Use the iupac nomenclature rules to give the name for this comping caoh)2

By criss crossing the charge numbers we find the chemical formula of a compound

For example Aluminium chloride

Al has charge and Cl has charge  

3 becomes the subscript of Cl and 1 becomes the subscript of Al  

So the chemical formula will be

Ionic compounds are named using format as follows  

Metal’s name + root word of the non metal + ide ending (when the metal has only one type of charge)

Example NaCl is named as Sodium + chlor + ide = Sodium chloride

Metal’s name + charge in roman numeral + root word of non metal + ide ending (when the metal possess more than one type of charge)

Example

is named as Iron+(II)+chlor+ide =Iron(II)chloride

 is named as Iron+(III)+chlor+ide =Iron(III)chloride

From the formula CuO we get to know the charge numbers of Cu is and O is

CuO is Copper (II) oxide  

Metal + roman numeral for charge + root word of non metal + ide ending used in this

It is an ionic compound since it has a metal and a non metal.

When there is a polyatomic ion present for example the name of the polyatomic ion is used as it  is instead of  ’ide’ ending  

Thus is Sodium phosphate

Ca possess only one type of charge that is 2+ .So we don’t use roman numeral for the metal.

is Hydroxide ion and it is a polyatomic ion

So the name of the compound is Calcium hydroxide

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.
