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.

As the temperature increases, the movements of molecules also increase. This is the kinetic theory. When the temperature is increased the particles gain more energy and therefore move around faster. This gives the particles more of a chance with other particles and with more force.
It is important however to note that the NH4 and K ions are still in
The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
The number and strength of collisions is increased so that the reaction can happen faster than it should. If the particles have more energy then more particles will be able to react to it. Solid reactants like marble chips are affected by surface area. The larger the surface area, the more collisions that will take place.
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?
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...
...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.
• An increase in the temperature of the system will increase the rate of reaction. Again, using the Maxwell-Boltzmann distribution diagram, we can see how the temperature affects the reaction rate by seeing that an increase in temperature increases the average amount of energy of the reacting particles, thus giving more particles sufficient energy to react.
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.
There are five factors which affect the rate of a reaction, according to the collision theory of reacting particles: temperature, concentration (of solution), pressure (in gases), surface area (of solid reactants), and catalysts. I have chosen to investigate the effect of concentration on the rate of reaction. This is because it is the most practical way to investigate. Dealing with temperatures is a difficult task, especially when we have to keep constant high temperatures. Secondly, the rate equation and the constant k changes when the temperature of the reaction changes.

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?
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.
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.
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
