Its pH is constant which is neither acid or base

The answer is 7.

Since pH values are made up of 14 numbers, and the smaller the number is, the more acidic a substance is, and the larger the pH value is, the more alkaline the substance is. So, the median number of the pH scale is 7. 

We can easily test the pH value of simple substances (liquid the best) by using pH paper, which you can easily get in drugstores, or pH meter, where you should be able to find in most laboratories. You'll have a chart to match with and you should get the value of 7 if it's pure water that you're testing.

At 350 k, kc = 0.142 for the reaction 2 brcl(g) ⇀↽ br2(g) + cl2(g) an equilibrium mixture at this temperature contains equal con

0.114 mol/l  
The equilibrium equation will be: 
Kc = ([Br2][Cl2])/[BrCl]^2  
The square factor for BrCl is due to the 2 coefficient on that side of the equation.  
Now solve for BrCl, substitute the known values and calculate. 
Kc = ([Br2][Cl2])/[BrCl]^2 
[BrCl]^2 * Kc = ([Br2][Cl2]) 
[BrCl]^2 = ([Br2][Cl2])/Kc 
[BrCl] = sqrt(([Br2][Cl2])/Kc)  
[BrCl] = sqrt(0.043 mol/l * 0.043 mol/l / 0.142) 
[BrCl] = sqrt(0.001849 mol^2/l^2 / 0.142) 
[BrCl] = sqrt(0.013021127 mol^2/l^2) 
[BrCl] = 0.114110152 mol/l  
Rounding to 3 significant figures gives 0.114 mol/l
