The Speed Of Reaction. Essay

984 words - 4 pages

Method

Step 1 – Remove blazer and put goggles on for health and safety reasons.

Step 2 – Collect the following equipment –
Thermometer – to check the temperate
Conical flask – to hold acid
1 litre breaker – contain water
Measuring cylinders x2 50ml 25ml
Blanco – to weight out the marble chips
Marble chips CaCO3 – which react with Hydrochloric acid
Stopwatch – to time when the reaction starts
Delivery tube – to pass the air
Camp stand – to hold the equipment
Boson – it heats up the water
Tripod – to hold the beaker at a certain height that has the most heat
Ice – to cool down the water of a certain temperate
Test tube holder – so you don’t burn your hand and it is safe.

Step 3 – Set up all the equipment.

A- Clamp Stand. B- Measuring tube (25ml) C- Delivery tube
D- Conical flask E- Reaction “what’s happening” F- Thermometer
G- Beaker H- Boson I- Tripod
J- Water K- 1 litre beaker

Step 4- My partner weighed the marble chips on the Balance, the amount we used was 1g.

Step 5- I poured the Hydrochloric acid into the 50ml measuring tube, the amount we used was 40ml.

Step 6- I filled the measuring tube with water and put my thumb over the top and press hard so there was no air in it.

Step 7- I filled the large beaker up with water and placed it near the clamp stand.

Step 8- I used the measuring tube and turned it over and put it in the beaker which has water in it then made sure there was no air trapped in the measuring tube.

Step 9- Make sure the delivery tube is fitted so the air that been created by the marble goes in the tube and not in the air.

Step 10- pour the Hydrochloric into the Conical flask then put the marble chips in, when the reaction takes place start the timer and close the lid tightly so the air is being delivered correctly.

Step 11- Watch the measuring tube and wait till the bubbles or air reaches to a target then stop the timer and take notes of the time and record it in the table.

Heating the Hydrochloric above room temperature: Before taking step 10. Heat up the Hydrochloric and then keep checking the temperature by using the thermometer, when the temperature is right then take Step 10.

Cooling the Hydrochloric below room temperature: Before taking step 10, collect the ice and put it in a small beaker and use the test tube to put it in between the ice and keep checking the temperature by using the thermometer, when the is right then take step 10.


My Aim

I am going to investigate whether the temperature affects the speed of reaction.

Introduction

Collision Theory
In all reactions particles hit together. The atom must hit to make new particles. To this I must be able to increase the temperature so that the reaction becomes faster. Chemical reaction only happen when...

Is it Possible to Travel at the Speed of Light?

3982 words - 16 pages equal and opposite reaction (Redd). Therefore, using Einstein’s definition of mass, light has to have mass and can gain momentum. If light can go faster than the defined speed of light, then, still using Einstein’s theory, an object of mass should be able to reach the minimum speed of light. An object of mass theoretically would be able to move at the speed of light if it was being “attracted” to a certain place in the “fabric” of space-time by a

The Discovery of High-Speed Manned Flight and Mach

1181 words - 5 pages This report analyses and discusses the discovery of high-speed manned flight and ‘Mach’ - in particular research and aviation breakthroughs relating to the specified topics. High-speed speed flight is technically defined as ‘flight near, but below the speed of sound’ [1A]. This begins at an airspeed of around 250 mph, or 400 kph. Properties regarding the airflow around an object at low speed or below this threshold of 400 kph are relatively

High-Speed Rail and the Advancement of America

4420 words - 18 pages Along with hover boards and flying cars, high-speed rail is one of the most iconic futuristic technologies discussed today. With great success, European and Asian countries such as Germany, France, Japan and China have been enjoying bullet trains for decades. Japan has been a leading innovator of high-speed trains, and has currently developed a train capable of 315 mph (Shadbolt). This MagLev is revolutionizing public transport and changing

Measuring the Speed of Sound. Physical Science lab write-up

656 words - 3 pages The purpose of this lab is to determine the speed of sound in air by using different variations of tuning forks, a resonance water tube, and large beaker to figure out how many points of resonance could be found in the wavelength. Using the date collected, equations were used to find the value of the speed of sound in the laboratory by plugging in the accepted value of sound in air and the knowledge that sound travels two feet per second faster

Exploring the Effectiveness and Dangers of High Speed Police Pursuits

2895 words - 12 pages . It is first worth looking at the way a pursuit is defined, ‘Pursuit may be defined as an active attempt by a law enforcement officer on duty in a patrol car to apprehend one or more occupants of a moving motor vehicle, providing the driver of such a vehicle is aware of the attempt and is resisting apprehension by maintaining or increasing his speed or by ignoring the law enforcement officer’s attempt to stop him’ (May & Headley, 2008).

Germany Has Set The Speed And Agenda Of EU Enlarge

Therefore, the determination of the agenda and speed of enlargement is part of a broad and complex policy process where relevant national policy-makers, the Council and the Commission interacted. Germany, with strong interests in Eastern enlargement has only been one of those actors; but not the leader of the process. Albeit influential, it did not always lead the policymaking process, nor were its views always adopted by other

Rates Of reaction- The reaction between limestone and hydrochloric acid

873 words - 3 pages think this as all the particles of limestone will be roughly the same size, the particles have a larger surface area than cubed limestone, therefore it will react the quickest. If you were to use cubed limestone it wouldn't be fair as no cube will be exactly the same size. In conclusion to this experiment, 0.5M of acid was the best to use as it had the best measurable reaction time.EquipmentThe equipment we will be using during this experiment is

What led Ethan to matrimony with this woman in the first place? The answer is a reaction to a situation, not a proactive decision. Zeena had come to help Ethan care for his ailing mother, and “when he saw her preparing to go away, he was seized with an unreasoning

describe the light reaction of photosynthesis

745 words - 3 pages digestive tract secrete hormones like gastrin, secretin, and cholecystokinin which act as chemical messengers on the areas of the digestive tract to control the process of digestion. The presence of protein in the stomach stimulates the secretion of gastrin.Even more important, though, are the intrinsic (inside) nerves, which make up a very dense network embedded in the walls of the esophagus, stomach, small intestine, and colon. The intrinsic nerves are triggered to act when the walls of the hollow organs are stretched by food. They release many different substances that speed up or delay the movement of food and the production of juices by the digestive organs.

The Speed Of Light Essay

363 words - 2 pages The speed of light in a vacuum is exactly 299,792,458 m/s. In 1983 physicists agreed to define a metre using the speed of light, i.e. a metre is defined as the distance traveled by a ray of light in a vacuum in 1/299,792,458s. The speed of light reduces when it passes through matter. It is hardly slowed down by air, but the speed of light through glass is reduced to around 200 000 km/s. Less dense materials (like water or ice) reduce the speed

The Effect Of Traveling At The Speed Of Light

1056 words - 5 pages Can Superman really move or fly at the speed of light? Many people think having an object moving at the speed of light is impossible for mankind right now. They also believe that later on, in the 25th century perhaps, mankind can build something that will travel at the speed of light. Are they dreaming? Is it possible for an object to be moving at the speed of light? Many science fiction and fiction movies are saying that it is possible. However

Research Experiment To Determine The Speed Of Sound

1861 words - 7 pages results. The stopwatch is not the most accurate means of measuring such minute milliseconds of time and the result does heavily rely upon the reaction time of the person responsible for timing. This could be a large reason behind the 3m/s-1 difference between the results of this experiment and the approximate correct speed of sound. This being said, factors of the air such as density and bulk modulus were not taken into account when calculating the
