Gas laws and ideal gas equation

Gas laws describe the behavior of gases under different conditions, such as temperature, pressure, and volume. There are several gas laws, including Boyle’s law, Charles’s law, Gay-Lussac’s law, and the combined gas law, that relate these variables to one another. Boyle’s law states that at constant temperature, the volume of a gas is inversely proportional…

Neutralisation

Neutralization is a chemical reaction between an acid and a base, resulting in the formation of a salt and water. During this reaction, the hydrogen ions (H+) from the acid react with the hydroxide ions (OH-) from the base to form water, and the remaining ions combine to form a salt. The general chemical equation…

Dalton’s atomic theory

Dalton’s atomic theory, proposed by John Dalton in the early 19th century, was a fundamental theory of chemistry that laid the groundwork for the modern understanding of atoms and their properties. The theory included the following key postulates: Dalton’s theory was an important contribution to the development of modern chemistry, as it provided a framework…

Scalar multiplication

Scalar multiplication is a mathematical operation that involves multiplying a scalar (a real number) by a vector, resulting in a new vector. The scalar multiplication of a vector is represented as: c * v = (c * v1, c * v2, c * v3, …, c * vn) where c is the scalar, v is…

Maximum and Minimum values of a function

The maximum and minimum values of a function refer to the largest and smallest values that the function takes on, respectively. To find the maximum and minimum values of a function, we can use the following steps: It’s important to note that a function may not have a maximum or minimum value if it is…

Inverse trigonometric

The inverse trigonometric functions are a set of functions that allow us to find the angle or angles associated with a given trigonometric ratio (sine, cosine, tangent, etc.). They are denoted by the prefix “arc” or “inverse” and the abbreviation of the trigonometric function, for example: For example, if we want to find the angle…

Derivatives of polynomial

The derivative of a polynomial is obtained by differentiating each term of the polynomial with respect to the variable. For example, let’s consider the polynomial: f(x) = 5x^3 + 2x^2 – 7x + 4 To find its derivative, we differentiate each term with respect to x: f'(x) = (d/dx)(5x^3) + (d/dx)(2x^2) – (d/dx)(7x) + (d/dx)(4)…

Chain rule

The chain rule is a fundamental rule in calculus that allows you to differentiate a function that is composed of two or more functions. More specifically, if you have a function f(x) that is composed of two functions g(x) and h(x), such that f(x) = g(h(x)), then the chain rule states that: f'(x) = g'(h(x))…

Continuity of composite functions

The continuity of composite functions is governed by the following theorem: Let f be a function defined on an interval I containing a point a, and let g be a function defined on an interval J containing f(a). If f is continuous at a and g is continuous at f(a), then the composite function g…

Equation of a straight line in space

In three-dimensional space, the equation of a straight line can be written in vector form as: r = a + t(b-a) where “r” is a position vector that represents any point on the line, “a” is the position vector of a known point on the line, “b” is the position vector of another known point…
