False.
It is expected to be 7.5, the mean of 7 and 10.
The number of atoms present in 0.10 mol of PtCl2(NH3) is calculated using Avogadro law formula
that is
1 mole = 6.02 x10^23 atoms
what about 0.10 moles = ? atoms
= 6..02 x10 ^23 x 0.1 = 6.02 x10^22 atoms
Hi! My answer would be D, USA.
Explanation:
We are provided with 5 pieces of an address. They are as followed.
12 Riverdale Lane, Apartment A, San Jose, California, and USA.
Imagine each of the five parts of Beck's address represents Earth, the Milky Way, the moon, the solar system, or the universe, based on their sizes. Which of the following parts of Beck's address would represent the solar system?
If we have to plug in Earth, the Milky Way, the moon, the solar system, and the universe, (all based on size,) we would first start with what "Apartment A" would be in this scenario. Apartment A is the smallest piece we have to work with, and so is the moon. This leads me to believe that the Moon should be plugged into Apartment A. Now, 12 Riverdale Lane is most likely going to be the Earth, since it is the second smallest one on our list. San Jose would turn into the Sun, California represents the Milky Way, and USA represents the solar system.
I sincerely hope I helped!
Have a wonderful day :)

Answer:
PART A: 412.98 nm
PART B: 524.92 nm
Explanation:
The equation below can be used for a diffraction grating of nth order image:
n*λ = d*sinθ
Therefore, for first order images, n = 1 and:
λ = d*sinθ
.
The angle θ
can be calculated as follow:
tan θ
= 9.95 cm/15.0 cm = 0.663 and
θ
=
(0.663) = 33.56°
Thus: d =λ/sin θ
= 461/sin 33.56° = 833.97 nm
PART A:
For a position of 8.55 cm:
tan θ
= 8.55 cm/15.0 cm = 0.57 and
θ
=
(0.57) = 29.68°
Therefore:
λ =d*sin θ
= 833.97*sin 29.68° = 412.98 nm
PART B:
For a position of 12.15 cm:
tan θ
= 12.15 cm/15.0 cm = 0.81 and
θ
=
(0.81) = 39.01°
Therefore:
λ =d*sin θ
= 833.97*sin 39.01° = 524.92 nm
