theory that it exists and have done some really crazy things ,such as threaten suicide, because they are so disturbed about the planet. Maybe that is why it is also called the “doomsday planet”. Planet X has also been named Nibiru and is considered the twelfth planet. The name Nibiru came from a book written by Zecharia Sitchin. The book told about a twelfth planet with an oblong orbit. It was supposed to get near the earth every 3600 years. The book was called The Twelfth Planet. The book told the
The question of extraterrestrial life has perplexed scholars for many years. With so many reports of UFO’s and abductions, what is the truth of the matter? I have read many of Zecharia Sitchin’s books about extraterrestrials visiting Earth in the distant past. He collects his information from ancient clay tablets written in cuneiform, the bible, and many archeological sites from all over the world. In his series of books called, The Earth Chronicles, Mr. Sitchin has concluded that aliens came to
speculation toward the origin of biotic forms, what was present at the formation of the earth that could result in inorganic, then organic, and later biotic creatures? Early atmospheric conditions have been theorized to be present due to planetesimal collisions releasing gases present in the Earth, after the initial atmosphere of Hydrogen and Helium escaped Earth’s gravity assisted by heat energy. The earlier atmosphere is believed to have consisted mainly of carbon, hydrogen, nitrogen, and oxygen (bonded
Electrical Resistance Electrical resistance is a property of an electrical circuit that opposes the flow of current. Resistance involves collisions of the current-carrying charged particles with fixed particles that make up the structure of the conductor. Resistance is often considered as localized in such devices as lamps, heaters and resistors in which it predominates, although it is a characteristic of every part of a circuit, including connecting wires and electric transmission lines
more spread out, this results in fewer collisions, so therefore there will be a result of fewer successful collisions. Which will then make the reaction taking place speed go slow, so there would be a graph with a rather slow reaction taking place. If I was to do the experiment with a high concentration the particles are crowed close together and therefore it would collide with each other more often, which will give me a result of successful collisions. So for my experiment I predict that the
this there is a greater chance of collisions with the electrons and they are impeded more, therefore less charge is passed by the electrons and the resulting current is reduced. This means while conducting the experiment the temperature of the wire must be kept constant to maintain a safe and fair test. Cross-sectional area/ width: If the cross sectional area is increased there is more space for the electrons to move freely making less collisions so more current will pass through making
increased then the particles will move faster. This leads to more collisions. In addition, particles have more kinetic energy, so more collisions will lead to a reaction. *The effect of the surface area on the rate of reaction is, when one of the reactants is a solid, the reaction must take place on the surface of the solid. By breaking the solid into smaller pieces, the surface area is increased, giving a greater area for collisions to take place and so causing an increase in the rate of reaction
because it will cause more collisions between the atoms and the electrons. The increase in collisions would obviously cause the resistance to rise. Secondly, the length of the wire is a factor. The longer the wire, the longer it will take electrons to get to the end of the wire. This is because there will be more collisions between electrons and atoms. So, the length of the wire should be directly measured to the resistance if not then there will be fewer collisions. This would be very easy
Resistance The electrical resistance of a material is its opposition to the flow of electric current (slowing the flow of electrons down). Resistance occurs when the electrons travelling along the wire collide with the atoms of the wire. These collisions slow down the flow of electrons causing resistance. Resistance is a measure of how hard it is to move the electrons through the wire. A current is the rate of the flow of charge (electrons) and the resistance controls the amount of current
speed up the collision between the particles. The more collisions per second the faster the reaction will be. To speed up chemical reactions; INCREASE THE TEMPRETURE Reactant particles hit each other harder because they have more energy in them. Also the temperature increase makes the particles grow more so the frequency of collisions increases. [IMAGE] [IMAGE] Fewer particles energised so fewer collisions More particles energised so there are more collisions. [IMAGE][IMAGE][IMAGE][IMAGE]
of the wire Background Factors: i. Temperature : If the wire is heated up the atoms in the wire will start to vibrate because of their increase in energy. This causes more collisions between the electrons and the atoms as the atoms are moving into the path of the electrons. This increase in collisions means that there will be an increase in resistance. ii. Material : The type of material will affect the amount of free electrons which are able to flow through the wire. The number
concentration is increased then the number of particles in the solution increases. If this happens then the number of collisions will increase, and therefore the number of successful collisions will increase. This is because the more particles of HCl, then there are more collisions; therefore the collision frequency is higher. Therefore increasing the successful collision frequency. II.The same person with the stopwatch: - The person using the stopwatch has to stay the same because each
Reaction Aim: To find out how different concentrations change the rate of reaction Theory: In this experiment the collision theory is in use. It means that when the concentrates solutions of hydrochloric acid is use, more particles are found in the same space, which means they are more likely to collide with each other. the more the concentrated the solution, the more of the collisions with the particles, which increases the rate of reaction. Prediction: As the concentration of the solution
In society, any accidents are perceived as negative outcomes illustrate a terrible ending that has taken place but in reality it can be perceived as something positive in the long run. By obstructing the 2005 Camaro and the three teens, it occurred that no one was injured and everything was calm. Accident by Dave Egger represents how a bad decision becomes a point of conflict and symbolism within the theme of the story. As a result, in making wise choices, you are able to receive positive and negative
can be used to explain the factors affecting the rates of reaction, this is an extension to the kinetic theory called the collision theory. The collision theory says that Chemical reactions occur when particles of the reactants collide. They must collide with a certain minimum energy, called the activation energy. To summarise, the requirements for an effective collision (for a chemical reaction to occur): The reactants must collide with each other, The molecules must have sufficient energy
successful collisions. If you increase the concentration, then that means that there are more particles in the same volume to react. Therefore, there will be more successful collisions per second. If there are more successful reactions, therefore the rate is also increased. When there is a high concentration, the reactants have more successful collisions per second; therefore the rate of reaction is quicker. When there is a low concentration, The reactants have less successful collisions per second
The variables I plan to control 1. Surface area: The surface area of each marble chip should be kept relatively the same because due to collision theory if more surface area is available the number of particles of solid reactant available for collision will increase. Therefore more collisions can occur, and it is likely there will be more collisions with sufficient energy to successfully lead to a reaction. I might not be able to keep the surface area of my marble chips exactly the same
H2SO4 à H + ZnSO4 This reaction is catalysed by Copper sulphate (CuSO4) Ionic Equation - Cancel Spectator ion (SO42-) Zn + 2H+ à Zn2+ + H2 For this reaction to work there must be hard collisions between the zinc and the hydrogen ions (acidity ion) from the acid, The faster the harder and the more often the collisions happen so I predict the more catalyst the faster the reaction. Planning Safety * Sulphuric acid at 2M is a corrosive substance but diluted to 1M it is an Irritant, so wear a Lab coat
collide in order to react, and the have to collide hard enough as well. This is called the collision theory. When the temperature is increased the particles all move quicker. If they are moving quicker then they are going to have more collisions. Higher temperature also increases the energy of the collisions, because it makes all the particles move faster. Increasing the temperature only causes faster collisions. Reactions only happen if the particles collide with enough energy. At a higher temperature
true because they all link to the collision theory of particles colliding with enough energy to make a reaction. It is based on the idea that for a chemical reaction to take place, the reacting particles have to hit each other hard enough to break or form new bonds. This is called a successful collision. When particles get stimulated or increased in number, the reaction will increase in rate because faster collisions will take place making more successful collisions. This diagram shows five solutions
