I use many chemicals throughout my day‚ especially in the morning.The deodorant I use each morning includes Aluminium zirconium tetrachlorohydrex gly (Al4Zr(OH)12Cl4 Gly x nH2O). Aluminium zirconium tetrachlorohydrex gly can cause irritation in sensitive underarm areas. These irritations can cause allergic reactions like contact dermatitis‚ acne‚ or itching. The contact solution I use each morning includes Sodium Borate (Na2[B4O5(OH)4]·8H2O). According to my research‚ Sodium Borate is normally slightly

Bonds is something that retains and holds on together with one another. There are three major chemical bonds and they are‚ Ionic‚ Covalent‚ and Hydrogen bonds. An example of a covalent bond would be SCl^2 which is Sulfur dichloride. SCl^2 is a covalent bond because since they are close to each other in valence electrons‚ they have almost full outer shells so they share electrons with one another. A good example is table salt NaCl‚ because they are on opposite sides of the periodic table therefore

the formation of giant ionic lattices. Lattice enthalpy is defined as either the: ’the enthalpy change that occurs when one mole of a solid ionic crystal is broken into its ions in the gaseous state‚ at standard temperature and pressure. Because all the bonds in the ionic lattice are broken‚ it is an endothermic process‚ ∆H is positive. ’ The IB uses this definition. M+ (g) MX (s) + X- (g) or ’the enthalpy change that occurs when one mole of a solid ionic crystal is formed form

Electrolysis a) Electrolysis is the decomposition of a substance to give simpler substances. The substance being electrolysed has to be an ionic compound. b) The substance being decomposed is called the electrolyte. c) In electrolysis the electric current enters and leaves the electrolyte by conducting rods called electrodes. The positive electrode is called the anode and the negative electrode is called the cathode. d) For electrolysis to occur the electrolyte must be in liquid form so that

attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent Bonds Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms‚ in contrast to the transfer of electrons in ionic bonds. Such bonds lead to stable molecules if they share electrons in such a way as to create a noble gas configuration for each atom. Hydrogen gas forms the simplest covalent bond in the diatomic hydrogen molecule. The halogens such as chlorine also
