Answer:
Topographic maps generally shows Natural features such as Rivers and Lakes.
sometimes they also show some features made by humans like brodges, elevations etc.
Answer:
[N2] = [O2] = 0.841M
And [NO] = 0.00172M
Explanation:
The equilibrium constant of this reaction, Kc, is:
Kc = 2400 = [N2] [O2] / [NO]²
<em>Where [] are the equilibrium concentration of each specie.</em>
<em />
The initial concentration of [N2] = [O2] = 0.850M. The equilibrium will shift to the left in order to produce NO. The equilibrium concentrations are:
[N2] = [O2] = 0.850M - X
And [NO] = 2X
Replacing:
2400 = [0.850-X]² / [2X]²
9600X² = 0.7225 - 1.7 X + X²
0 = 0.7225 - 1.7 X - 9599X²
Solving for X:
X = -0.0088M. False solution, there is no negative concentrations.
X = 0.00859M. Right solution.
Replacing:
[N2] = [O2] = 0.850M - 0.00859M
And [NO] = 2*0.00859M
[N2] = [O2] = 0.841M
And [NO] = 0.00172M
Answer:
V2 = 9.58 Litres.
Explanation:
Given the following data;
Initial volume = 25 L
Initial pressure = 115 kPa
Final pressure = 300 kPa
To find the new volume V2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
Substituting into the equation, we have;




V2 = 9.58 L
Therefore, the new volume is 9.58 litres.
Answer:
11% is the percentage of butanoic acid that is dissociated.
Explanation:

Initially
c 0 0
At equilibrium
(c-cα) cα cα
Concentration of acid = c = [HBu] = 1.2 mM = 0.0012 M
Dissociation constant of butanoic acid = 
Degree of dissociation =
Dissociation constant of an acid is given by:
![K_a=\frac{[Bu^-][H^+]}{[HBu]}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%5BBu%5E-%5D%5BH%5E%2B%5D%7D%7B%5BHBu%5D%7D)




11% is the percentage of butanoic acid that is dissociated.
