Answer:
Polyester
Acrylic
Nylon
Are all made of fossil fuels.
Acid rain is formed by chemicals let off into the atmosphere further introducing the nitrogen oxides which are attached to the water vapour and than mixed together further making acid rain which contains a pH scale of 6 a pale light acid though very much effective.

Answer : The correct option is, (B) bent, 2, and 
Explanation :
Formula used :
![\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electron%20pair%7D%3D%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D)
where,
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
The given molecule is, 
![\text{Number of electrons}=\frac{1}{2}\times [5+2+1]=4](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electrons%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%5B5%2B2%2B1%5D%3D4)
Number of bond pair = 2
Number of lone pair = 2
The total number of electron pair are 4 that means the hybridization will be and the electronic geometry of the molecule will be tetrahedral.
But as there are 2 atoms around the central oxygen atom, the third and fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent or angular.
Hence, the correct option is, (B) bent, 2, and
To be able to answer this equations, we must set given information. Suppose the reaction to yield NO is:
N₂ + O₂ → 2 NO
Next, suppose you have 1 g of each of the reactants. Determine first which is the limiting reactant.
1 g N₂ (1 mol N₂/ 28 g)(2 mol NO/1 mol N₂)= 0.07154 mol NO present
Number of molecules = 0.07154 mol NO(6.022×10²³ molecules/mol)
<em>Number of molecules = 4.3×10²² molecules NO present</em>
Answer is in that reaction each iron atom loses three elections
