The greater the electronegativity distinction, the more ionic a bond is. Electronegativity determines the bond with the most covalent character.... View Article
Due to its high resistivity and not oxidising at high temperatures, nichrome, an alloy of nickel and chromium, is also used as a resistor wire... View Article
When extracting Cu from its sulphide ore, the ore is partially roasted in the air in order to supply its oxide. The remainder of the sulphide... View Article
Both the melting and boiling points decrease down the group. Alkali metals in the metal crystal lattice have low binding energy since there is... View Article
There will be no electrons left to form a bond between the two boron atoms if one of the boron atoms in diborane attaches itself to three... View Article
Owing to the overlap of orbitals, resonance exists. Double bonds, formed from the overlap of 2p orbitals, are composed of pi bonds. In these pi... View Article

Diluted sulphuric acid is the acid used in this titration. Nitric acid is not used because it is an oxidising agent itself, and hydrochloric acid... View Article
The KCl ions come from a strong acid (HCl) and a strong base acid (HCl) (KOH). Therefore, no ion can impact the solution's acidity. The KCl ions... View Article
