First look at the periodic table to find the atomic number - 14.Then if it is a stable atom with no valency, the electron number will be equal to the proton number - 14.To work out the number of neutrons,...
The electron density in the phenol ring is higher than that of the benzene ring due to the presence of the OH group. This allows the electron substitution reaction to happen without a sulphuric acid catal...
Group 2 elements are metals that all form cations in a chemical reaction. This means they lose their valence electrons to become positive (2+) ions. Their reactivity depends on how easily the atoms can lo...
Halogens are electronegative than the adjacent carbon atoms in haloalkanes.Therefore they have a tendency to attract the pair of electrons in a covalent bond, forming a polar bond.The carbon becomes elect...
Balanced equations: CaCO3 + 2 HCl --> CaCl2 + H2O + CO2 , HCl + NaOH --> NaCl + H2O HCl moles that react overall: (80.0 cm3 x ...
