The material that will be able to pass the cell, would be characterized as being soluble. As in order for them to pass, they would be able to dissolve in one of the layers of the membrane, I believe.
Answer:
I do not know
Explanation:
I am vert sorry but I do not know the answer.
Answer:
713 nm. It is not visible with the naked eye.
Explanation:
Step 1: Given data
- Energy of light (E): 2.79 × 10⁻¹⁹ J
- Planck's constant (h): 6.63 × 10⁻³⁴ J.s
- Speed of light (c): 3.00 × 10⁸ m/s
Step 2: Calculate the wavelength of the light
We will use the Planck-Einstein equation.
E = h × c / λ
λ = h × c / E
λ = 6.63 × 10⁻³⁴ J.s × 3.00 × 10⁸ m/s / 2.79 × 10⁻¹⁹ J
λ = 7.13 × 10⁻⁷ m
Step 3: Convert "λ" to nm
We will use the relationship 1 m = 10⁹ nm.
7.13 × 10⁻⁷ m × (10⁹ nm/1 m) = 713 nm
This light is not in the 400-700 nm interval so it is not visible with the naked eye.
C: The electron moves to a lower energy level
Answer:
Safety Glasses- prevent chemicals, and small objects from getting into your eyes
Apron- Protect you from spills on your clothes (especially chemicals in the lab)
Eye Wash- flushes chemicals and small objects out of your eyes in case of emergency in the lab
Fire Extinguisher- Extinguish fires
Fire blanket- Extinguish fires ( by smothering small fires)
These were definitely went over in your class pay more attention next time :)
