Explanation:
The ionization constant of the water = at a temperature of and pressure of 20 MPa
Water dissociates as;
The expression for the ionization constant is :
For pure water,
So,
The concentration of the hydroxide ions, .

Answer:
A. would be the most logical answer in this situation
Explanation:
See the point is when veterinarians give dogs the vaccine for rabies this exclusive medicine kills the cells that contain virus so therefore A. is the correct answer
Hope this helped five starts and Branliest would be appreciated ;D
Answer:
a) The work done is 10.0777 kJ
b) The water's change in internal energy is -122.1973 kJ
Explanation:
Given data:
1 mol of liquid water
T₁ = temperature = 100.9°C
P = pressure = 1 atm
Endothermic reaction
T₂ = temperature = 100°C
1 mol of water vapor
VL = volume of liquid water = 18.8 mL = 0.0188 L
VG = volume of water vapor = 30.62 L
3.25 moles of liquid water vaporizes
Q = heat added to the system = -40.7 kJ
Questions: a) Calculate the work done on or by the system, W = ?
b) Calculate the water's change in internal energy, ΔU = ?
Heat for 3.25 moles:
The work done:
The change in internal energy:
Answer: Because when you blow air /gas into a balloon you fill it with air particles ,so they more you blow u blow in more air particles so they tend to collide with each other ,so as they hit the walls of the balloons pressure is exerted ,so the pressure keeps the balloon inflated with its shape
