<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 vibration of which bond gives an IR absorption that distinguishes between the following two compounds? CH3 CH2 CH2 OH CH3 CH
liq [111]

Answer: 3500cm-1

Explanation: The -OH bond absorbs IR and vibrates at a characteristic and many times distinctive wave number of 3500cm-1. The -C=O would vibrate at 1700cm-1 though not clearly because -C-O bond typically vibrates around this point

A compound has the molecular formula
Anna [14]

Answer:

Well, this compound is an organic compound, that the solid state at room temperature is determined by the joints it has and the type, strength and location of the joints or bonds.

Solid bodies, on the other hand, are those that maintain constant shape and volume thanks to the great cohesion of their molecules. The solid phase is one of the four states of matter aggregation, together with the liquid, the gaseous and the plasma

Explanation:

Regarding that it has non-polar molecules, this will influence its solubility or what type of solvents may be diluted and in which not.

Apolar molecules are those molecules that are produced by the union between atoms that have the same electronegativity, so the forces with which the atoms that make up the molecule attract the electrons in the bond are the same, thus causing the cancellation of said forces.

In this molecule, each oxygen atom attracts the shared electrons towards itself with the same intensity but in the opposite direction, so that the attractive forces are canceled and the molecule does not convert, it becomes a dipole. Furthermore, they can be identified through the Lewis structure with free pairs, that is, if it has free pairs, it is polar and if it does not, it is apolar.

In order to take into account in relation to the organism or if not a good example, the lipid structures of our organism have polar and non-polar sides, these non-polar sides are in charge of challenging hydrophilicity, since the apolar part or not NEVER will have an affinity for water, therefore it will not dissolve in it, something similar would happen with this chemical compound that we are talking about.

This is why when having non-polar molecules we can say that we are dealing with a hydrophobic compound or that it does not dissolve in water.

how many liters of water are needed to prepare 756 g of CaCO3 for a 3.50 M solution? MM=100.1 grams/mole
Gelneren [198K]

The volume of water needed to prepare the solution given the data is 2.16 L

<h3>What is molarity? </h3>

This is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

<h3>How to determine the mole of CaCO₃</h3>
  • Mass of CaCO₃ = 756 g
  • Molar mass of CaCO₃ = 100.1 g/mol
  • Mole of CaCO₃ =?

Mole = mass / molar mass

Mole of CaCO₃ = 756 / 100.1

Mole of CaCO₃ = 7.55 moles

<h3>How to determine the volume </h3>
  • Mole of CaCO₃ = 7.55 moles
  • Molarity = 3.5 M
  • Volume = ?

Volume = mole / molarity

Volume = 7.55 / 3.5

Volume = 2.16 L
