Answer:
The pOH is 4, 44 and the solution is basic.
Explanation:
The pOH is a measure of the concentration of OH (hydroxyl) ions in the solution.
The pOH is calculated as :
pOH = -log (OH-)= -log (3.67 x 10-5 )= 4, 44. In this case, the solution is basic.
The p0H scale ranges from values of 0 to 14 (less than 7.0 is basic and greater than 7.0 is acidic, a pH = 7.0 is neutral)

Answer:
Koverall [NO]^2 [Br2]
Balanced chemical reaction equation;
2NO + Br2 ⇄2NOBr
Explanation:
Consider the first step in the reaction;
NO(g) + Br2(g) ⇄ NOBr2(g) fast
The second step is the slower rate determining step
NOBr2(g) + NO(g) ⇄ 2NOBr(g)
Given that k1= [NOBr2]/[NO] [Br2]
k2= [NOBr2] [NO]
The concentration of the intermediate is now;
[NOBr2]= k1[NO][Br2]
It then follows that overall rate of reaction is
Rate= k1k2[NO]^2 [Br2]
Since k1k2=Koverall
Rate= Koverall [NO]^2 [Br2]
Answer:
Independent
Explanation:
Independent Variable is the volume of the object. Dependent Variable is the mass of the object. So it
