In this summary I will explain the different aspects‚ concerning health and ageing. These are aspects are population and ageing‚ social exclusion‚ quality of life‚ discrimination and ageing and health in gerneral. To start with the aspect of population and ageing‚ the main issue first of all‚ is that the numbers and proportion of older people in the population are growing because of decreasing birth rates and increasing life expectancy. In fact‚ ageing is one of the greatest social and economic

absorbance at 470 nm since it is known to keep an acidic solution throughout the entirety of the experiment. It was important to do this right at the beginning of the lab since the zeroed value of the acid was the calibration number for all of the other solutions. A total of seven solutions with different dilutions were used throughout the lab to conduct the equilibrium constant. The first step was adding 5 mL of 0.200 M Fe(NO3)3to each of the 5 test tubes. Once this was done‚ 0.00200 M NCS was added to

Procedure: The unknown carbonate is weighed and then dissolved in water. A solution of CaCl2 (calcium chloride) is added to the metal carbonate solution to precipitate the carbonate ions as CaCO3 (calcium carbonate). The precipitate is then filtered‚ dried

Title: Calculating the Atomic Mass of “Pennium” Purpose: The purpose of this lab is to calculate the atomic mass of “pennium” using pennies made before 1982 and pennies made 1982 or after. Hypothesis: The atomic mass of the pennium will be the average of the average masses of a pre-1982 penny and a post 1982 penny. Procedure: 1. Obtain a bag of pennies 2. Determine the total number of pennies in the bag. Record the value. 3. Sort the pennies by date into 2 piles. One pile should consist

Check-List for Laboratory Reports 1. Your lab report must be written by word processor or by hand. Note that if it is written by hand it is your responsibility to ensure that it is legible and written in ink. 2. You must attach a cover sheet that will be the front of the report that contains your name‚ student ID‚ rotation number‚ and the name of your TA. Your rotation number = 1 if you are in my tuesday class and your rotation number = 2 if you are in my wednesday class. Failing to provide
