all having their own drawbacks. But‚ the one that will be focused upon in this analysis is hydrogen as a source of fuel‚ and the technology leading the way to making it a reality. This technology would affect everyone in one way or another if correctly used. So we must ask if this technology is beneficial to us‚ how it might hurt us‚ and whether it is worth pursuing from an ethical stance. Background: Hydrogen has already been under the micro scope for many years as an alternative fuel source to us

It also created solutions containing varying levels of concentrations and densities. Equations were used to figure the molecular weight of the sugar‚ and the number of moles of sugar in the volumetric flask. There was also an equation to figure the Molarity‚ as well. As a result of the experiment‚ I now have a better understanding of the density of a concentration‚ and what Molarity is .

Solutions and Their Concentrations 1. Molar Concentration or Molarity – Number of moles of solute in one Liter of solution or millimoles solute per milliliter of solution. 2. Analytical Molarity – Total number of moles of a solute‚ regardless of chemical state‚ in one liter of solution. It specifies a recipe for solution preparation. 3. Equilibrium Molarity – (Species Molarity) – The molar concentration of a particular species in a solution at equilibrium. 4. Percent Concentration a. weight

The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between

respiration and photosynthesis. Photosynthesis is performed by plant organisms and some bacteria‚ and cellular respiration is performed by all living organisms. These two processes are reliant on each other. Photosynthesis creates oxygen‚ which is used in cellular respiration. Cellular respiration in turn creates carbon dioxide‚ which is an important “ingredient” in the process of photosynthesis. Let’s take a closer look at what makes these processes so important to all living things. Photosynthesis is the

Rate of Osmosis vs Solute Concentration Introduction: In nature‚ the quest to reach equilibrium‚ or the state of rest or balance due to the equal action of opposing forces (http://www.dictionary.com). Osmosis and diffusion are two ways that cells reach this equilibrium‚ without exerting energy. Due to the unique nature of the phospholipid bilayer‚ small molecules can pass through the semipermeable membrane easily‚ through diffusion (https://www.biologycorner.com). Water‚ however‚ has a slightly more

Concentration Ratios in Manufacturing ECO 204 Principles of Microeconomics June 28‚ 2011 Industries go through a lot of changes to make themselves successful. There is so much competition that they have to keep up with the market. Using the concentration ratio which is the share of industry output in sales or employment accounted for by the top firms (Karl Case‚ Ray Fair‚ Sharon Oster 2009 p285). Porter explains that there are five forces that determine industry attractiveness

Introduction A chromosome is a minuscule threadlike part of the nucleus and a structured DNA in the form of genes carrying hereditary information (Bridges‚ 1938). Endomitosis is the process of mitosis of chromosomes without undergoing nuclear or cellular division to increase cell volume. This results in a single nucleus having many copies of a single chromosome (Painter & Reindorp‚ 1940). In this experiment‚ Drosophila melanogaster is reared in specific conditions and its salivary gland extracted

Through this experiment‚ Egeria densa was observed using a microscope. The task was to observe and identify the different types of cell‚ cytoplasmic streaming‚ and plasmolysis of Egeria densa. First‚ the microscope was examined and investigated to master the use of the equipment. A microscope slide grid which was on the slide glass was required to be seen clearly using 4x‚ 10x and 30x. During the latter part of the experiment‚ the Egeria densa was observed using the microscope to understand the
