Redox reaction is the theory behind the Daniell cell. During the reaction cycle, electrons can be transferred as useful electrical current from the corroding zinc to the copper through an electrically conducting direction. The theory employed in the battery & Volta battery of daniell is the same.
Electrochemcial Cell Demonstration Voltaic Cell: Zinc/Copper E° = 1.10 V. A standard cell comprising of two half-cells: zinc metal electrode in 1.0 M ZnSO4 solution, a copper metal electrode in a 1.0 M CuSO4 solution, and a connecting salt bridge. The electrodes are connected to a voltmeter.
The Daniell cell is a type of electrochemical cell invented in 1836 by John Frederic Daniell, a British chemist and meteorologist, and consists of a copper pot filled with a copper (II) sulfate solution, in which is immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode.
Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference, as a measurable and quantitative phenomenon, and identifiable chemical change, with the potential difference as an outcome of a particular chemical change, or vice versa.

The median is a measure of central tendency that represents the middle value of a dataset when it is arranged in order. One way to estimate the median of a dataset is by using a cumulative curve.
A cumulative curve, also known as a cumulative frequency curve, is a graph that shows the cumulative frequency of a dataset. The x-axis represents the values of the dataset, and the y-axis represents the cumulative frequency. To create a cumulative curve, you first need to arrange the data in order, and then calculate the cumulative frequency for each value.
To estimate the median using a cumulative curve, you need to find the value where the cumulative frequency is exactly half of the total frequency.
For example, if you have a dataset of 10 values with a total frequency of 20, the median would be the value where the cumulative frequency is 10 (half of 20). By looking at the cumulative curve, you can find the value that corresponds to a cumulative frequency of 10, which is your estimate of the median.
In practice, if you have a large dataset, it may be more practical to use a cumulative frequency table rather than a graph. And if you have a continuous dataset, you can use a cumulative density function (CDF) instead of a cumulative frequency.

The mole, symbol mol, is the unit of amount of substance in the International System of Units. The quantity amount of substance is a measure of how many elementary entities of a given substance are in an object or sample. The mole is defined as containing exactly 6.02214076×10²³ elementary entities.

Genetics is the study of genes and tries to explain what they are and how they work. Genes are how living organisms inherit features or traits from their ancestors; for example, children usually look like their parents because they have inherited their parents' genes. Genetics tries to identify which traits are inherited and to explain how these traits are passed from generation to generation

✍ The formal technique for finding the gradient of a tangent is known as Differentiation from First Principles. By taking two points on the curve that lie very closely together, the straight line between them will have approximately the same gradient as the tangent there.

Projectile motion is a form of motion experienced by an object or particle (a projectile) that is projected in a gravitational field, such as from Earth's surface, and moves along a curved path under the action of gravity only.
Introduction to economics
In mathematics, an integral assigns numbers to functions in a way that describes displacement, area, volume, and other concepts that arise by combining infinitesimal data. The process of finding integrals is called integration. Along with differentiation, integration is a fundamental, essential operation of calculus, and serves as a tool to solve problems in mathematics and physics involving the area of an arbitrary shape, the length of a curve, and the volume of a solid, among others.

In implicit differentiation, we differentiate each side of an equation with two variables (usually xx and yy) by treating one of the variables as a function of the other.
The derivative of the parametrically defined curve x=x(t) and y=y(t) can be calculated using the formula dydx=y′(t)x′(t). Using the derivative, we can find the equation of a tangent line to a parametric curve.
The periodic table, also known as the periodic table of the elements, is a tabular display of the chemical elements. It is widely used in chemistry, physics, and other sciences, and is generally seen as an icon of chemistry.
In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the cell and controls the substances that go into and out of the cell.

MODE
The mode is the value that appears most often in a set of data values. If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled.
MEDIAN
In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.
MEAN
There are several kinds of mean in mathematics, especially in statistics. Each mean serves to summarize a given group of data, often to better understand the overall value of a given data set. Wikipedia

From Wikipedia, A request for quotation (RfQ)/ letter of quotation is a business process in which a company or public entity requests a quote from a supplier for the purchase of specific products or services. RfQ generally means the same thing as Call for bids (CfB) and Invitation for bid (IfB).[1]
An RfQ typically involves more than the price per item. Information like payment terms, quality level per item or contract length may be requested during the bidding process.
To receive correct quotes, RfQs often include the specifications of the items/services to make sure all the suppliers are bidding on the same item/service. Logically, the more detailed the specifications, the more accurate the quote will be and comparable to the other suppliers. Another reason for being detailed in sending out an RfQ is that the specifications could be used as legal binding documentation for the suppliers.

The name of a monatomic cation is simply the name of the element followed by the word ion. Thus, Na+ is the sodium ion, Al3+ is the aluminum ion, Ca2+ is the calcium ion, and so forth.
When naming these cations or compounds containing these cations, it is necessary to specify their charge. Cations and anions combine to form ionic compounds. Ionic compounds are named with the cation first and the anion last. The same convention is used when writing their chemical formulas.
In science, a cation is an ion, or charged particle, with a positive charge. In other words, a cation has more protons than electrons. If you come across the word ion in a chemistry or physics class, cation and anion won't be far behind. An ion is a particle that has an electrical charge.
In standard atomic notation, the name of an element is presented in the form of a symbol with certain super- and sub-scripts. A standard atomic notation shows the symbol, atomic number, mass number and charge (in case of an ion) of the element simultaneously.
The term matter refers to anything that occupies space and has weight—in other words, that element the universe is made of. All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions.
An atom is the basic unit of a chemical element. A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the VIDEO. Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner
A ray of light is the path along which the lights travel. Rays are observable. They travel along the straight line in a similar homogeneous medium and are represented by straight lines with arrowheads. The arrowhead indicates the path of light. Consider a plane-mirror and a fixed incident ray of light reflecting from the surface at an angle θ. Before the mirror has rotated, the angle of incidence is θ as is the angle of reflection.
✍🏻
The light traveling in any one direction in a straight line is called a ray of light. A group of light rays given out from a source is called a beam of light.
A ray of light that is incident on to the surface of a plane-mirror is reflected with the angle of incidence equal to the angle of reflection. Suppose that the ray had continued, through the mirror, in a straight line it would make an angle θ with the surface of the mirror. The total angle between the straight-line path and the reflected ray is twice the angle of incidence. This is called the deviation of the light and measures the angle at which the light has strayed from its initial straight-line path
The principle of reversibility states that light follows the same path if the direction of light is reversed. The refractive index of light when it passes from the first medium to the second medium is the same as the refractive index of light when it goes from second medium to the first medium.
What is Reflection on a Plane Mirror? When the light rays get stroked on the flat mirror, they get reflected back. According to the laws of reflection, the angle of reflection is equal to the angle of incidence. Get more lessons at https://tebtalks.com/
