Predict whether a reaction will occur when elemental bromine and lithium chloride are mixed

Reaction will not occur

In voltaic series  

Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au  

The more to the left, the metal is more reactive (easily release electrons) and the stronger reducing agent  

The more to the right, the metal is less reactive (harder to release electrons) and the stronger oxidizing agent  

So that the element located on the left can push the element on the right in the redox reaction  

For Halogen , Oxidizing strength: F2> Cl2> Br2> I2

Reaction of elemental bromine and lithium chloride

Br₂ + LiCl

Bromine is less reactive than Chlorine(Chlorine cannot be reduced by Bromine), so reaction will not occur

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

i believe the answer is a.
