Answer is:  the maximum wavelength of light is 7.34 × 10⁻⁷ m.

E= 163 kJ/mol; bond energy of one mole of nitrogen.

E = 163000 J/mol ÷ 6.022·10²³ 1/mol.

E = 2.707·10⁻¹⁹ J; bond energy per molecule.

E = h·c/λ.

c = 3.00 × 10⁸ m/s; light speed.

h = 6.62607004·10⁻³⁴ J·s; Planck constant.

λ(photon) = h·c/E.

λ(photon) = 6.62607004·10⁻³⁴ J·s · 3.00 × 10⁸ m/s ÷ 2.707·10⁻¹⁹ J.

λ(photon) = 7.34 × 10⁻⁷ m.

λ(photon) = 734 nm.

How does changing the volume or temperature of a gas affect the pressure of that gas?
Masja [62]

Answer:

When a gas occupies a smaller volume, it exerts a higher pressure; when it occupies a larger volume, it exerts a lower pressure (assuming the amount of gas and the temperature do not change). Since P and V are inversely proportional, a graph of 1/P vs. V is linear.

According to daltons atomic theory all Adams of the same element are identical today this theory is directly refuted by the disc
Vlad [161]

Answer:

Isotopes are variations of the same atom. They have the same number of protons but have a different number of neutrons. Isotopes of the same element are not identical to each other because they have varying mass numbers. Some isotopes are radioactive because their nucleus is unstable and some isotopes are not radioactive.

How many moles of H2SO4 are present in 3.63 liters of a 0.954 M solution?
azamat
For this problem, we will use the formula setup for Molarity. 
The formula is M= moles
                               ---------
                                liters

So, lets plug in the numbers we have. We know M= 0.954, and L (liters)= 3.63. Lets plug that into our equation.
                         
                         x
         0.954= -----
                     3.63

As we can see, our moles are unknown.
So, lets multiply 0.954 times 3.63 to get our moles. 
0.954 x 3.63 equals 3.46302.

We know this is our correct answer, because when we divide 3.46302 and 3.63, we get 0.954.

Why?
Because when we divide the moles by liters, we get the molarity.

I hope I helped!!!!!

Here are some common units to know if my units confused you.
M= Molarity, which is what we find by dividing moles by liters
mol= Moles
L= Liters
