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

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.

Please answer questions 3 and 4 and show work please. Thank you

The answer is supposed to be C though, it was a provincial question in the Chem 12 august 2005 exam. Why is it C?

Below is a simple set of weights obtained while immersing potato slices in various sugar solutions over 30 minutes. I need help calculating all of this for a 30 min period  a. For each solution, calculate the rate of weight change over this 30-minute period. Show your work in the space below. Once you calculate these rates - fill in the blanks below and then add these answers to your Canvas exam. Write your answer in standard notation and use  3 digits past the decimal point - e.g. 0.005, 0.030. (Note that the last zero in an answer is considered to be a digit). Show your work in the space below.  0.0 M sucrose = _______  _____________ g/min 0.4 M sucrose = _______ ____________ g/min 0.6 M sucrose = ________ ____________ g/min 0.8 M sucrose = ____________________ g/min 1.0 M sucrose = ________   __________ g/min Using the osmosis data in the question above, determine the percent weight change for each sucrose solution and fill in the blanks given below and then add these answers to…
