Introduction: Molarity (M) is used to determine concentration. Molarity is found by dividing the number of moles of a solute by the volume of the solution in liters. Multiple series of solutions with different concentrations can be used by diluting the concentration. The dilution technique is: Number Moles Concentrated Solution = Number Moles Dilute Solution. An instrument called a spectrophotometer detects the amount of light that passes through the sample and the percent transmittance can be recorded

Oxygen (O) Human beings obtain this element from the air. It enters a person’s bloodstream through the lungs. The blood carries oxygen to the cells of the body. In the cells‚ oxygen combines with chemicals obtained from food. Energy produced during this process makes it possible for each cell to perform its function in the body. Also‚ oxygen atoms are present in water and water is essential to all life. It is present in many organic compounds. While oxygen is necessary for life‚ oxygen as ozone

In 2009‚ Google has created PiLab to improve people’s operation. PiLab initiated Project Oxygen to research the impact of managers on employees and methods to enhance management. Google’s problem now is how to implement the research to increase efficiency for management. There are three alternatives which are to study senior management and executives‚ providing guidance to team composition and to study the complete life cycle of managers. The criteria used to evaluate each alternative are whether

Life puts us in a different saturation that built and let us discover many things. Sometime we need to go through a certain experience‚ because we have to and it is designed for us. In fact‚ some of the tasks are easy to do‚ while others are hard for some of us. Even if it was simple‚ it might have some difficulties in it is simplest. From a personal experience‚ I noticed that there are things that are too difficult to handle. The small details that we get from undertaken something‚ placed in our

Analysis: The graph of oxygen uptake vs time taken to run 1.5 miles has a negative linear association. As oxygen uptake increases‚ the time taken to run 1.5 miles decreases. This is can be seen through the gradient which has a value of 0.1705. This means that as the oxygen uptake increases by 1 ml/kg the amount of time taken to run 1.5 miles tends to decrease by approximately 1.7 minutes. The graph has a moderate relationship because the data is scattered in a wide band along the line of best fit

list of items‚ both tangible and non tangible‚ that trees give us. First of all‚ as we all know‚ trees are the most important and the only natural source of oxygen in the atmosphere. Without oxygen[->0]‚ life is not possible on earth. Trees consume the carbon dioxide[->1] from the environment and give out oxygen which balances the amount of oxygen and carbon dioxide[->2] in the atmosphere. In addition to this‚ the wood that we obtain from trees is used in making paper‚ building houses‚ making furniture[->3]

waters‚ such as lakes and streams. Phosphates are essential to aquatic plant growth‚ but too much phosphate can lead to the growth of algae and results in an algae bloom. Too much algae can cause a decrease in the amount in dissolved oxygen in the water. Oxygen in water is affected in many different ways by phosphates Phosphorus is usually present in natural waters as phosphate(Mcwelsh and Raintree‚ 1998). Phosphates are present in fertilizers and laundry detergents and can enter the water from
