Firstly, to identify butanoic acid, adding a small amount of NaHCO₃ or any metal carbonates would allow effervescence tobe produced. The effervescence produced is CO₂ . To make sure ...

The forces between the iodine molecules are stronger compared to the ones between chlorine

The answer is optical isomerism. Optical isomerism exists when a carbon has 4 different groups attached to it. In Butan-2-ol, the second carbon has a hydroxy group, ethyl group, a methyl group and a hydro...

This is because when the metals are heated (burned), their electrons can briefly 'jump' from lower energy electron shells to higher energy electron shells. This requires energy to happen, and light is not...

First you must calculate the moles of Mg that originally reacted. moles = mass/Mr moles=48/24 moles= 2 Molar ratio of Mg to MgCl2 is 1:1 Therefore 2 moles of MgCl2 were produced moles= mass/Mr mass= moles...
