My hypothesis is that if I turn the water to vapor then I will be able to determine the ratio and the amount of moles of the salt and water. This is because by using evaporation I will be able to learn the mass of the salt and of the water needed for n=m/MM which states the amount of moles can be found by dividing mass of the moles by the molar mass. Experiment 1 First I took a crucible‚ a balance‚ and a Bunsen burner and placed them onto the workbench. Then I measured the mass of the empty crucible

6 R’s The 6 R’s are an important checklist. They are used by designers to reduce the environmental impact of products. They can also be used to evaluate the environmental impact of other products. Respect – In order to understand what it means to be a part of the solution‚ you have to begin with respect. Respect for all things: people‚ animals‚ bugs‚ birds‚ fish‚ snakes‚ rivers‚ lakes‚ oceans‚ trees‚ mountains‚ valleys and so on. Rethink — Everything on Earth is connected‚ and every decision

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Polymer Essay: Plexiglass Many of the glass screens and windows we see today are not really made of glass. They are made of plexiglass. Plexiglass is not related to the chemical structure of glass at all. It is an organic polymer. Today this polymer is used in all sorts of applications. The formation of plexiglass was begun in 1930‚ at McGi11 University by William Chalmers‚ a research student. He polymerized methacrylic ethyl ester and methacrylic nitirile‚ creating a clear plastic paste

3.6.2. Hygroscopicity assessment of free films Free films were evaluated for hygroscopicity behavior to understand the contribution of lactose and sodium chloride on hygroscopicity‚ if any. It was found that HPMC SD and HPMC-LAC CP films were ‘moderately hygroscopic’ whereas HPMC-NaCl CP films were ‘very hygroscopic’. The percentage moisture content and classification of each sample as per Callahan et al. (Callahan et al.‚ 1982; Murikipudi et al.‚ 2013) has been listed in Table 5. 4. Discussion In
