Distinguish raw data, treated data, and results.

The following densities of water were obtained by Student A: 1.09g/mL, 1.14g/mL, and 1.15g/mL.Determine the average and standard deviation of the density.

If you chose 6 reading for Water-Cut Analyzers (BS&W) macheen, Answer the qustions: Day1 Day2 Day3 Day 4 Day 5 Day 6 0.05 0.06 0.07 0.05 0.04 0.05  - Evaluate the accuracy and precision of the selected data.  - Estimate the sources of errors in selected data (systematic & random error). - Explain the effect of these errors in the process.

All changes save 7. When two solutions are mixed, a color change occurs. The data tables show the time between mixing and the color change for two sets of conditions. For Condition One, the solution concentrations were constant and temperature varied. For Condition Two, the temperature was constant and concentrations varied. Condition One: Concentration Time for Temperature (°C) Sample Color to Change 1 10° 36 sec 22° 14 sec Condition Two: Temperature Time for Concentration Sample Color to % Change 1. 100% 15 sec 2. 50% 24 sec Which of these statements is true according to the data? O The reaction rate is greater at 22°C than at 10°C. O Reducing the temperature increases the rate of the reaction. The reaction is affected by changes in temperature not by changes in concentration. O Decreasing the concentration increases the reaction rate. PREVIOUS 17 of 25 NEXT SAVE & EXIT

Design and construct a data table. Be sure to give the table a title.

In a particular trial, a student got a value for R of 0.083. Calculate the percent deviation of this result. Enter a number without the % sign. The percent deviation should be reported as a positive value.
