Answer: balanced reaction equation
C8H18(g) + 25/2 O2(g) ---------> 8CO2(g) + 9H2O(l)
Explanation:
Part A- coefficients
1, 25/2,8,9
Part B
Oxygen is the limiting reactant
Part C
If 1 mole of octane produced 9 moles of water from the balanced reaction equation
0.28 moles of octane will produce 0.28×9= 2.52 moles of water
Part D
If 12.5 moles of oxygen reacts with 1 mole of octane
0.63 moles of oxygen will react with 0.63/12.5=0.0504moles of octane
Amount of octane left= 0.280-0.0504=0.2296 moles
The electron configuration of Nitrogen is
1s ^2 2s ^2 2p^ 3
There are 3 electrons in the 2p sub level of nitrogen.
Balanced Equation: H2SO4 + 2NaOH --> 2H2O + Na2SO4
Moles= Mass/RMM
= 65.5/40
= 1.6375
Mole Ratio = 2:2
= 1.6375
Mass (H2O) = 1.64 x 18
= 29.5 g
