The relative atomic mass of Ne = 20.2. Therefore 20.2 g of neon contains 6.022 × 1023 Ne atoms.
Answer:
k = 2.647 x 10-2 M-2 s-1
Explanation:
2NO(g) +Cl2(g) --> 2NOCl(g)
Experiment [NO] (M) [Cl2] (M) Rate (M/s)
1 0.0300 0.0100 3.4 x 10-4
2 0.0150 0.0100 8.5 x 10-5
3 0.0150 0.0400 3.4 x 10-4
Frrom experiments 1 and 3;
Reducing the concentration of NO by a factor of 2 decreases the rate of the reaction by a factor of 4. This means the reaction is second order with respect to NO.
From experiments 2 and 3:
Increasing the concentration of Cl2 by a factor of 4 increases the rate by a factor of 4. This means the reaction is first order with respect to Cl2
The rate equation is given as;
Rate = k [NO]² [Cl2]
From experiment 1;
k = [NO]² [Cl2] / Rate
k = 0.0300² * 0.0100 / 3.4 x 10-4
k = 2.647 x 10-2 M-2 s-1
<h2>Bombarded α-Particles on a thin Sheet of Gold
</h2>
Explanation:
- Rutherford Atomic Model is also known as " The plum pudding model"
- Rutherford’s in his experiment bombarded α-particles which are of high energy on a thin sheet of gold nearly 100 nm of thickness and observed the trajectory path of these particles after interacting with the foil of gold.
- He placed a fluorescent screen of zinc sulfide around the thin gold foil to study the trajectory path of the α-particles and its deflection.
- Most of the α-particles passed through the gold foil were not deflected as most of the internal space of the atom was empty.
- The result was that the positive charge of the atom occupies very little space.
