Gallum: Z = 31
electron configuration: [Ar] 4s^2 3d10 4s2 4p1
Highest energy electron: 4p1
Quantum numbers:
n = 4, because it is the shell number
l = 1, it corresponds to type p orbital
ml = may be -1, or 0, or +1, depending on space orientation, they correspond to px, py, pz
ms = may be -1/2 or +1/2, this is the spin number.
Atomic radii increase when going down a group and decreases when going towards the anion periods. So A and D.
Answer:
Both
Explanation:
The combined gas law is also known as the general gas law.
From the ideal gas law we assume that n = 1;
So;
PV = nRT
and then;
=
If we cross multiply;
P₁V₁T₂ = P₂V₂T₁
So;
T₁ = ![T_{2} \frac{P_{1}V_{1} }{P_{2} V_{2} }](https://tex.z-dn.net/?f=T_%7B2%7D%20%5Cfrac%7BP_%7B1%7DV_%7B1%7D%20%20%7D%7BP_%7B2%7D%20V_%7B2%7D%20%7D)
Also;
V₂ = ![V_{1} \frac{P_{1} T_{2} }{P_{2} T_{1} }](https://tex.z-dn.net/?f=V_%7B1%7D%20%5Cfrac%7BP_%7B1%7D%20T_%7B2%7D%20%7D%7BP_%7B2%7D%20T_%7B1%7D%20%7D)
So from the choices both are correct
Answer:
b
Explanation:
The number of vibrations per second is known as the frequency
Answer:
are produces are in a month.
Explanation:
Quantity of eggs produced by the chicken in a month = 284 dozens
1 dozen = 12 eggs
Number of eggs in a month:
![284 dozens = 284\times 12 eggs =3,408 eggs\approx 3.4\times 10^3 eegs](https://tex.z-dn.net/?f=284%20dozens%20%3D%20284%5Ctimes%2012%20eggs%20%3D3%2C408%20eggs%5Capprox%203.4%5Ctimes%2010%5E3%20eegs)
are produces are in a month.
