Explanation:
Red blood cells are the carriers of oxygen from the lungs to everywhere else
in the body. If there is a high count of red cells in the blood, then <span>high levels
of oxygen will be available to the muscles.</span>
Answer:
K = 1.69M
Explanation:
For the reaction:
2NH₃(g) ⇄ N₂(g) + 3H₂(g)
K is defined as:
k = [N₂] [H₂]³ / [NH₃]² <em>(1)</em>
Molarity in equilibrium for each specie is:
NH₃(g): 2.0mol - 2x = 1.0mol/1L = 1M → X = 0.5mol
N₂(g): X = 0.5mol/1L = 0.5M
H₂(g): 3X = 1.5mol/1L = 1.5M
Replacing:
k = [0.5] [1.5]³ / [1]²
<em>k = 1.69M</em>
<em></em>

um i dont know anything about music sorry
Answer:
1024Å
Explanation:
The Rydberg equation is an empirical relationship equation expressed by Balmer and Rydberg which is given as:
1/λ = .............................(1)
where is the Rydberg constant given as , n is the transition level and the subscript f and i show the final and initial level numbers respectively. λ is the wavelength.
= 1
Using equation (1), we have
1/λ
=
=
=
= - 9763300
λ =
=
We should note that the negative sign we have is as a result of photon absorption whereby the hydrogen atom gains energy to undergo a transition from the lower energy level to a higher one. Wavelength does not have a negative value.
To convert to Å, we have
λ = = 1024Å
Therefore the wavelength of the photon in Å is 1024Å
