Investigating How the Concentration of Hydrochloric Acid Affects the Speed of the Reaction with Marble Chips Introduction ============ There are many factors that will affect the rate of reaction between hydrochloric acid and calcium carbonate. Some of them are as follows: * Temperature - If the temperature is higher, then the molecules in the solution have more energy, causing them to move around more which would mean they would react faster. * The surface area of the calcium
Investigation looking At the Speed of Reactions Introduction The aim of this experiment is to find out how a variable can affect the results from a scenario set up in scientific environment. The experiment is to see how a certain variable will affect the amount of Gas produced from a Calcium Carbonate and Hydrochloric Acid Reaction. The Science Calcium Carbonate is a generally white or colourless mineral that is translucent. When compressed or exposed to great heat the mineral binds together
the reaction between Hydrochloric acid and Calcium Carbonate Introduction Hydrochloric acid + Calcium Carbonate Calcium Chloride + Carbon Dioxide + Water 2HCl(aq) + CaCO3(s) CaCl2(aq) + CO2(g) + H20(l) In this experiment we will be investigating the variables that can affect the speed of reaction between hydrochloric acid and calcium carbonate. During this experiment carbon dioxide is produced. This is what we are going to use to record the speed of reaction, for the faster the reaction the
The Hydrochloric Acid, Sodium Thiosulphate Reaction Research: "Hydrochloric acid is a strong colourless acid formed when hydrogen chloride gas dissociates in water, used in industrial and laboratory processes. Hydrochloric acid is also produced in the stomach, where it initialises the digestion of proteins. Sodium thiosulphate is a white crystalline salt used as a fixer in photography and as a bleach."

Marble Chips Experiment Pilot Aim: To investigate how the concentration of hydrochloric acid affect the speed of reaction with marble chips. Prediction: I predict that the more hydrochloric acid there is the faster the chemical reaction. I also predict that the more dilute the acid is (the more water there is with the acid) the slower the chemical reaction. Hypothesis: I predicted what I did because the more concentrated the hydrochloric acid is the more energy there will be and
group I etc). Elements within the same group similar chemical properties but often show a systematic variation in extent or speed of reaction as the group is descended. For example all of the group one elements (the alkali metals) react vigorously with water to form water soluble alkalis with the subsequent production of hydrogen gas. However, the speed of reaction increases down the group (lithium only reacts relatively slowly with water but francium and rubidium are explosive in the
of the yeast will increase in speed as the temperature of the water increases. However, it may reach a peak, and slowly decline as the temperature increases further. My reason for the above prediction is that, anyone who has cooked, knows that yeast is supposed to respond in warm water, so I believe that the warmer the water, the more bubbles of CO² produced. Also, the oxygen produced in the initial stages of the experiment will allow the speed of reaction, of converting glucose to energy
Affects The Speed Of A Chemical Reaction Aim --- To investigate the effect of concentration of acid, in the reaction between dilute hydrochloric acid and magnesium ribbon. Preliminary Research -------------------- The rate of a chemical reaction is the measure of how fast the reaction takes place. In a reaction particles must collide and overcome the fixed amount of energy for the reaction to take place. This energy is called the activation energy. The rate of reaction depends
Introduction: A chemical reaction is a process in which one or more substances are converted into other substances (Brown et al. 2015). The speed of a chemical reaction is called the reaction rate (Brown et al. 2015). The reaction rate is the change in the concentration of reactants or products per unit of time (Brown et al. 2015). Sometimes it is possible to measure the rate of reaction by timing a change in appearance (Van Norman 1963). Activation energy is the least amount of energy needed to
Concentration's Effect on the Speed of Reaction Between Magnesium and Hydrochloric Acid Planning 1: The aim of this investigation is to find out the effect of acid concentration in the reaction between dilute hydrochloric acid and magnesium ribbon. The rate of a chemical reaction is a measure of how fast the reaction takes place. A high concentration of hydrochloric acid could mean a fast reaction whereas as a low concentration could mean a slow long reaction. I will be testing different
Rates of Reaction Reactions Reactions can only occur when two different particles come together. The theory for the way the reaction occurs is called The Collision Theory. The collision theory states that that the different particles need to collide with each other in order to react. However, they do not react if they collide without sufficient energy, and therefore the more energy a particle has, the more likely it is to react. The activation energy is the minimum amount of energy
Enzymes are catalysts which lower the activation energy of chemical reactions, thus making them occur more rapidly. Enzymes are in constant use because of their ability to increase the rate of the reaction without permanent alteration. Each enzyme has a different rate of reaction as well as a maximum speed; you can find this number by adding substrate into the concentration until the speed remains constant. The maximum velocity divided by two gives you the Km. In this experiment the efficacy of the
that studies the speed at which a chemical reaction occur and the factor that influence this speed. What is meant by the speed of a reaction is the rate at which the concentrations of reactants and products change within a time period. Some reactions occur almost instantaneously, while others take days or years. Chemical kinetics understanding I used in the process of designing drugs, controlling pollution and the processing of food. Most of the time chemical kinetics is used to speed or to increase
chemical reaction that happens when the tablet starts to dissolve in water. You’re probably wondering what makes up these tablets? Well, it is mainly citric acid, aspirin and sodium bicarbonate. The sodium bicarbonate dissolves into the water and when it does dissolve it splits apart into sodium and bicarbonate ions. The bicarbonate
Rugby players have to have a wide range of good fitness traits such as reaction times, strength, and speed and cardio vascular endurance. Some players will excel at certain things, a prop for example might have excellent strength and endurance but might be very slow and have horrible agility and a winger might be extremely fast and have amazing reaction time but have no body strength. Strength, speed and reaction time endurance are the three points I will be talking about in this report. Being strong
How concentration affects the rate of reaction between Hydrochloric Acid and Sodium Thiosulphate Chemistry Coursework How Concentration Affects a Reaction Aim: The aim of this experiment is to find out how concentration affects the rate of reaction between Hydrochloric Acid and Sodium Thiosulphate. Introduction: This experiment will be carried out by drawing a cross on a piece of paper and mixing hydrochloric acid and sodium thiosulphate together to see if the cross disappears. The concentration
Rates of Reaction Investigation Reactions happen when the reactant particles collide and turn into a product. Sodium and chlorine, when reacted, they give us a compound Sodium Chloride (salt). Chemical reactions can be very difficult to undo. When metal rust this is a slow reaction, however burning, this is very quick. A speed on which the reaction takes place is called and rate of reaction. There are many ways on which to speed up the reaction. The most common is to speed up the collision

peroxidase reacts to different set ambient conditions and finding the conditions that allow for maximum rates. Enzymes are used in this experiment to demonstrate the importance of certain environmental conditions since they affect the speed of an enzymatic reaction in order to carry out life. An extract from horseradish is used as the enzyme since it contains peroxidase which has a highly accessible active site. The experiment was administered by using a spectrometer as a tool to measure oxygen production
