M_r of MgCl₂ = 24.3 + 2(35.5) = 95.3 Moles added = 2.11/95.3 = 0.02214 Mol of cl^-  added = 20.02214 = 0.04428 Conc = 0.04428/(3010^-3) = 1.48 moldm^-...

Benzene has a chemical formula of C6H6, 6 carbon atoms in a ring with each bound to one hydrogen atom (aromatic hydrocarbon) - 3 covalent bonds for each carbon atom Planar regular hexagon shape with 120 d...

Overall the catalyst increases the rate of reaction. It does this by adding an alternative pathway for the reagents to react, this alternative path way has a much lower activation energy than the original...

In alkanes, such as propane, the carbon atoms are sp³ hybridised, meaning that each carbon atom has 4 sp³ molecular orbitals associated with it available for covalent bonding. These ...

Diamond is covalently bonded and has a giant covalent structure. Covalent bonds require lots of energy to break as they are strong so diamond has the hig...
