Peroxide comprises a group of peroxides in which each oxygen atom, usually carbon or hydrogen, is bound to the other oxygen and to another atom.... View Article
If a large aluminium surface is being washed, soak a cloth in vinegar and scrub it through the oxidation process. In addition to cleaning... View Article
In some reaction, sodium metal is used as a catalyst. A catalyst is a material used without undergoing any alteration itself to speed up or slow... View Article
In a reversible process, the entropy of the universe stays unchanged, but in an irreversible (spontaneous) process, the entropy of the universe... View Article
A measure of a system's degree of disorder is entropy, represented by S. There is no net shift in entropy if a reversible mechanism occurs.... View Article
Einstein then spent 10 years attempting to incorporate acceleration in the theory, publishing his general relativity theory in 1915. In it, he... View Article
Iron(III) oxide is also referred to as rust with the formula Fe2O3 xH2O, and this label is useful to some degree, since rust has many properties... View Article
Oscillation refers to any periodic motion that travels around the place of equilibrium at a distance and repeats itself over and over for a... View Article
The orbitals of the 3d have far greater energy than the orbitals of the 4s. So because the orbitals of the 4s have the lowest energy, first it... View Article
Borax is also quite alkaline, like washing soda, but not quite at the same degree as the other ingredient. For thousands of years, Borax has been... View Article
A s orbital, a set of (3)p orbitals and a set of (5)d orbitals form the 3rd subshell. Each orbital carries 2 electrons and you can actually find... View Article
The resistance of galvanised steel to rust corrosion depends largely on the type and thickness of the protective galvanised zinc coating, but... View Article
A scale is a measuring system used by architects and engineers to help them draw on a scale that is not full size. To measure real sizes, a law... View Article
An electromechanical device used to detect and show an electric current is a galvanometer. A galvanometer acts as an actuator in response to... View Article
The full transition between atoms of valence electron(s) is ionic bonding. It is a type of chemical bond that produces two ions with opposite... View Article
The value of the mole in precisely 12 grammes of pure carbon-12 is equal to the number of atoms. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 x 1023... View Article
Polymers are substances which are made up of long molecular chains. The long chains give them both solid and liquid properties. As the most... View Article
Between the planets and the sun, no repulsion occurs. To sustain circular movement, you need to apply a centripetal force on a moving object, and... View Article
It is not possible to reverse entropy in a closed system. Therefore, as changes between events progress, all closed systems over time will tend... View Article
