Sodium oxide has a formula of Na 2 O. Since sodium is a metal and oxygen is a non metal, sodium oxide is an ionic species. Sodium will lose an electron to form a cation and oxygen will gain 2 electrons to fo...

HA <----> H+ + OH-Acid:Adding an acid increases the concentration of H+ ions as acids are proton donors. These H+ ions react with the conjugate base, A-, to form HA and thus shift the equilibrium posit...

Propenal can be distinguished by adding bromine water, as it will go from a orange/brown solution to a colourless solution due to electrophilic addition. Propanal can be distingiushed from propanone by using...

In complete combustion, there is a sufficient supply of oxygen which is able to react with the burning hydrocarbon allowing the reaction products H 2 O and CO 2 to be formed. In incomplete combustion there i...

The enthalpy change of hydrogenation of benzene was shown to be less exothermic than 3 times that of hexene, therefore meaning that benzene does not contain three double bonds. X-ray imaging showed that benz...
