA) x(1molA/58.4gA)x (3mol B/2molA)x(6.02x1023molecB)
Na2S2O3(aq) + 4Cl2(g) + 5H2O(aq) 2NaHSO4(aq) + 8HCl(aq)How many moles of H2O react if 5.24 x 1019molecules of HCl are formed?
(5.24 x 1019 molec A) x (1molA/6.02 x1023 molec A)x(5 molB/8molA)
