Which one is it?

A chemical is sprayed onto a lawn at a rate of 0.90 kg active ingredient per hectare. The chemical has a half-life of 30 days at 20C. A storm event occurs 15 days after application and causes 3.5% of the material present in the 25 hectare field to be lost (total losses). If average temperatures during the 15-day period were 17C, how much material (mass) was lost during the storm?

What is the significance of selecting a "representative" sample for chemicalanalysis, and how does this practice ensure accurate and reliable results withrespect to chemical analyses?

Using the calculated results in the picture attached, starting at 15 minutes, calculate the rate constants, k (last column in the data sheet). Then calculate the average value of k. Use the following equation to help calculate: ln (a/a0) = -kt
