1. In order to make 1 salad it requires 1 head of lettuce, two tomatoes and three carrots. What would be the coefficients for th
pogonyaev

Answer:

3 salad = 3 lettuce + 6 tomatoes + 9 three carrots

Coefficients: 3, 6, 9

Explanation:

1 salad = 1 lettuce + 2 tomatoes + 3 three carrots

<em>Multiply all the coefficients of 1 salad by 3:</em>

3(1 salad) = 3(1 lettuce + 2 tomatoes + 3 three carrots)

<em>Expand the equation:</em>

3 salad = 3 lettuce + 6 tomatoes + 9 three carrots

sesenic [268]

Answer:

91.2 nm

Explanation:

The Rydberg equation is given by the formula

     1/ λ  = Rh ( 1/ n₁² - 1/ n₂²)

where

λ is the wavelength

Rh is Rydberg constant

and n₁ and n₂ are the energy levels of the transion.

We can see from this equation that the wavelength is inversely proportional to the difference of the squares of the inverse of the quantum numbers n₁ and n₂. It follows then that the smallest wavelength will be given when the the transitions are between the greatest separation between n₁ and n₂ whicg occurs when n1= 1 and n₂= ∞ , that is the greater the separation in energy levels the shorter the wavelength.

Substituting for n₁ and n₂ and solving for λ :

  1/λ = 1.0974 x 10⁷ m⁻¹ x ( 1/1² -1/ ∞²)  =  1.0974 x 10⁷ m⁻¹ x ( 1/1² - 0) =

  λ = 1/1.0974 x 10⁷ m = 9.1 x 10⁻8 m = 91.2 nm

What does the name 2–butene tell you about this hydrocarbon's molecular structure?
jenyasd209 [6]
The suffix -ene tells that there is a double bond present in the molecule, and the 2 tells where in the molecule the bond is located. The molecule looks like this:


CH3-CH=CH-CH3

-ane indicates single bonds
-ene indicates at least one double bond
-yne indicates at least one triple bond
