Rate of reaction of Magnesium and HCL
In order to find a good set of results for this experiment I need to
decide what molars i am going to use, and also how i will make them.
Once i have found which molars i would like to use i will give
evidence of why i have chosen them, i will also decide which variables
are important to considerm e.g The Values of Mg, Volume of acid. I
also need to think about how i am going to measure the speed of the
reaction in order to get a table of reliable results.
Plan
· Equipment needed for experiment:
· Bowl
· Hcl
· 2 Measuring cylinders (1 big/1 small)
· Mg strips
· Flask
· Beaker
· Tube
· Stop clock
· Goggles
· Beehive shell
Step One
All of the above equipment must be gathered.
Step Two
The Beehive shell sould be placed in the centre inside the bowl, then
the bowl is to be filled up with water until the beehive shell is
covered.Then the big measuring cylinder is to be filled to the top
with water and then turned upside down onto the beehive shell.
Step Three
The tube should be placed directly over the hole in the beehive shell,
where the tube(which goes through the hole in the beehive shell and is
connected to the flask) is placed into the cylinder.
Step Four
Then the flask needs to be filled with 20 cm3 Hcl acid, the acid is
measured in a measuring tube and then poured in, once the flask is
filled the magnesium strip is to be placed inside. In order to get the
Magnesium strip as accurate as possible it is to be measured with a
ruler to the size in which desired.
Step 5
As soon as the magnesium strip touches the acid it starts to react, so
the plastic plug should be put on to the flask quickly, then start the
stopclock and record the amount of gas every 10 seconds. One person
should read the results at eye level to the tube, so they can get an
accurate reading, and another person should note down the times
whereas one keeps there eye on the time.
Things that will effect the rate of reaction
· Concentration of Hcl
· Surface area of Magnesium
· Temperature of reaction
· Catalyst
· Length of Magnesium
· Volume of Hcl
The concentration can be increased or decreased to effect the rate of
reaction. The higher the concentration, the more particles, therefore
a higher rate of reaction.
The surface area of magnesium can effect the rate of reaction. The
larger the surface area, the faster the reaction will be as the
The results of this experiment are shown in the compiled student data in Table 1 below.
Possible sources of error in this experiment include the inaccuracy of measurements, as correct measurements are vital for the experiment.
To continue the experiment further I can use a different source of light to test the intensity of light. For the food coloring experiment, I could use a different food color such as yellow or orange to test.
The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
I will not add a catalyst to my solution and I will not stir my solution. · I will use 25cm3 of hydrochloric acid. · I will use 1g of calcium carbonate.
The Effect of Concentration of Hydrochloric Acid on the Rate of Reaction with Magnesium Aim: To investigate the effect of concentration of hydrochloric acid on the rate of reaction with magnesium Prediction: As the concentration of the hydrochloric acid increases, so will the rate of reaction Hypothesis: In a reaction, particles of two different reactants react together to form a product. The reaction only takes place on account of two things, if the particles collide, and if the collision has enough 'activation energy'. The two reactant particles, in this case magnesium particles and hydrochloric acid particles, must collide with each other on the correct 'collision course'. If this does not occur then no chemical reaction will take place. The reaction must also have enough energy, this can be affected by temperature, the more heat the particles have the faster they move and so the more energy therefore more chance of successful collisions.
from 10cm to 50cm to make it easier to see the difference in a graph.
Brutus murdered Caesar for the good of Rome. Although he killed Caesar, he did not do it for himself, but for the entire society of Rome. Mark Antony, an enemy to Brutus, also thought that he was a hero. “This was the noblest Roman of them all / All the conspirators save only he / Did that they did in envy of Caesar / He only in a general honest thought” (V.v.74-77). Antony is saying that all the other conspirators killed Caesar because they despised Caesar. He was able to declare the truth regarding Brutus. Brutus, actuality loved Caesar, so he could not have done it for himself. Caesar and Brutus were extraordinary friends that would do what was best for each other. “Et, tu, Brute – then fall Caesar” (III.i.85). Caesar says this in astonishment of Brutus stabbing...
In Medea, a play by Euripides, Jason possesses many traits that lead to his downfall. After Medea assists Jason in his quest to get the Golden Fleece, killing her brother and disgracing her father and her native land in the process, Jason finds a new bride despite swearing an oath of fidelity to Medea. Medea is devastated when she finds out that Jason left her for another woman after two children and now wants to banish her. Medea plots revenge on Jason after he gives her one day to leave. Medea later acts peculiarly as a subservient woman to Jason who is oblivious to the evil that will be unleashed and lets the children remain in Corinth. The children later deliver a poisoned gown to Jason’s new bride that also kills the King of Corinth. Medea then kills the children. Later, she refuses to let Jason bury the bodies or say goodbye to the dead children he now loves so dearly. Jason is cursed with many catastrophic flaws that lead to his downfall and that of others around him.
...ars. Jason begins to question why Medea has killed their children. In the stage directions it is noted, “Medea appears above the roof, sitting in a chariot drawn by dragons” (Euripides 1316- 1319). Only gods and prophets could command such creatures in Greek mythology. This action signifies the character Medea freeing herself from the guilt of killing her children and emotionally impairing her husband. Only through purity can one achieve such divinity. This makes Medea’s rebellion divine. Medea’s actions are a proof of mythology as symbolic of rebellion.
Medea’s illegitimate marriage and the betrayal of Jason drive Medea to extreme revenge. Medea chooses to act with her immortal self and commit inhumane acts of murder rather than rationalize the outcomes of her actions. Medea see’s this option as her only resort as she has been banished and has nowhere to go, “stripped of her place”. To create sympathy for Medea, Euripides plays down Medea’s supernatural powers until the end of the play. Throughout the play Medea represents all characteristics found in individual women put together, including; love, passion, betrayal and revenge. Medea’s portrayal of human flaws creates empathetic emotions from the audience. The audience commiserates with Medea’s human flaws as they recognize them in themselves. Medea plays the major role in this play as she demonstrates many behavioral and psychological patterns unlike any of the other Greek women in the play; this draws the audience’s attention to Medea for sympathy and respect.
Rate of Reaction - Sodium Thiosulphate and Hydrochloric Acid. Aim Investigation, to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration. Introduction I must produce a piece of coursework investigating the rate of reaction, and the effect different changes have on them. The rate of reaction is the rate of loss of a reactant, or the rate of development of a product during a chemical reaction. It is measured by dividing 1 by the time taken for the reaction to take place.
The dramatic ending serves a purpose as he wants to point out the flaws for Greek marriage traditions. He revealed the sexism in Greek marriages with Jason and Medea. Jason was very domineering and also portrayed as the antagonist, thus making his wrongdoings very unforgiving. His justification of leaving Medea was unreasonable and only made his situation worse. Jason, once the hero, is satirized by Euripides. His actions are not seen as heroic, even if he thinks about the well being of his sons. Medea, on the other hand, can be sympathized at first by seen from suffering from the lost of her love to an unfair reason. Her erratic behavior was well justified, she had the right to grieve over everything she had lost. However, her act of revenge went out of hand. Her act of revenge was worse than Jason’s act of betrayal. Her revenge add a dramatic effect which was intended to send a message. Euripides brought up a taboo aspect of marriage and divorce in Medea to show the flaws in Greek belief. Marriages were not fair, as shown in Medea. The character Medea, was used to send message that there needs to be justice for
Investigating the Effects of Temperature on the Rate of Reaction between Magnesium and Hydrochloric Acid
Medea’s sentiments control her actions throughout this tragedy. If the reader has never experienced a heartbreak, one will now feel the exact same “hurt where affection runs deepest” as Medea. Jason’s deception sparked “fierce”, “anger,” and “rage” in Medea. Her passion for Jason soon transformed into hatred. Medea emotions were contradicting because Jason caused the “deepest wound.” The only way to hurt Jason like he hurt her was to kill the royal family and to kill their sons. This revenge was bitter tasting. It was bitter because her kids suffered at the hands of someone who was to care and love them. Imagined how much pain and heartache a mother had to suffer to kill her own born. She killed her sons for two reasons: one, she knew the only way to ensure that Jason’s legacy never continues is if she did the impeccable and for two so people will not wish death upon her sons. Medea pride and emotions caused her to commit those acts. She knew she had stopped a line of Jason’s from doing what he did to her to anyone
