Answer: In covalent bonds, atoms share electrons, whereas in ionic bonds atoms transfer electrons. The reaction components of covalent bonds are electrically neutral, whereas for ionic bonds they are both charged. ... Covalent bonds are formed between two non-metals, whereas ionic bonds are formed between a metal and non-metal.
To segregate p-tert-butylphenol after you have removed it into NaOH arrangement one would accelerate the p-tert-butylphenol by adding 3M HCl to the cooled arrangement until the point when it is acidic. At that point as the phenol isolates as an oil, one needs to cool the blend in an ice shower to encourage crystallization. The precious stones that are then framed are the p-tert-butylphenol which can be isolated from the arrangement by filtration utilizing the Hirsch pipe
The elements oxygen and silicon make up most of the Earth's crust including silicate minerals such as quartz and feldspar
3Mg + N₂= Mg₃N₂
n(Mg)=12,2g÷24,4g/mol=0,5mol-limiting reagentn
(N₂)=5,16g÷28g/mol=0,18mol
n(Mg₃N₂):n(Mg)=1:3, n(Mg₃N₂)=0,166mol, m(Mg₃N₂)=0,166·101,2=16,8g.
%(N)= 2·Ar(N)÷Mr(Mg₃N₂) = 2·14÷101,2=27,66%=0,2766
%(Mg) = 3·Ar(Mg)÷Mr(Mg₃N₂)= 3·24,4÷101,2=72,34% or 100% - 27,66%= 72,34%.
C. On the left side .. what the chemical uses is always on the left and what it produces is always on the right.
