How does Concentration affect the rate of reaction between Magnesium
and Hydrochloric acid?
Secondary resources:
Chemical reactions only occur when reacting particles collide with
each other, with sufficient energy to react, this is called the
collision theory. The minimum amount of energy required to cause this
reaction is called the Activation energy. There are four main factors
which affect the rate of reaction. The first factor is:
Temperature of reactants:
When the temperature increases the particles move around faster
(because they have more energy). Because the particles are moving
faster , they are more likely to collide. When the temperature is low,
the particles are slower and they also collide less. The temperature
drop lowers the rate of reaction.
Another factor is:
Concentration of the reactants:
Concentration effects the rate of reaction because if there is more of
a substance, that means there is more particles. If there is more
particles, there as an increase number of collisions and an increased
rate of reaction. If there is less of a substance, that means there is
less particles, therefore there will be less collisions and an
decrease in the rate of reaction.
Another factor is:
The use of a catalyst:
A catalyst is a substance which increases the rate of a chemical
reaction, without being used up in the progress. Catalysts are
specific, I.e. different reactions need different catalysts. A
catalyst lowers the amount of energy needed for a successful
collision, so more collisions will be successful and the reaction will
be faster . Also it provides a surface for the particles to attach to,
therefore increasing the chances in colliding and also increasing the
rate o...

... I could have also use distilled water or mineral water
because these types water are more pure than tap water and would have
given a better result. To improve my method I also could have used
berates to measure the acid accurately, which would have given me a
much better result. The factors that effected my results, that I
couldn’t control were temperature of water, room temperature and
because I carried out my investigation on different days so on the
different days the temperature will also be different. I could control
temperature by carrying out the experiment on the same day, so the
temperature will be the same. I think my results are very reliable I
can see a clear pattern that matches my research despite the errors.

...tries receiving the stream of refugees. The crisis is generating an avalanche of issues in all countries providing safety to refugees and still receiving more every day. Not only is the inundation of Syrian Refugees to countries such as Jordan, Lebanon, and Turkey taking a ruinous toll on the countries’ economies, but it is also causing a range of issues due to overcrowding such as lack of resources and shelter; and the spread of diseases among refugees and their hosts; the refugee crisis is also creating social tensions between refugees and those who are natural citizens of the refugees’ host countries. As the surge of refugees continues reach Syria’s neighboring countries, it is creating many challenges for refugee-aiding countries as they struggle to bear the weight of so many refugees at the same time that they strive to support their own nations’ citizens.
In Antony and Cleopatra, the Roman values of honor and bravery embody masculinity, while Egypt and the Orient symbolize feminine weakness and fragility. Caesar and Agrippa are depicted as reasonable, logical, and practical, especially in matters of strategy and war. Cleopatra and her servants and eunuchs are consistently referred to in terms of laziness, let...

What is beauty? People have always attempted to find, create, and pursue it. A quick checkout at the grocery store will reveal a plethora of magazines devoted purely to what they call beauty and the proper pursuit of it. Most have an idea of what they might personally define as beauty, but not as a general, sweeping definition. That which one might label ugly another might call absolutely stunning. Some find beauty in cats, others in dogs, just as some favor early morning mountain ranges over a sun setting over the plains. “Beauty is in the eye of the beholder” is the favorite adage quoted by many to explain for this discrepancy, but what does that quickly-spat out phrase even mean? In reality, while the adage is partially true, beauty is not relative or subject to our human whim - it is an ideal created and truly attained only by God, which as His children we are to reflect in love.
The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
Bloom, Harold, ed. Introduction. Modern Critical Interpretations: William Shakespeare's Antony and Cleopatra. New York: Chelsea House Publishers, 1988.
If a reactant is a solid, then breaking it up into smaller pieces (but keeping the mass the same) will increase its surface area. If there is a larger surface area the reacting particles will have more of an area to react with, therefore there will be more collisions. 4. A catalyst works by giving the reacting particles something to stick to where they can collide with each other, because they are all attracted to the catalyst there are going to be more collisions. A catalyst does not get used up in a reaction.
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.
What is beauty? I have heard this question many times. I have heard the judge ask the contestant at a beauty pageant on television. I have heard professors ask us students in thought-invoking classes. I have heard it inside my head, my own inner voice, asking myself at night when I am left alone and the deep questions start coming in. What is beauty? And how are we to criticize or judge if one possess beauty or not?
If they collide with sufficient energy, then they will react. The minimum amount of kinetic energy required for particles at the time of collision is called the activation energy and this theory is known as the?collision theory?. Reactions occur in all circumstances. Chemicals are always combining and breaking up. Reactants and products combine and break apart in all reactions.
Beauty, how do we define it? Why is beauty so important among us? These are some of the questions that will be discussed in this paper, leaving a clear understanding of what “beauty” is and the many qualities which define “beauty”. We are regularly challenged with “beauty”, trying to define what it is and what it’s supposed to be, who is and who is not, and what is and what is not?
There are so many different opinions on what beauty is. The idea of beauty is purely opinionated. Beauty is your own idea, skinny or thick, long hair or short hair, light skin or dark skin. How people define beauty is unique in many different ways everyone has a different opinion. No ones idea of beauty is the same. In society today it has become more materialistic based if you wear the latest designer or you have the newest pair of sneakers out and the true meaning of being beautiful has escaped our souls. Beauty is not just what we see on the outside it is so much deeper then what we see its what we also have to offer on the inside.Your intelligence is beauty your mind, body, and soul. Beauty is not a single image, but the active embodiment
Fundamentally, I disagree with this interpretation of the play. Indeed we do see the fall of the great Marc Antony but the play never actually depicts scenes of his rise to prominence. `Antony and Cleopatra' is renowned as one of the greatest love stories of all time and I align myself with this conception.
