How Much Gas is Produced? Julie Dang June 23‚ 2013 Purpose The Company ABC Chemical has asked our group to investigate the gas production from a number of various chemical reactions. The company would like us to measure the amount of product we get when we measure the amount of gas from two reactions. We will then compare our data to the predicted amount which will we will calculate based of the Law of conservation of Mass and Ideal Gas Laws. Methods Materials Thermometer CaCO3
Free Gas Pressure Ideal gas law
Purpose To explore transport of materials in three semi-permeable membranes: dialysis tubing‚ eggs‚ and onion cells. Background Information 1. Diffusion is the movement of solutes from high to low concentration. Osmosis is the movement of water from low to high concentration. Both refer to movement in/out of a cell‚ but osmosis refers specifically to water. 2. Isotonic‚ hypertonic‚ and hypotonic all refer to the comparison of concentrations of solutes in verses out of the cell. Isotonic is

The Floating Egg Problem Introduction: This experiment was constructed to aid in the practice of using the volumetric system and the glassware that determines volume. Volumetric glassware contains an accurate amount of liquid and also measures the volume accurately. Density is a measure of how much matter takes up a certain amount of space or volume. The more matter you can pack into a certain space‚ the denser it is. Although we often confused the two‚ density and weight are actually two

Ammonia and Its Salts 1. Ammonia‚ NH3 is a very important compound in industry. 2. The main uses of ammonia: a) To manufacture nitrogenous fertilizers such as ammonium sulphate‚ ammonium nitrate and urea b) The liquid form is used as a cooling agent (refrigerant) in refrigerators c) As a raw material for the manufacture of nitric acid in the Ostwald process d) To be converted into nitric acid used for making explosives e) As an alkali to prevent the coagulation of latex

How does the relationship between salt concentration effect osmosis in the aquatic plant Elodea? Quantitative data From observing the cells under a microscope‚ we see that they are continuously moving and therefore are alive. We have observed that when the cells are in the 10% sodium chloride‚ the chloroplasts are positioned to the sides of the cell wall and the cytoplasm is more expanded. Cells in the distilled water are slightly smaller than the cells in the sodium chloride solution and

Matthew 5:13-14 How does being salt and light relate to the Beatitudes? The Beatitudes define acts of kindness and depict the qualities needed for entry into and life inside the Kingdom of God. The residents of the Kingdom exhibit these specific qualities. At the point when and as they do‚ they are salt and light. As a blessed people and the children of God‚ we are salt and light in the work environment‚ in our homes‚ and in our country. In lowliness and obedience to God‚ we work for socially

I. Purpose The purpose of this lab was to see how an egg would react through a chemical reaction if it were to be added with an acid and a base. II. Materials 1 egg 400 mL beaker Citric acid Baking Soda Water Food coloring (optional) Stirring rod III. Procedure 1. Crack open and separate egg by pouring yolk back and forth between egg shell halves with the whites in the beaker 2. Add 5.0 grams (1 tsp) of citric acid 3. Add 5.0 grams ( 1 tsp) of baking soda 4. Put 2-3 drops of

Question 1 a) i If Johns takes $10‚000 and deposit in the banking system‚ the total amount of of deposits in the banking system increase by $100‚000 ( $10‚000 x 10)‚ because the reserve ratio is of 10% which mean the money multiplier is 1/R= 1/0.10 = 10. ii As bank deposits are part of the money supply‚ so John deposited $10‚000 but the bank is required to keep a ratio of 10% or $10‚000. Taking in consideration i above by using the money multiplier the bank is allowed to make a maximum of $90‚000

The documentary film “The Take” or “La Toma” shows Argentina in the midst and the aftermath of an economic collapse as unemployment skyrockets and almost half the country plummets below the poverty level. In the beginning of the documentary‚ shows an emerging economy transitioning into first world status comparing it to Australia or Canada where Argentina was considered the most prosperous middle-class in Latin America. However‚ the country took a turn for the worst under the presidential reign of

Objective: To observe the effects of osmosis on eggs placed in vinegar (5% acetic acid)‚ syrup (60% sugar solution)‚ and water (100% distilled). Hypothesis: Hypothesis #1: It was hypothesised that the egg would gain 59 grams of mass after soaking in vinegar for 24 hours. Hypothesis #2: It was hypothesised that the egg would become larger when soaked in syrup than it once was due to the hypotonic environment. Hypothesis #3: It was hypothesised that the egg would soak in water for 72 hours‚ losing mass
