C9H20 + 14O2 --> 9CO2 + 10H2O
Answer for your question is;
2,6 = 8
The first shell is 2 electrons the other shell is 6 electrons
The average rate of reaction over a given interval can be calculated by taking the difference of concentration on a particular given reactant, and dividing it by the total time. In this case, (1.00 M - 0.655 M)/30 s = 0.0115 M/s, or 0.0115 mol/L-s, and this is the final rate of reaction.
