Recommended: Affect of concentration on rate of reaction

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 in small to large clumps forming calcium Carbonate
Chips, however left in it's formed state it is powder, a chalk like substance. I could use either forms of the Calcium Carbonate for the experiment. Hydrochloric Acid, is a clear, colourless to slightly …show more content…

Word Equation
=============
Calcium carbonate + Hydrochloric Acid ===> Calcium Chloride + Water +
Carbon Dioxide

Symbol Equation
===============
CaCO3 + 2 HCl ---> CaCl2 + H2O + CO2

Prediction

My prediction is that if the concentration of the acid increases there will be an increase in output of Carbon Dioxide from the reaction for example the highest concentration produce the most gas in the given time. I used a preliminary test to help in the prediction. I went and prepared marble chips and concentrated acid we tried the experiment, the results was clear that as in a few seconds it was almost finished.
When we used very dilute acid it took so long for it to react and the amount of bubbles were much less than the first one. By using the results I can make the prediction of that, the rate of reaction is affected by concentration.

Hypothesis

If the concentration of an acid increase than output of gas will also increase. When the acid has a high concentration that means in that solution, compared to a dilute one there are more particles available to react with therefore the amount of times they will collide with the each other is …show more content…

The concentration of the reactants solution
3. Temperature of experiment
4. Amount of time available for reaction
5. Amount of solid reactant
6. Amount of reactant solution

Particle size

The reaction between calcium carbonate and dilute hydrochloric acid is used to prepare CO2. Varying the size of the Calcium Carbonate can make the reaction produce more or less Carbon Dioxide in the time frame available. I could try using either lumps or powder and see which reaction would produce more gas. This would have to be kept the same to ensure that the surface area of the Solid reactant remains the same as a greater surface area produces more gas than a smaller one. I have decided to use marble chips as tests reveal that powder allows to much gas to be produced to obtain an accurate recording.

Concentration

Concentration is a very important factor in rates of reaction. The concentration of a solution can greatly effect a reaction this is because there will be more particles of the reactant to react with, which will increase the time taken for the reaction. If the concentration of an acid is increased, the rate of reaction will increase because the collision rate would be higher and the amount of
CO2 would be given out more quickly. This is why the concentration

    I chose to read and comment on Barbara Kiefer’s “Envisioning Experience: The Potential of Picture Books.” Kiefer’s main point in writing this essay was to get the message across that children enjoy picture books that allow them to identify and make connections with the characters or the plots, and that while reading and analyzing the pictures, they gain a better sense of aesthetics and how to interpret them.

  • Hitler: The Rise Of The Life Of Adolf Hitler

    Hitler was originally born in Austria, although felt great pride for the German people and decided to join the German military during World War I. During the war, hitler was hit with mustard gas and was temporarily blinded. During this time Hitler heard of Germany's surrender through radio, eventually regaining his full sight back. Germany was the world's scapegoat after the war and was burdened with paying for all of the damages and became a laughing stock. Hitler swore to bring Germany from the ashes by planning a rebelion. As good as this looked on paper, it failed, and earned Hitler five years in prizen. While incarcerated, Hitler clearly voiced his oppinions for Germany in his book he wrote in prizen entitled Mein Kompf. The book became a smashing success and rewarded him with fame and a reduced sentence of only a few months.

    It has always been amazing to realize how well the literature I read as a child has stayed with me through the years. It takes an exceptional writer to compose a narrative that maintains a storyline on the same level of a child's understanding; it takes everything short of a miracle to keep a child's interest. However, that undertaking has been accomplished by many skilled authors, and continues to be an area of growth in the literary world. Only this year the New York Times has given the genre of children's literature the credit it deserves by creating a separate best-sellers list just for outstanding children's books. Yet, on another level, children's literature is not only for the young. I believe that the mark of a brilliant children's author is the age range of those who get pleasure from the stories; the wider the range, the better.

    Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Plan: In my experiment I will measure the rate of reaction between calcium carbonate and hydrochloric acid. The rate of the reaction is the speed that the reaction takes place so by measuring the rate I will measure the amount of time the reaction takes. Hydrochloric acid is a strong acid that is found in digestive juices in the stomach, it is also used for cleaning metals before they are coated. Calcium carbonate has a few forms including chalk and limestone the main use of these two materials is in the making of concrete, which is used for many things such as buildings. When you put calcium carbonate and hydrochloric acid together they react to form calcium chloride, carbon dioxide and water.

  • Children Literature Essay

    805 Words  | 2 Pages

    There are many different definitions of children’s literature and even varying definitions for literature and children! Before the nineteenth century, very few books were especially written for children. Since then, changing attitudes towards childhood and children’s development, along with the increased sophistication of print technology, have led to the development of children’s literature as a major industry. There is, however, no simple, straightforward definition of children’s literature that can be applied with equal validity at different times and in different contexts. Just as concepts of ‘child’, 'childhood’ and ‘literature’ have changed over time, so too have definitions of ‘children’s literature’. It is not a simple matter to define ‘childhood’ or ‘literature’. Some writers maintain that children’s literature differs from adult literature in degree only (Lukens, 1995); others (Lesnik- Oberstein, 1996) maintain that it differs in kind, that is, that the word ‘literature’ when used in the context of ‘children’s literature’ cannot necessarily be related in any straightforward way to the word ‘literature’ as used in other contexts. Thus, for example, Bottigheimer argues that children’s literature is “an important system of its own”. To complicate matters further, there are those who maintain that to be included in the category of ‘children’s literature’, writing must be of ‘good quality’. Thus, for example, Hillman would exclude from the category of ‘children’s literature’, writing that is “stodgy,” “too predictable,” or “too illogical.” Precisely how one determines whether a work meets these extremely vague criteria largely remains an open question.

    Peter hunt’s ‘Instruction and Delight’ provides a starting point for the study of children’s literature, challenging assumptions made about writing for children and they are trivial, fast and easy. Children’s literature is a conservative and reading it just to escape from the harsh realities of adulthood. It’s probably the most exciting for all literary studies, and a wide range of texts, from novels and stories to picture books , and from oral forms to multimedia and the internet , so it presents a major challenge and can be considered for many reasons. It is important because it is integrated into the cultural, educational and social thinking for the success of the publishing and media, and it is important to our personal development. Things that may seem simple at fist, how children understand the texts, how these differ from the

    Literature has been part of society since pen met paper. It has recorded history, retold fables, and entertained adults for centuries. Literature intended for children, however, is a recent development. Though children’s literature is young, the texts can be separated into two categories by age. The exact splitting point is debatable, but as technology revolutionized in the mid-twentieth century is the dividing point between classic and contemporary. Today’s children’s literature is extraordinarily different from the classics that it evolved from, but yet as classic was transformed into modern, the literature kept many common features.

Ironically, although social media sites boast their ability to connect people, they mainly separate society even more as people become isolated behind their screens. Social media is damaging to a person’s life because it can lower self-esteem, isolate people from real relationships, and cause privacy concerns as marketers, employers, and school officials can view information posted online.

    Facebook can keep you up to date on what is going on around you and around the world. Facebook, along with other social networking sites replace the normal face to face conversations and changes the way we interact with others. One common question that has always been asked when concerning social networking is, “Does it have an affect on one 's psychological well being?” There have been many studies that show that there are both positive and negative effects of Facebook. “Internet causes people to cut off from social interactions by communicating via a socially impoverished medium. The more individuals use FB, the less satisfied they feel about life (Chan 276).” The first study in this article is where they show the relationship between Facebook and how much people use it and how it correlates with their psychological well being. The second study talks about the good and the bad when it comes to Facebook. The third study talks about the empathetic social skills and how it effect those who use Facebook. Then goes on to describe what empathy means, which means the ability to share and understand people and their feelings. And empathy is a good a basis for for good social skills.
