Answer:
The speed of sound in hydrogen gas is 361.5
Explanation:
It is given that the temperature is 50 .
The speed of sound in meter per second is calculated by an equation.
The equation states that speed of the sound in meter per second is equal to the sum of the product of the temperature in degree celsius with 0.60 and a constant that is 331.5.
The equation is written as:
Put the value of T = 50 then the equation becomes,
Speed of sound (in m/s) = 361.5 m/s
Explanation:
J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. ... Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus.

Answer: pH = 10.92
Explanation:
To determine the pH of an aqueous solution, we use the following mathematical relation; pH = - log [H3O+]
= - log (6 x 10∧ -12)
= 12 - 1.08
pH = 10.92
