Answer:
Sodium hydroxide, a base, reacts with sulfuric acid to form sodium sulfate (complete neutralization) and water. If you write the balanced equation, you will see that 2 moles of sodium hydroxide react with 1 mole of sulfuric acid to form 1 mole of sodium sulfate and 2 moles of water. Therefore it would take .25 moles of sulfuric acid to react with .5 moles of sodium hydroxide.
Explanation:
Answer:
93%
Explanation:
First write the balanced reaction
C3H8 + 5O2 --> 3CO2 +4H2O
2nd, find the theoretical yield
2L C3H8 (1mol/22.4L) (3 mol CO2/1 molC3H8) (22.4 L/ 1mol) = 6L
3rd, Find percent yield
%yield = (actual / theoretical) x100 = (5.7/6) x 100 = 93%
