of involvement of the LGBTQ community in media and the stereotypical depictions of queer sexuality leads us to believe media has become a negative platform. This matter is perceived in the episode “Lesbian Request Denied” from the television series Orange Is The New Black as it captures Lavern Cox’s struggle in prison as a transgender individual. As I considered the impact of cultural gender definitions on transgender people‚ I further wanted to discover

Content Theory of Motivation Maslow’s Hierarchy of Needs Maslow believed that the importance of human needs depended on what they already had. He believed that the hierarchy started with physiological needs and once those needs were fulfilled‚ then safety needs and security would be sought. Once the person felt safe and secure they would then be motivated by the need to have love and friendship. When those social needs were achieved the person would then look to fulfil their esteem needs

Conclusion Guidelines A good conclusion should contain all of the following parts a) You should state what experiment was performed‚ and show any necessary reaction schemes. The reaction schemes should include molecular weights and any other important physical data for the reagents and products. Ex. Cyclohexanol was oxidized to cyclohexanone using sodium dichromate in the presence of sulfuric acid. * Note: you can download a free version of a structure editor from ACD labs‚ the PC version is called

loss from the hot water from combining it with the cold water. As discussed in a page titled Heat Capacity2‚ the heat capacity is defined as the amount of heat it takes to raise the temperature of a substance by one degree (in this case C). In the experiment performed in lab‚ the heat capacity of the calorimeters was calculated by subtracting the heat gain from the heat loss and then dividing that by the difference in the temperatures between cold water and the combination of the hot and cold water

Discussion: First of all‚ rinse all the apparatus that being used in the experiment with hydrochloric acid (HCL) then followed with distilled water (H₂O). Then‚ prepared the saturated calcium hydroxide (Ca (OH) ₂) solution into a filter funnel and filter paper over a second conical flask. Pour 100.00mL of saturated Ca (OH)₂ solution into a beaker and pour the solution through the filter paper by flowing the solution through a glass rod. After that‚ use a thermometer to measure the temperature of

Economics Boost Juice Case study Boost juice is currently experiencing economies of scale 3 reasons for Boost Juice experiencing economies of scale 1 – Purchasing inputs and raw materials in bulk • Buying in bulk means that the average cost of each unit of raw material is cheaper than if each unit was bought individually • In one year alone‚ Boost juice goes through more than 35 tonnes of mangos and you still have all of the other range of fruits that are bought. Therefore buying

ETHERS Classification of Ethers: Symmetrical ethers – two groups attached to O are identical Ex. CH3CH2OCH2CH3 – diethyl ether Unsymmetrical ethers – two groups attached to O are not identical Ex. CH3CH2OCH3 – ethyl methyl ether Physical Properties of Ethers: Ethers have much lower boiling points compared to alcohols of comparable MWs. BPs of ethers increases with increasing MW. BPs of isomeric ethers increase with increasing alkyl chain length. BPs of ethers are about the
