It is true yes :) happy to help
The answer is 10-12. The relationship of pH and [H+] is pH = -lg[H+]. And the higher pH, the stronger base is. So the strongest base has the lowest concentration of H+.
Answer:
Explanation:
Option A is the correct answer
Boyle's law states that pressure is inversely proportional to volume of gas at constant temperature
PV = k
where P - pressure , V - volume and k - constant
P1V1 = P2V2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
substituting these values in the equation
1.25 atm x 0.75 L = P x 1.1 L
P = 0.85 atm
final pressure is B) 0.85 atm
Molar mass of NH_3
We know.
No of moles=Given mass/Molar mass
Now
Lets write the balanced equation
- There is 2moles of Ammonia
- 3moles of H_2
- 1mole of N_2
Now
For Hydrogen
For Ammonia
For Nitrogen
