Answer:2.2059
Explanation:find their total ram is(14+(1×3))
Find the portion occupied by
H2 which is three
Divide h2 by total ram then multiply by mass
Answer:
less, decreases
Explanation:
When the pressure of an atmosphere occurs because of the force exerted so at the time of the higher altitudes, the air mass i.e. above the earth should be less as the air is attracted towards surface of an earth because of the gravity and air contains the mass that shows near the surface area so automatically the air density reduced due to which the mass also decreased
<u>Answer:</u> The wavelength of the photon is 486.2 nm and it lies in the visible region
<u>Explanation:</u>
To calculate the wavelength of light, we use Rydberg's Equation:
Where,
= Wavelength of radiation
= Rydberg's Constant = 
= Higher energy level = 4
= Lower energy level = 2
Putting the values in above equation, we get:
Converting this into nanometers, we use the conversion factor:
So, 
As, the range of wavelength of visible light is 400 nm - 700 nm. So, the wavelength of the given photon lies in the visible region
Hence, the wavelength of the photon is 486.2 nm and it lies in the visible region
Answer:
206 c
Explanation:
Use the Charles' Law because you have the volume and temperature given.
V1 / T1 = V2 / T2
Let's list the given:
V1 = 0.668 L
V2 = 0.942 L
T1 = 66.8 C (339.8K)
Convert all Celsius temps to Kelvin. Just add 273.
Asked: T2
Derive the formula for T2.
T2 = V2T1 / V1
= (0.942)(339.8) / 0.668
= 479K
Since the temp should be in C, just subtract 273 from 479K.
The answer is 206 C.
