Given: wavelength of Nitrogen laser (∧) = 337.1 nm = 337.1 X 10^-9 m
We know that, Energy of photon (E) = hc/∧ = hv
where, v = frequency of photon and c = speed of light = 3 X 10^8 m/s
Thus, v = c/∧ = (3 X 10^8)/ (337.1 X 10^-9) = 8.899 X 10^14 s-1.
Answer: F<span>requency of nitrogen laser = </span>8.899 X 10^14 s-1.
The number of bacon double cheeseburgers that can be made starting with the given ingredients is; five.
<h3>What are Limiting Reactants?</h3>
Limiting reactant(s) as the name implies are reactants whose availability is limited and hence, the the rate at which products are formed is limited subsequently.
From the question, to determine the limiting Reactant;
- We must divide the available quantity of each Reactant by the required quantity for the production of one unit cheeseburgers.
Hence;
- 12 buns/1 = 12 cheeseburgers.
- 20 patties/2 = 10 cheeseburgers
- 24 slices of cheese/2 = 12 cheeseburgers
- 20 strips of bacon/4 = 5 cheeseburgers.
On this note, the limiting Reactant is strips of bacon and hence, the number bacon double cheeseburgers that can be made starting with the given ingredients is; five.

Genetics cause these disorders, after the trait is passed down to the offspring
Explanation:
Repeating decimals are considered rational numbers because they can be represented as a ratio of two integers. the number of 9's in the denominator should be the same as the number of digits in the repeated block.
The molarity of a solution formed when you add 200 mL of water to 50 mL of 5. 0 M HCl is 1.25M.
<h3>How to calculate molarity?</h3>
The molarity of a solution can be calculated using the following formula:
M1V1 = M2V2
Where;
- M1 = molarity of a base
- M2 = molarity of acid
- V1 = volume of base
- V2 = volume of acid
M1 × 200 = 50 × 5
200M1 = 250
M1 = 250/200
M1 = 1.25M
Therefore, the molarity of a solution formed when you add 200 mL of water to 50 mL of 5. 0 M HCl is 1.25M.
