Answer:

v =  \sqrt{ \frac{2ke}{m} }

option D is the correct option.

Here,

If an object of mass 'm' moving with a velocity'v' then,

kinetic \: energy =  \frac{1}{2} m {v}^{2}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    {v}^{2}  =  \frac{2ke}{m}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  {v}^{2}  =  \sqrt{ \frac{2ke}{m} }

hope this helps...

ddd [48]
From the equation:
4mol Li react with 1 mol O2
Molar mass Li = 7g/mol
mol in 84g Li = 84/7 = 12 mol Li
From the equation - 12 mol Li will react with 3 mol O2

At STP 1 mol O2 has volume = 22.4L
<span> At STP 3 mol O2 has volume = 3*22.4 = 67.2L O2 gas will react. </span>
