Answer:
A wave reflection interaction (reflected by the wall)
Explanation:
In a reflection, the propagating wave is bounced off the reflecting surface because the medium of the surface prevents the propagation of the wave through it, such that wave is redirected at an angle equal to the angle of incident on the reflecting surface
Reflection takes place with the different forms of waves, such as sound wave, water waves, and light wave
The objects around us are seen with the aid of reflection of light from a light source such that the reflected light enters our eyes after being reflected on the surface of the object, and the object is seen.
Answer:
The correct answer is option B. From 200K to 400K
Explanation:
Hello!
Let's solve this!
The ideal gas equation is the following PV = nRT
Where the variables are:
P: pressure
T: temperature
V: volume
R: universal constant of ideal gases
n: number of moles
We see in the equation the proportional relationship of volume with temperature.
We deduce that if the volume increases twice, then the temperature increases twice.
The temperature has to be in Kelvin, that's why we chose that answer.
Of the options, the correct answer is option B. From 200K to 400K
Answer:
imbibición
Explanation:
La propiedad responsable del fenómeno observado es la imbibición de la puerta de madera maciza.
La imbibición se refiere a una situación en la que las partículas sólidas de una sustancia absorben agua sin formar una solución.
A medida que la puerta de madera absorbe agua, se hincha. Esto es responsable del levantamiento de la puerta. Esta absorción de agua ocurre cuando la temperatura y la humedad relativa son altas. Esto es así porque el aire más cálido retiene más humedad.
Answer:
2.01 moles of P → 1.21×10²⁴ atoms
2.01 moles of N → 1.21×10²⁴ atoms
4.02 moles of Br → 2.42×10²⁴ atoms
Explanation:
We begin from this relation:
1 mol of PNBr₂ has 1 mol of P, 1 mol of N and 2 moles of Br
Then 2.01 moles of PNBr₂ will have:
2.01 moles of P
2.01 moles of N
4.02 moles of Br
To determine the number of atoms, we use the relation:
1 mol has NA (6.02×10²³) atoms
Then: 2.01 moles of P will have (2.01 . NA) = 1.21×10²⁴ atoms
2.01 moles of N (2.01 . NA) = 1.21×10²⁴ atoms
4.02 moles of Br (4.02 . NA) = 2.42×10²⁴ atoms
That statement is true. Hope I was of assistance :)
