In order to determine the concentration of a given potassium Iodide solution. 25 cm of 0 .3 percent Hydrogen Peroxide (0.3w/v) was pipetted unto 50 cm of the Potassium
lodide solution followed by addition or 2 drops of bench HC. The mixture was allowed
to stand for 15 min. The liberated lodine was tired against o 1 M standard Sodium
Thosphate solution
0,5 cm of starch indicator was added when the colour of the lodine was featly
discharged and the titration continued to obtain the end-point. Using an average titrea
25 cm and correct equations of reaction,
Convert the concentration of the Hydrogen peroxide to mol/L
Estimate the concentration of the Possun lodide in the solution provided.

Juju.01) 5 geologic events a group of students designed an experiment in an ice rink to represent the solar system. the steps of the experiment are listed below. 5: geologic events 1. choose a student to represent the sun. the planets are represented by two tennis balls. 2. ask the student to hold the tennis balls in each palm and spin on the ice with arms stretched out. 3. ask the student to draw in the arms after about 10 spins. 4. observe the student's arms rotate faster when they are closer to the body. 05 geologic events enors) the experiment most likely demonstrates that (2 points) 07 discussion-based sessment/module planets exert gravitational force on the sun the sun exerts gravitational force on the planets 3.07 discussion-based ssessment speed of a planet depends on its distance from the sun new version available!
