PV = nRT
Pressure times volume = number of moles times ideal gas constant times temperature
50mL = .05L
1 atm (.05) = n (.0821) (273)
.05 = n (22.4133)
.022 = n (number of moles)
6.022E23 molecules = 1 mole
.022 x 6.022E23 = 1.325E23 molecules
This will give substituted product which will be by SN2 mechanism
so here we will get product with inverted geometry
In SN2 mechanism the nucleophile attacks from back side and we always get product with inverted geometry
This is known as Walden inversion.
CO2 and H2O react to form H2CO3 and two bonds are broken each in CO and H2O to form H2CO3.
<h3>What is chemical bonding?</h3>
Chemical bonding refers to the forces of attraction which hold atoms of the same or different elements together in order to form stable compounds or molecules .
Chemical bonding may be either ionic or covalent.
The greater the number of bonds in a compound, the more stable the compound.
During chemical reactions, bonds are broken and new binds are formed.
There are two bonds each in CO2 and H2O.
This, in the reaction between CO2 and H2O react to form H2CO3, , the number of bonds broken in H2O is two and in CO2 is two.

Answer:
Aluminum , iron , gold , silver , nickels etc are the type of elements form metallic bonds .
Answer:
Coefficient of 
is more than 4
Explanation:
Oxidation: 
- Balance charge:
......(1)
Reduction: 
- Balance Cr:
- Balance O and H in acidic medium:
- Balance charge:
.......(2)
![[3\times Equation-(1)]+Equation(2)](https://tex.z-dn.net/?f=%5B3%5Ctimes%20Equation-%281%29%5D%2BEquation%282%29)
gives balanced equation:
So coefficient of is more than 4
