<span>Specular reflection, or the act of seeing ones self in the mirror, is an everyday part of science that we commonly use without much thought about it. This is basically a reflection of light off a reflective surface, the image does not scattered but is printed on the surface for you to see.
Though quantum mechanics may explain how a magnet works scientist really have no true understanding of why charged particles create magnetic fields when they are moved around.
The microwave oven is another form of everyday thing that casually uses science. The science behind it is called electromagnetic energy. Basically it operates on a micro frequency that passes nearly harmlessly through plastics, glass, ceramics, etc to stimulate the atoms in liquids and meats to a reaction point that cooks them. Of course these micro waves also over stimulate metals thus why metal in the microwave is very bad.</span>
Practically any process you can think of in this modern world is made possible and available because of some form of scientific discovery. For example, I am able to take online classes, like I am doing right now, on the internet because of the scientific discoveries that have been made in order to create the laptops, the internet, and the online software used for the schooling. In addition to that has been previously stated, daily medicine or vitamin supplements that I take every day are a result of science and scientific discoveries that have been done to prove they help keep people healthy. Another thing we do every day thanks to science is washing our hands with soap every day and after we use the bathroom. We do this because of our understanding of germs that have been formed thanks to the process of the scientific method and scientific discoveries.
The sum of each elementary step in a reaction mechanism must yield the overall reaction equation. From the rate law of the rate-determining step it must agree with the experimentally determined rate law. The rate-determining step is the slowest step in a reaction mechanism. Because it is the slowest, it determines the rate of the overall reaction.
The factors that affect the rate of a reaction are:
<em>nature of the reactant</em> - when reactants with different chemical composition are exposed to same conditions they would react differently. For instance, when an acid or base is added on litmus paper, blue litmus paper turns red in presence of acid while red litmus paper turns blue when base is added.
<em>surface area</em>- a compound with small pieces spread over a large area will react faster than a big lump of a compound occupying a small area.
<em>temperature of reaction</em>- reactants would react faster at high temperatures. this is because they have higher kinetic energy to collide with each other. Hence a plate of food on the table spoils faster than a plate of food in the fridge.
<em>concentration</em>- an increase in concentration leads to more molecules available to collide and form products. An example, when you add more of indicator in a solution, the color becomes more clear since more particles react to give more color.
<em>presence of a catalyst</em>- a catalyst lowers the activation energy, which means less energy is required to shift reaction in forward direction. In the presence of iron (Fe) a catalyst, nitrogen N₂ and hydrogen H₂ react to produce NH₃
