Investigate how the concentration of hydrochloric acid effects the rate at which it reacts with calcium carbonate :: GCSE Chemistry Coursework Investigation

Investigate how the concentration of hydrochloric acid effects the rate at which it reacts with calcium carbonate Investigation Plan Aim === Investigate how increasing the concentration of the solution hydrochloric acid effects and alters the rate at which it reacts with marble chip, calcium carbonate. Rate of reaction is affected by six main factors * Temperature * Surface area of a solid * Concentration of a solution * Pressure of a gas * By using catalysts * Using biological catalysts called Enzymes As outlined above the rate of a reaction increases when temperature increases, the concentration of dissolved reactants increases, the pressure of gases increases, solid reactants are in smaller pieces and of greater surface area and also if a catalyst is used. For this experiment I have been asked to pay particular attention to the factor CONCENTRATION, and the ways in which it affects the rate at which a reaction takes place. We can measure the rate of reaction by measuring the time at which the products of the reaction are produced or the reactants used up and there are a few different ways of doing this such as: By measuring gas volume Here the marble chips and dilute hydrochloric acid are put in a conical flask. This is connected to a gas syringe, which collects and measures the volume of gas formed. At regular time intervals a measurement is then taken of the volume of gas collected. Another way to measure the volume of gas produced is to displace water from a measuring cylinder as per diagram below. We can also measure the rate of reaction by measuring mass loss here when a gas is lost the mass decreases, which can be measured by placing the flask on a balance. The last way is to note how long it takes for a precipitate to form such as in the chemical reaction "the thiosulphate reaction". I conducted a preliminary experiment and from this determined that the most reliable and accurate way to measure the release of carbon dioxide gas would be by using a measuring cylinder to see the displacement of water and therefore determining how much carbon dioxide has been produced. Hypothesis I predict that as time increases so will the amount of carbon dioxide produced however throughout the experiment the rate of reaction will slow because as time increases there will be less and less un-reacted particles present to take part in fruitful collisions and result in carbon dioxide water and calcium chloride being formed, this means that the time between fruitful collisions will increase because a particle will take longer to find another un-reacted particle with enough activation energy to collide and react with. I hypothesise that as the concentration of the hydrochloric acid

1. What development in motor cars led to the need to replace the block brake? What was the replacement? With the adoption of pneumatic rubber tyres for cars in 1895, the block brake became impractical and was replaced as an automobile brake, and was replaced by the contracting band brake. 2. Who invented the drum brake? In what year did this occur? In 1902 Louis Renault invented the internal expanding drum brake. 3. Why was the drum brake superior to its predecessors? First, the shoes are enclosed on the drum so the friction lining is away from water or dirt, so they last longer. The drum brake also exhibits servo-assistance, in both forward and reverse; the leading shoe exhibits servo assistance in forward travel, the trailing shoe in reverse travel. 4. Why are the disc brakes used extensively now? The disc brake offers better heat dissipation than the drum brake and also offers better weather performance as water is thrown off the disc by centrifugal force. 5. Why is asbestos still allowed in brake linings in Australia? Asbestos gave the break lining greater stability at higher temperatures, thus the linings are more resistant to break failure form the heat. 6. The coefficient of friction (Â µ) is ratio between what two values? The coefficient of friction is the ratio of the frictional force present and the normal reaction to the matting surfaces. Â µ=FFRN 7. What is the tensile stress in a brake cable of diameter 2 mm if the tensile force in the cable is 200N? 8. Draw a stress strain curve for mild steel; label the proportional limit, the upper and lower yield points and the UTS. . What is the difference between elastic and plastic deformation? 10. State Pascals principle. Why is it important to hydraulics? 11. What is steel? 12. What is the difference between austenite and ferrite? 13. What is pearlite? 14. What happens to the hardness of steel as the amount of cementite increases? 15. Describe what martensite is. 16. Why is manganese added to steels? 17. What effect will nickel have if added to a low alloy steel? 18. Why is molybdenum added to the nickel-chromium steels? 19. Why is Hadfield steel used for? What is different about its structure at room temperature as opposed to plain carbon steels? 20. There are three types of stainless steels available. List three and describe the uses of each? 21. Which stainless steel is non-magnetic? 22. What is the difference cast iron and steel? 23. Carbon appears in different forms in cast irons, how does it appear in white cast iron and grey cast iron? 24. Which type of grey cast iron is stronger, fine or course? 25. How do SG cast iron and CG cast iron differ? 26. Blackheart malleable cast iron has free carbon present in Whiteheart malleable cast iron? 27. Is free carbon present in Whiteheart malleable cast iron? 28. Why is copper added to break pads? 29. What type of resin is used to bind the break pad together? 30. Draw two stress strain diagrams, one showing high toughness, and one displaying high strength but a brittle failure. 31. What are the four hardness tests available? 32. Find the tension in the vertical and horizontal cables for the brake system shown. Slove this problem graphically then analytically.
