FCH₂COOH is the strongest acid out of all.

Since the electron withdrawing inductive effect (-I effect) of the halogens decreases in the order of F>Cl> Br> I , therefore the acidic strength of the α- halo acids decreases in the same order.

FCH₂COOH  >  ClCH₂COOH   >   BrCH₂COOH   >   ICH₂COOH.

x128 = 162x

Then x² = 162x128

   = Sqrt of 8² x 6² x 3²

   = 8 x 6 x 3

   x²  = 144.

 x  = 12.

Natural Rubber is a Polymer derived from Isoprene. 

• Natural rubber is an addition polymer that is obtained as a milky white fluid known as Latex from a Tropical Rubber Tree.

Let the number be 'N'
Given N + 30N/100 = 390
=> 130N/100 = 390
=> N = 390 x 10/13
=> N = 300.

Computer Architecture refers to how a computer system is designed and what technologies it is compatible with. In brief, Computer architecture is a specification detailing how a set of software and hardware technology standards interact to form a computer system or platform.  

The Von Neumann Architecture, which is also known as the Von Neumann Model and Princeton architecture, is a computer architecture based on the 1945 description of computer by the mathematician and physicist John von Neumann.

The common greenhouse gas containing only hydrogen and oxygen is H2O, this is water vapor.

The common greenhouse gases are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.

The composition (chemical formula) of those gases are:

Water vapor: H2O
Carbon dioxide: CO2
Methane: CH4
Nitrous oxide: NO
Ozone: O3.

As you see the only one of those that contains only hydrogen and oxygen is H2O, water vapor.

4 is father of 1 and grandfather of 6. So, 1 is father of 6. Thus, 4 and 1 are the two fathers.
3 is the sister of 6. So, 3 is the daughter of 1. Since there is only one mother, it is evident that 5 is the wife of 1 and hence the mother of  3 and 6. So, 2 is brother of 1. There are three brothers. So, 6 is the brother of 3. Hence, 2 and 1 are brothers. 6 is the brother of 3. So, three brothers are 1, 2, 6.
