Answer: 42.14 g
Explanation: calcium nitrate -
, the molar mass of calcium nitrate = 164 g
<h3> formula used =
= no of moles </h3>
mass required =
= g
It will melt or the molecules inside of it will get hot
Aromatic compound has continuous cyclic structure with( 4n+2)π electrons (Huckels rule), where n = 0,1,2…
Here number of pi electron are 6, where 4 from two double bond and 2 from nitrogen non-bonding electrons, hence it has total 6 pi electrons, therefore
6= ( 4n+2)π
4 = 4n
n =1
Hence it is an aromatic compound
Reactant molecules collide more frequently and with greater energy per collision
