Then the rate of diffusion for each molecule is calculated by converting the radius from millimeters to micrometers and dividing the resulting number by the number of minutes the plates were sitting. * Diffusion in liquid -room temperature water -crystal of KmnO4 -ruler A glass Petri dish is filled with room temperature

Importance Of Following Orders I am writing this essay on the importance of following order because I recently disobeyed a few General orders. Our commanders put out orders and make them very clear to us for multiple reasons. One of the main reasons is that these orders are there to protect us as Soldiers and not only our images but the images of our fellow Soldiers and the Army itself. The Army and our commanding officers have our best interests at hand and they put in place the orders they do for

Importance of Following Orders The importance of following orders is that if one person breaks off and does whatever they want it can leave others weak and vulnerable. Being in that state‚ others can be subject to extreme conditions and injury. There are reasons why regulations and protocols have been put in the places they have‚ to prevent chaos. There is usually a good reason that an order is given to a subordinate of lower grade. Although there can be times where an order can be unlawful

The Effect of Varying Molecular Weights on the Rate of Diffusion of Substances August 22‚2012 ABSTRACT The effect of molecular weight on the rate of diffusion was verified by the 2 tests: the glass tube setup and the water agar-gel setup. In the glass tube setup‚ two cotton balls were soaked in the solutions of hydrochloric acid (HCl) and ammonium hydroxide (NH4OH) and were simultaneously placed on both ends of the tubing.NH4OH had a lighter molecular weight of 35 g/mole which diffused

The Importance of Following Orders Following orders is of the utmost importance in the military. Obedience is what enables the military to operate in an organized and effective manner which is clearly very important during challenging military situations. While an individual can question the notion of obedience in daily life‚ this luxury is often not available in the military where the grand goals and aims require smooth internal functioning and hierarchical coordination. Indeed‚ many of the standards

ABSTRACT The effect of molecular weight on the rate of diffusion was measured using two tests namely: the glass tube test and the agar-water test. The set-up of the glass tube test used two cotton balls of the same size. One cotton ball is moistened with hydrochloric acid (HCl) and the other one is moistened with ammonium hydroxide (NH4OH). The two cotton balls were inserted in both ends of the glass tube. NH4OH which has a lighter molecular weight (35.0459 g/mole) diffused with a faster rate (dave=20
