Hydrogen peroxide is a chemical compound made up of two hydrogen atoms and two oxygen atoms. It is a pale blue liquid that is often used as a disinfectant or bleach, and it can be found in many household cleaning products.
One interesting experiment that can be done with hydrogen peroxide is the potato experiment. This experiment involves cutting a potato into thin slices and soaking them in a solution of hydrogen peroxide for a period of time.
To perform the experiment, you will need the following materials:
- A potato
- Hydrogen peroxide (3% concentration)
- A plastic container or bowl
- A knife or potato slicer
- A timer or clock
To begin, slice the potato into thin rounds using the knife or potato slicer. You can cut the slices as thin or as thick as you like, but thinner slices will likely react faster to the hydrogen peroxide solution.
Next, fill the plastic container or bowl with enough hydrogen peroxide to cover the potato slices. Carefully place the potato slices into the solution and set a timer for 10 minutes.
As the potato slices soak in the hydrogen peroxide, you will begin to notice some bubbling and foaming. This is due to the release of oxygen gas as the hydrogen peroxide decomposes. The oxygen gas is what causes the bubbling and foaming, as it becomes trapped in the potato slices.
After 10 minutes, remove the potato slices from the solution and place them on a plate or paper towel to dry. As the potato slices dry, the oxygen gas will escape, and the bubbling and foaming will stop.
You may notice that the potato slices have changed color after soaking in the hydrogen peroxide solution. This is due to the bleaching effect of the hydrogen peroxide, which can lighten the natural color of the potato slices.
Overall, the potato experiment is a simple and fun way to demonstrate the decomposition of hydrogen peroxide and the release of oxygen gas. It is a great way to introduce students to the concept of chemical reactions and the properties of hydrogen peroxide.
Victor Vroom Expectancy Theory
Hence, as per Skinner, the outer environment of the association must be outlined successfully and decidedly in order to inspire the representative. The magma chamber is currently filling again, and the land surface in Yellowstone is rising or tilting a slight amount each year. Challenge employees to reach their full potential with Managers can use the expectancy theory to motivate employees by expressing trust in their abilities to handle their duties, despite perceived difficulty and control. What are the disadvantages of expectancy theory in organization? A lot of people fail at motivating themselves before they even start because, often times, the goal they're going after isn't one they actually want. Second, they must also believe that there is a high probability that theur performance will lead to their desired outcomes. Employees who perform well get larger compensation increases; those who do not perform satisfactorily receive little or no increase in compensation. The Rocky Mountains include at least 100 separate ranges, which are generally divided into four broad groupings: the Canadian Rockies and Northern Rockies of Montana and northeastern Idaho; the Middle Rockies of Wyoming, Utah, and southeastern Idaho; the Southern Rockies, mainly in Colorado and New Mexico; and the Colorado Plateau in the Four Corners region of Utah, Colorado, New Mexico, and Arizona.

Assuming you have a goal that gets you excited, the next thing to do is devise a plan that results in increased performance over time. Found insideGemma knew it instantly, recognized the path she'd taken to the exact spot where she now saw herself standing. It also states that anything below that might be welcomed, but will not lead to substantially greater effort on the part of employees to increase business results. Generally, the ranges included in the Rockies stretch from northern Alberta and British Columbia southward to New Mexico, a distance of some 3,000 miles 4,800 km. If you can maximize all three of these relationship types by pulling one of the three levers above valence, expectancy, instrumentality , you can increase motivation, both for yourself as well as those around you. Some of these thrust sheets have moved 20 to 30 miles 32 to 48 km to their present positions.

Found inside Page 380The exact place is almost the center lengthwise and one fourth from the lower side , the spot marked with a small circle on the fifth figure. Above surrounding basins it includes the large Athabasca Glacier, part of the Kaibab Upwarp in the United States into. Expectancy measures your belief that your increased effort will lead to increased performance. Expectancy theory examples One of the most common expectancy theory examples is people working harder when they believe the added effort will help them achieve a goal and be rewarded. What are strengths and weaknesses of expectancy theory? Found inside Page 161Being a Correct and Impartial Narrative of the Chase, Trial, Capture, and Execution of Henry he informed the captain of the exact position of affairs. So, if you're training someone, you want to drive the point home that if they try hard and increase their performance, it'll be noticed and rewarded. These four factors are positive reinforcement, negative reinforcement, punishment, and extinction.
