Nitroglycerin breaks down after being pressurized or exposed to heat. The balanced equation for when nitroglycerin combusts is 2C3H5(NO3)3 <--> 6CO2 + 5H2O + 3N2 + O2. Sometimes, dynamite can be closely related to TNT, although they aren’t much alike at all. Nitroglycerin should only be worked on when the substance is a liquid. If it is not, the frozen or semi-frozen state of the product is quite dangerous to handle.
This leaves a positive charge on one material and a negative one on the other, the charge depends on the material. Electrically charged objects attract small objects placed near them. Positive and negative electrostatic charges are only ever produced by the movement of the negative electrons, positive charges do not move. A positive static charge is created when electrons move away, and cause negative charges to move away as well. The key point that allows photocopiers, powder paint and precipitators work, is the face that objects with the same charge repel each other, whereas objects with opposite charges are attracted to each other.
Nuclear fusion however is the reaction in which two or more nuclei combine together to form a new element with higher atomic number. The fusion of two nuclei with lower masses than iron generally releases energy, while the fusion of nuclei heavier than iron absorbs energy. This means that fusion generally occurs for lighter elements only, and likewise, that fission normally occurs only for heavier elements. For a nuclear fusion reaction to occur it is necessary to bring two nuclei so close that nuclear forces become active and glue the nuclei together. Nuclear forces are small-distance forces and have to act against the electrostatic forces where positively charged nuclei repel each other.
During the explosion not only are gases produced quickly, but they are also hot, and they expand rapidly, according to Charles’ Law, which states that as the temperature of enclosed gas increases, the volume increases, if the pressure is consistent(Antonis, K. 2010). The chemical reaction the firework puts off is when [a]toms, as well as molecules, come together to form larger molecules, and larger molecules break up(Trefil, 2014). The chemical reaction also depends on the color of the firework. How do Chemists make the colors for Fireworks? When scientists make the different colors, each color has its own element.
Due to the enormous amount of CFC’s used, leakages in spray cans, refrigerants as well as general use, the CFC gases were released into the atmosphere. As CFC’s were so inert they did not react in the troposphere and gradually made their way to the stratosphere. This is where the ultraviolet energy separated the C-Cl bonds and as a result Cl free radicals were formed which reacted with ozone under UV light and thus destroying he ozone layer. When the chlorine atoms reach the stratosphere they undergo photodissociation. The chlorine radicals rapidly
They changed because the molecules of hydrogen and helium were moving so fast that they eventually escaped the Earth. 14. Explain how the greenhouse effect works and how it relates to global warming. The greenhouse effect is when radiation at visible wavelengths passes freely through the atmosphere and is absorbed at the ground. The ground heats up and emits infrared radiation.
Beta decay occurs when the neutron to proton ratio is too great in the nucleus and causes instability. And gamma decay occurs when the nucleus has too much energy. 3. What is meant by nuclear fission? Nuclear fission is a nuclear reaction that produces a lot of energy, and occurs when the nucleus of an atom splits into two parts spontaneously or with the impact of another particle.
On top of this, the helium nucleus is clearly labeled and is shown containing two neutrons and two protons (which are also labeled using an “N” and a “+”). Similarly, my model of beta decay is labeled in the same manner as that of the alpha decay model. In beta decay, an unstable atom uses its natural tendency to become stable to “transform” one neutron into a proton. Subsequently, the new positive charge requires an electron to be released from the atom’s orbit. This process is shown clearly in my model due to the fact that it states that the atom gets the energy to carry out this process from the instability of itself.
Exposure to high levels of radioactive waste can cause birth defects, cancer, and death. We all need to be aware of these dangers that exist across the country. It is imperative that we rethink our visual communication effort for warning current and future generations of the imminent danger below. The comic strip is a great medium to get across a point to many levels of audiences. In this cartoon I attempt to send the message that nuclear power will kill everything, even innocent cockroaches.
As a child, we could not understand the magnificent miracle that takes place for a star to be born. Now we know stars initially form from clouds of dust and gas. The force of gravity makes the dust particles come spiraling in together. As they do, the gravitational energy converts into heat energy and the temperature rises. When the temperature gets high enough, hydrogen nuclei undergo nuclear fusion to form helium nuclei and give out massive amounts of heat and light.
