The log(mg kg1) for one soil sample (that is, the Sn content in [mg Sn (kg soil)*1], is found to be log(mg kg1) = 2.22. What is the tin content of the soil in [mg Sn (kg soil)-²]? Your Answer: Answer unitsAn object was left in a room of unknown surrounding temperature. The temperature of the object was summarized below with respect to the time t (in minutes) the object was initially observed. Predict and complete the information, i.e. determine the temperature in Celsius when t = 30 minutes. Put your answer accurate up to four decimal places. No need to put in the units of measurement. When t = 0, the temperature of the object is 30 degrees Celsius. When t = 10 minutes, the temperature of the object is 32 degrees Celsius. When t = 20 minutes, the temperature of the object is 33.6 degrees Celsius. When t = 30 minutes, the temperature of the object is unknown.
