Question 1 (Mandatory) (2.5 points)

Chemistry
1 answer:
natita [175]3 years ago
4 0
I believe that the answer for question 1 is 4 and the reason for that is because that’s how the water cycle work and how it keeps going and it’s all because of the sun and the answer for 2 is 1and it’s because the carbon cycle is when is being taken in by plants so they can be able to release oxygen but it also need sunlight to be able to make its own good and keep the cycle going

What is the momentum of a photon that has a wavelength of 3.00 102 nm? remember the wavelength of a photon is equal to planck's
marta [7]
De Broglie's equation is used to show that photons have both particle and wave nature. photons are quantized packets of energy. the wave nature of photons can be proven as they have a wavelength. the particle nature is given by them having both velocity and mass. 
de Broglies equation is;
λ = h / p 
where λ - wavelength 
h - Planck's constant 
p - momentum 
substituting the values in the equation 
p = h/λ
p = \frac{6.626 * 10^{-34}m^{2} kg/s }{3.00 *  10^{-7}  m}
p  = 2.20 x 10⁻²⁷ kgm/s
momentum of photon is 2.20 x 10⁻²⁷ kgm/s

6.0 L of gas in a piston at a pressure of 1.0 atm are compressed until the volume is 3.5 L. What is the new pressure inside the
dimulka [17.4K]

From the calculations and by the use of Boyles law, the new pressure of the gas is 1.7 atm

<h3>What are gas laws?</h3>

The term gas law is used to demonstrate the relationship between the volume, pressure, number of moles and temperature of a gas.

Using the Boyles law;

P1 = 1 atm

P2 = ?

V1 = 6 L

V2 = 3.5 L

P1V1= P2V2

P2= P1V1/V2

P2= 1 atm * 6 L/3.5 L

= 1.7 atm

A structural model of retinol is shown below. How many hydrogen atoms are
Nikitich [7]

Answer:

A. 30

Explanation:

Retinol is the chemical form of Vitamin A. It has a chemical formula of C20H30O.

It is processed when retinyl palmitate is broken down in the small intestine. Retinol helps in the proper regulation of eye cells hence a vital component in ensuring good eye sight.

It also helps in the neutralization of free radicals in the body and acts as an antioxidant which prevents cells of the body from ageing.

PLZZZ HELP ME ASAP
Vesna [10]

de Broglie's wave equation describes that particles have wave properties. The equation is  

   λ = h/mv

Where λ  is the wave length of the particle (m), h is the Planck's constant (6.62607 x 10⁻³⁴J s), m is the mass of a particle (kg) and v is the velocity (m/s).

λ = ?

h =  6.62607 x 10⁻³⁴ J s

m =200 g = 0.2 kg

v = 20 m/s

By substitution,

   λ  = 6.62607 x 10⁻³⁴ J s / (0.2 kg x 20 m/s)

   λ  = 1.66 x 10⁻³⁴ m

Hence, the wavelength of the 200 g ball 1.66 x 10⁻³⁴ m.
