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
Answer;
-Decrease
if the producer population decreased then the size of the herbivore population will consequently decrease.
Explanation;
Producers
are organisms that make make their own food through a process known as photosynthesis, e.g. plants such as grasses. Herbivores are the organisms which feed on producers. Examples of herbivores are rabbits, giraffes etc.
-An increase in producer population means that there will be a a corresponding increase in the population of herbivores while a decrease in the size of producers will cause a decrease in the population of herbivores.
I think it is 25 degrees F.

Answer:
Explanation:
Hello!
In this case, according to the given balanced chemical reaction:
We can see there is 1:1 between benzene and chlorobenzene as the relavant product; thus, since the molar mass of benzene is 78.11 g/mol and that of chlorobenzene is 112.55 g/mol, the theoretical yield for this reaction turns out:

Answer:
A. 35Cl1-
Explanation:
Chlorine needs 1 more electron to have full octet thus will take 1 electron and possess a -1 charge.
