[H3O+] is just the same with [H+]. There are quite a few relationships between [H+] and [OH−] ions. And because there is a large range of number between 10 to 10-15 M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+ ][OH- ] = 10-14

He discovered this by firing Alpha particles at a gold foil and most alpha particles went through the foil and a few were deflected. The area where the alpha particles were deflected were assumed where the small dense positively charged nucleus was located. And electrons were scattered in the empty space out side the small nucleus.

Answer:
The temperature at which the glass vessel shatter is = 341.33°c
Explanation:
Initial temperature = 18 °c = 291 K
Initial Pressure = 0.9 atm
Final pressure = 1.9 atm
From ideal gas equation
P V = m R T
Here volume & mass & gas constant is constant so Pressure is directly proportional to the temperature.
= 613.33 K = 341.33°c
Therefore the temperature at which the glass vessel shatter is = 341.33°c
