Answer:
volume of
required=20.1 ml
Explanation:
First calculate the number of mole of
,
given mass of
=23.4 gram ⇒this is the required mass to produce 40 gram silver chromate
molecular weight=194g/mol

mole=0.121 mol
molarity is given and we have also calculated the mole so we will use the relation between molarity,volume and mole i.e.


volume in L=0.0201 lire
volume of
required=20.1 ml

Ionic bonds are made up of a metal and a nonmetal elements while covalent bonds are are made up of two metal. So, you can just look at the periodic table and identify which compounds have two metals and which have one metal and one nonmetal. Also, those compounds with high electronegativity difference are very likely to be ionic while the opposite is covalent. HOWEVER, some compounds can be both covalent and ionic. For instance, if HCI gas is at higher temperatures, then it is ionic while it would be covalent at room temp.
Hope I've helped.

Answer:
Two covalent bonds form between the two oxygen atoms because oxygen requires two shared electrons to fill its outermost shell. Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell.
