Using sensors fitted in recent smartphones. The app can gather data about temperature. Pressure. Light intensity and humidity in any given location. Smartphones create a wide network of tine, mobile weather stations, offering real-time weather information for a variety of locations throughout the globe [6]. Crowdsourcing apps are changing everything from the way we travel, to the way we work, to the way we gather information. Fig. 1[3] represents the areas

Everybody makes mistakes and we are all human beings. We learn from the mistakes we make and the mistakes stay between us. When it comes to famous people, everything they do it monitored and judged by millions of people. This means that everything they do affects the world and the way they see things. There are many people who look up to celebrities and see them as role models. Celebrities are not good role models because they don’t use their social media the right way, they give out the impression

SPECIFIC PURPOSE To persuade my audience to become organ donors as a mean to help stop the crime of organ trafficking. INTRODUCTION Pretend there is something you really want. Pretend it is something that you simply can’t live without. You’ll probably be picturing a mobile phone, an iPad, a car perhaps… something that you depend on in your daily lives, and had become, along the years, an important part of you that you just can’t let go off. Wang, a Chinese teenager isn’t that different;

Are people you are around getting rude.Because more and more people are getting rude and just careless.But do you know why they are getting rude or in other words getting careless.A reading stated that people are getting rude because of their phones.For example the way they use them and act with their phones.LIke the guy who was gabbing on his phone at a Star Wars movie because he thought he was not being rude.In my opinion people are getting rude because of their phones and the way they use their

ache, vomiting. Venigar contains a small percentage of ethanoic acid Ch3COOH. This practical aims to find out the concentration of the of the vinegar against a standard solution of sodium hydroxide soloution of concentration 0.1 mol dm3 through acid-base titration, the label on the bottle says 6%. The equation of the reaction between sodium hydroxide and ethanoic acid is as follows: CH3COOH + NaOH → CH3COONa + H2O We can measure the end point of titration process and we can

It is type of condensation reaction, which involve the condensation of acidic anhydride and aldehyde in the presence of weak base (i.e. Sodium and potassium salt of the acid or trimethylamine) to give unsaturated carboxylic acid.(Equation-1)[1].In 1968 Perkin described the very first example of such type condensation reaction, involve the synthesis of coumarin by condensing the sodium or potassium salt of salicylaldehyde with acetic anhydride (Equation-2)[2].Generally such type of reaction is only

Discussion: End point in this acid-base titration experiment refers to the point where the chemical reaction has reached its conclusion and no additional titrant should be added. The end point of this experiment can be obtained when the indicator used changes colour. For example colourless to light pink when phenolphthalein is used and red to orange and subsequently yellow when methyl orange is used. Equivalence point, also known as stoichiometric point in an acid-base titration refers to the point where

There is a lack of education and public information based around dental erosion and furthermore, there is generally widespread ignorance of the deleterious consequences of dental erosion; this is distinctly the issue with erosion due to fruit juices as they’re seen to be healthy. [1][2] Tooth enamel is the hardest substance in the human body and it helps us with things such as chewing and biting. Even though enamel is an extremely solid substance, it can still break, and unlike bone, it cannot repair

Introduction: The acid-base titration experiment is the use of a titrant, an analyte, and an indicator. Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change.1 The titrate is what is later released into a beaker or flask that is filled with the analyte and indicator. The color change happens because of the indicator

Introduction Buffer is a solution that resists a change in pH when bases or acid are added. Solutions that are acidic contain high concentrations of hydrogen ions (H+) and have pH values less than seven. Buffer usually consist of a weak acid, and its conjugate base or a weak base and its conjugate acid. The function of buffer is to resist the changes in hydrogen ion concentration as a result of internal and environmental factor. This buffer experiment is important so that we relies the important

to categorize acids and bases into different strengths, following a pH scale.  pH stands for “power of Hydrogen”, and is used as a scale in order to conclude whether or not a substance is acidic, basic or neutral.  The scale ranges from a pH of 0 to a pH of 14 (with a colour that corresponds with each pH value for colour changing indicators).  A substance is an acid if it has a pH level of pH 0 to pH 6.  A pH 7 is neutral, which means that it is neither an acid nor a base.  A pH of 8 to 14 means

pH is a determined value based on a defined scale. This scale ranges from 1-14. The lower the number is the more acidic the water is, and the higher the number the more basic it is. If water or a substance has a pH of 7, then it is considered neutral. Both, natural and man-made factors can change pH levels in water and other substances. If the pH levels in water are too high or too low, living things in the water will die. pH can also affect the solubility and toxicity of chemicals in the water

An article by Siggard-Anderson (2005) explains that “acid-base balance refers to the balance between input (intake and production) and output (elimination) of hydrogen ion” (p.4). The maintenance of acid-base balance during exercise is vital to performance. This is because exercise decreases muscle and blood pH. When exercising a build-up of lactic acid can occur in the muscles which when coupled with an increase in carbon dioxide will lower your body’s pH balance. In order for the human body to

All living organisms contain a certain amount of pH level. pH levels are that indicate whether a substance is acidic or basic. Acidic substances are substances that have pH level less 7 and basic substances are substances that have a pH level of greater than 7. Most living cell in the environment has a pH level of 7 which are considered to be a neutral environment. To maintain this neutral environment cells must buffer the pH level so they are not too acidic or basic (Edwards et al, 2011). Buffers
