The Relationship Between the Rate of Diffusion and Molecular Weight as Observed in Postassium manganate‚ Potassium dichromate‚ and Methylene Blue Elisha Padilla Group 3 Sec. X – 8L March 26‚ 20151 ABSTRACT The relationship between the rate of diffusion and the molecular weight of a substance was determined by introducing three substances (KMnO₄‚ K₂Cr₂O₇‚ C₁₆H₁₈N₃SCl) of different molecular weight to agar-water gel‚ and measuring the distance of diffusion every

Use the postulates of the kinetic theory to explain the following: i)Matter can exist in three states ii)The pressure exerted by a confined gas decreases as its temperature is lowered iii)A gas of low molecular mass will diffuse through air faster than a gas of high molecular masseven though both are at same temperature. The Kinetic Theory can be used to describe the three physical states of matter namely‚ solid‚ liquid and gas. In this theory‚ some basic assumptions has to be made: a) all matter

Titan is the largest moon of Saturn. It is the only natural satellite known to have a dense atmosphere‚[9] and the only object other than Earth for which clear evidence of stable bodies of surface liquid has been found.[10] Titan is the sixth ellipsoidal moon from Saturn. Frequently described as a planet-like moon‚ Titan has a diameter 50% larger than Earth’s natural satellite‚ the Moon‚ and is 80% more massive. It is the second-largest moon in the Solar System‚ after Jupiter’s moon Ganymede‚ and

narrow further still into capillaries. After the tissue has been perfused‚ capillaries branch and widen to become venules and then widen more and connect to become veins‚ which return blood to the heart. Capillaries (pronounced /ˈkæpəˌlɛri/) are the smallest of a body ’s blood vessels and are part of the microcirculation. They are only 1 cell thick. These microvessels‚ measuring 5-10 μm in diameter‚ connect arterioles and venules‚ and enable the exchange of water‚ oxygen‚ carbon dioxide‚ and many other

Order getter Definition The role most synonymous with selling is a position in which the salesperson is actively engaged in using their skills to obtain orders from customers. One highly challenging yet potentially lucrative example of this are sales positions where the main objective is to find new customers. Sales jobs in this category are often in fields that are very competitive‚ but offer high rewards for those that are successful. The key distinguishing factor of these positions is that

The concept of order-winners and order-qualifiers is originating from an attempt to explain how internal operational capabilities can lead to competitive advantage‚ market success and answer the following : - What drives customers in buying the products manufactured by a company at all. - What makes customers purchase a certain product instead of a similar one manufactured by a competitor. In order for customers to purchase a product a car for example it needs to meet a set of minimum requirements

Clostridium Difficile People getting medical care can catch serious infections called healthcare-associated infections or HAI’s. One type of HAI which is caused by the germ Clostridium Difficile or C-Diff. In 2015 it was estimated almost half a million infections in the United Ststes‚ and 29‚000 died within 30 days of the initial diagnosis. Those most at risk are older adults‚ who take antibiotics and also get medical care. The CDC provides guidelines and tools for the healthcare population to help
