<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.

<h3>What is a Chemical Reaction ?</h3>

Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products.

Substances are either chemical elements or compounds.

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

Chemical reactions are an integral part of technology, of culture, and indeed of life itself.

The product that is formed is shown in the figure , Option A is the correct answer , and the highlighted carbons shown corresponds to the carbons from diethyl malonate.

Pure metals possess few important physical and metallic properties, such as melting point, boiling point, density, specific gravity, high malleability, ductility, and heat and electrical conductivity. These properties can be modified and enhanced by alloying it with some other metal or nonmetal, according to the need.

Alloys are made to:

Enhance the hardness of a metal: An alloy is harder than its components. Pure metals are generally soft. The hardness of a metal can be enhanced by alloying it with another metal or nonmetal.

Lower the melting point: Pure metals have a high melting point. The melting point lowers when pure metals are alloyed with other metals or nonmetals. This makes the metals easily fusible. This property is utilized to make useful alloys called solders.

Enhance tensile strength: Alloy formation increases the tensile strength of the parent metal.

Enhance corrosion resistance: Alloys are more resistant to corrosion than pure metals. Metals in pure form are chemically reactive and can be easily corroded by the surrounding atmospheric gases and moisture. Alloying a metal increases the inertness of the metal, which, in turn, increases corrosion resistance.

Modify color: The color of pure metal can be modified by alloying it with other metals or nonmetals containing suitable color pigments.

Provide better castability: One of the most essential requirements of getting good castings is the expansion of the metal on solidification. Pure molten metals undergo contraction on solidification. Metals need to be alloyed to obtain good castings because alloys

In the Penny Lab that we ran, what is the independent variable? Question 1 options: the soap the number of water drops the penny
motikmotik

Answer:

I'd say it's the number of water drops.

Explanation:

The number of water drops is what you're controlling or purposely controlling and that answer choice makes the most sense out of the other answer choices. So I'd say it's "The Number of Water Drops."

Prove that the liquid pressure is directly proportional to the depth of the liquid?​
Free_Kalibri [48]

Explanation:

Pressure and depth have a directly proportional relationship. This is due to the greater column of water that pushes down on an object submersed.. so the deeper the liquid level the higher the pressure of the liquid.
