Answer:
42.8
Explanation:
A particle travelling through potential difference V has energy E =qV = 1/2mv²
v = √(2qV / m)
ve = √(2qV / me)
vh = √(2qV / mh)
ve / vh = √( (2qV / me) ÷(2qV / mh) = √ ( mh / me ) where mh = mass of hydrogen ion and me is mass of electron, V voltage is the same, ve is speed of electron and vh is the speed of hydrogen ion
ve / vh = √ ( mh / me ) = √ ( 1.67 × 10⁻²⁷ kg) / ( 9.11 × 10 ⁻³¹ kg) = 42.8
I believe the answer is A.
Be, Mg, Ca increasing first ionization energy
Answer:
The answer is
<h2>0.95 atm</h2>
Explanation:
To solve the question we use the following conversion
That's
1 mmHg 
0.0013 atm
So we have
If 1 mmHg 0.0013 atm
Then 732 mmHg will be
732 × 0.0013 atm
We have the final answer as
<h3>0.95 atm</h3>
Hope this helps you
Answer:
Difussion
Explanation:
Diffusion is the result of a totally random phenomenon in which the molecules of a fluid come and go between two vessels that can be connected by a pipe. These molecules travel in a single direction, where the solute is more concentrated to where it is more diluted.
This movement of particles will be modified according to the length or area of the pipe and the concentration of solute. The greater the difference in solute concentration along the tube, the greater the diffusion
