3. The height of the graduated cylinder when measuring the volume of co2 (g) produced is adjusted to equalize the pressure in the graduated cylinder with the atmospheric pressure.
We discovered that when the water level within the graduated cylinder is higher than the water level outside, the gases inside the graduated cylinder have a lower pressure than the atmospheric pressure. It would then be possible to equalize pressure by changing the graduated cylinder's water level to match the water level outside.
Therefore last option or 3rd option is the correct choice.

Answer:
1.301 × 10⁻¹² m
Explanation:
Step 1: Given and required data
- Energy of the electromagnetic wave (E): 1.528 × 10⁻¹³ J
- Planck's constant (h): 6.626 × 10⁻³⁴ J . s
- Speed of light (c): 3.00 × 10⁸ m/s
Step 2: Calculate the wavelength (λ) of the electromagnetic wave
We can calculate the wavelength of the electromagnetic wave using the Planck-Einstein's relation.
E = h × c / λ
λ = h × c / E
λ = (6.626 × 10⁻³⁴ J . s) × (3.00 × 10⁸ m/s) / 1.528 × 10⁻¹³ J
λ = 1.301 × 10⁻¹² m
~Hello There!~
35 - 18 = 17
17 electrons means 7 outer shell electrons
Group number 7 - The Halogens
Electron configuration is 2. 8. 7
3 shells therefore in period 3
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^

Answer:
Verdadero.
Explanation:
¡Hola!
En este caso, dado que las propiedades periódicas nos hablan de un comportamiento específico sobre los elementos en la tabla periódica, resulta primeramente necesario recordar que la electornegatividad nos dice que tan fuerte es un elemento para atraer electrones de valencia de otros elementos.
De este modo, inferimos que es verdadero, ya que de hecho la electronegatividad nos define el tipo de enlace, basado en la diferencia de electronegatividades de los elementos enlazados, de acuerdo con la imagen adjunta.
Saludos!
