1. molarity = (moles)/vol in litres
0.5=[(weight/40)*1000]/4
0.5 = weight/16
weight of NaOH = 8 grams
2. weight = 0.45*850*84/100 gms
molecular weight = 85m (not sure abt this)
The ratio that show the relationship between moles of each reactant and product in the reaction that is
N2 + 3 H2 = 2NH3
the ratio is as follows
1mole N2 : 3 mol H2 :2mol NH3
This ratio is from equation since there is 1 mole of N2 reacted with 3 moles of H2 to produce 2 moles of NH3

Answer:
There is an overall release of energy when bonds form.
Explanation:
There is a general release of energy when bonds form. This energy is called bond energy.
Bond energy is involved in the breakdown or formation of one or more bonds between atoms of a molecule. Atoms bond with each other to achieve their electronic stability, that is, they move from a higher energy situation to a lower energy one. With this we can state that when the bond between atoms is formed, energy is released; therefore, its breakdown depends on energy absorption.
