Final answer:
Without specific data or a graph illustrating the change in concentration over time, we cannot accurately answer the question about the concentration of a substance at ten minutes and one hour.
Step-by-step explanation:
To determine the concentration of a substance at ten minutes and at an hour, we would need to have specific data that describes how the concentration changes over time. This could come from a graph plotting concentration vs. time, or a mathematical equation derived from experimental data that shows the relationship between time and concentration. Without this specific data, it is impossible to determine the exact concentration at these time points.
With the information provided, which doesn’t specify how concentration changes with time, it's not possible to accurately answer the question about the concentration of a substance at ten minutes and at one hour. If, for instance, you were given a graph like the ones mentioned in the provided references, you could use the graph to find the concentration at the desired time points by looking at where a vertical line drawn at the given time intersects the concentration curve.
