characteristics of a candle. Also the purpose was to find the remnants that the combustion of a candle leaves behind as gas. I learned that the candle that is burning releases a certain gas into the air. I also learned that limewater has a chemical reaction when exposed to that gas and turns red. Hypothesis: For this Lab‚ my hypothesis was that the candles are going from solid to gas because of a high and quick rise in temperature. Materials 1. Large birthday candles 2. Matches 3. One used disposable

Abstract In the following project we are discussing about distillation. The operation of the distillation is employed for the purification of liquids from non-volatile impurities. The liquid is heated to the vapor phase and then is collected and recondensed to give back the pure liquid .The non-volatile impurities are left behind in the flask. Here our main focus will be at the fractional distillation. It is the process in which we separate the different components of a mixture on the basis of the

After the Bhopal gas disaster in 1984‚ the Indian legislation governing safety and environment underwent significant changes.Specifically‚the factories Act was amended to assign the responsibility of the “occupier”‚who is legally responsible for the safety of the workplace and workers‚to the highest level of management in an organization. For a company this meant that one of the directors on the board had to be designated as “occupier”.The Environmental legislation also underwent changes ‚with the

The following is the relation between the adsorption or gaseous adsorbent at definite temperature and the pressure of the gas is the first equation. n>1 Where x/m is the adsorption per gram of adsorbent which is obtained be dividing the amount of adsorbate (x) by the weight of the adsorbent (m). The pressure of the gas is p‚ k and n are constants. This relation is called as the freundlich adsorption isotherm. As see the following diagram. The value

Cutting operations should never be performed without a C) fire watch in the area. 11. Before performing oxy fuel cutting on a cleaned container‚ fill the container with an inert gas or C) water and position the container to displace as much air as possible from inside the container. 12. Because of its instability‚ the acetylene gas used in oxyfuel cutting must remain at pressures less than B) 15 psi when in its gaseous form. 13. Acetylene cylinders in use should be opened no more than C) 1-1/2 turns

Brian Ngo 3rd hour Chemistry 05/01/17 Due Date: 05/03/17 KAAAABOOOMM B***H The tanker imploded due to the cold weather around the tanker and the amount of oxygen in the tanker. There are two laws that can possibly explain why the tanker imploded. One of the laws is Charles’‚ this law basically explains that there is a relationship between temperature and volume. When heat is added to a liquid volume and temperature increase‚ but in a molecular level the molecules move faster bouncing around in the

conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Hypothesis: If the gasses are correctly synthesized then there will be a clear reaction with the introduction of the flame‚ O2‚ CO2‚ Air‚ limewater‚ and Bromthymol indicator. Procedures: Step 1. I placed a small amount of Mossy Zn in the test tube and then added HCL. I used the rubber stopper and a pipet bulb to collect the Hydrogen gas synthesis. I filled the pipet bulb with water and

Interference with gas exchange Asthma is a common chronic inflammatory disease of the airways characterized by variable and recurring symptoms‚ reversible airflow obstruction‚ and bronchospasm. Common symptoms include wheezing‚ coughing‚ chest tightness‚ and shortness of breath. Asthma is thought to be caused by a combination of genetic and environmental factors. Its diagnosis is usually based on the pattern of symptoms‚ response to therapy over time. In severe cases hospitalization can be required
