Answer:- There are 32 valence electrons and it's tetrahedral in shape.
Explanations:- Atomic number of carbon is 6 and it's electron configuration is 
. It has 4 electrons in the outer most shell means it has 4 valence electrons.
Atomic number of Br is 35 and it's electron configuration is 
. It has 7 electrons in the outer most shell(2 in 4s and 5 in 4p) .
There is one C and four Br in the given compound. So, total number of valence electrons = 4+4(7) = 4+28 = 32
Four Br atoms are bonded to the central carbon atom and also there isn't any lone pair present on carbon. It makes it tetrahedral.

Answer: Effects of Mutations
A single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations with small effects. Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious.
Other common mutation examples in humans are Angelman syndrome, Canavan disease, color blindness, cystic fibrosis, Down syndrome, Duchenne muscular dystrophy, haemochromatosis, haemophilia, Klinefelter syndrome, phenylketonuria, Prader–Willi syndrome, Tay–Sachs disease, and Turner syndrome

When we balance the given equation
POCl₃(g) ⇄ PCl₃(g) + O₂(g)
We will get
2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)
Solution:
Balancing the given equation
POCl₃(g) ⇄ PCl₃(g) + O₂(g)
Balancing the number of O
2POCl₃(g) ⇄ PCl₃(g) + O₂(g)
Balancing the number of P and Cl
2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)
We get the balanced equation
2POCl₃(g) ⇄ 2PCl₃(g) + O₂(g)
The reaction quotient will be
Qc = [product] / [reactant]
Qc = [PCl₃(g) + O₂(g)] / [POCl₃(g) ]

Answer:
a. Gases ideales: relación entre todas las variables que influyen sobre los gases
Explanation:
La ecuación del gas ideal da la relación entre las variables; presión, volumen, temperatura y número de moles.
Según la ecuación del gas ideal; PV = nRT
P = presión del gas
V = volumen del gas
n = Número de moles del gas
R = constante de gas
T = temperatura del gas
El número de moles de SO2 se obtiene de;
n = PV / RT
n = 0,5 * 25 / 0,082 * 373
n = 12,5 / 30,586
n = 0,41 moles
