You want to convert nm to m.

1.00 x 10^-3 nm=1.00 x 10^-12 m

Use both equations: E=hν and c=λν

Use the second equation to find the frequency so you can plug it into the energy equation.

c=λν

(3.00 x 10^8 m/s)=(1.00 x 10^-12 m)ν

Rearrange to solve for ν:

(3.00 x 10^8 m/s)/(1.00 x 10^-12 m)=ν

3.00 x 10^-20 Hz=ν

Use 1st equation to find the energy:

E=hν

E=(6.626 x 10^-34 J*s)(3.00 x 10^-20 Hz)

E=1.99 x 10-13 J

If a sample of cork has a mass of 2.88 g and a volume of 12.0 mL, what is the density of the cork? Show your work.
PilotLPTM [1.2K]

Answer:

The answer is

<h2>0.24 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

<h3>density =  \frac{mass}{volume}</h3>

From the question

mass of cork = 2.88 g

volume = 12 mL

The density is

density = \frac{2.88}{12}

We have the final answer as

0.24 g/mL

Hope this helps you

The product of a Lewis acid-base reaction is a(n) __________, a single species that contains a new covalent bond. The Lewis acid
andreyandreev [35.5K]

Answer:

Adduct, donate, accept

Explanation:

Lewis acids are those having suitable vacant orbital for electron acceptance and forming a covalent bond with an electron rich species. Example: BCl_{3} (B has vacant 2p orbital for electron acceptance)

Lewis bases are those having energetically available unshared electrons that can be donated to an electron deficient species and form a covalent bond. Example: NH_{3} (N has energetically available lone pair)

So, product of Lewis acid-base reaction is an adduct (BCl_{3}-NH_{3}) where a new covalent bond is formed between B and N.

Calculate the vapor pressure of spherical water droplets of radius (a) 17 nm and (b) 2.0 μm surrounded by water vapor at 298 K.
Montano1993 [528]

Explanation:

Relation between pressure of water and its droplet is as follows.

           ln (\frac{p}{p_{o}}) = \frac{2 \gamma M}{r \rho RT}

where,   p = pressure of droplet

          p_{o} = water pressure in given temperature

          \gamma = 7.99 \times 10^{-3}

           M = Molecular Weight in Kg/Mol (0.018 for water)

            r = radius in meters

     \rho = density of water in Kg/m^{3} (1000 kg/m^{3})

           R = ideal gas constant (8.31)

           T = temperature in Kelvin

(a)   We will calculate the value of p as follows.

           p = e^{\frac{2 \gamma M}{r \rho RT}} \times p_{o}

              = e^{\frac{2 \times 0.07199 \times 0.018}{1.7 \times 10^{-8} \times 1000 \times 8.31 \times 298 K} \times 25.2

              = 26.8 torr

(b)  And, vapor pressure of spherical water droplets of radius 2.0 \mu m or 2 \times 10^{-6} m

             p = e^{\frac{2 \gamma M}{r \rho RT}} \times p_{o}

              = e^{\frac{2 \times 0.07199 \times 0.018}{2 \times 10^{-6} \times 1000 \times 8.31 \times 298 K} \times 25.2

              = 25.2 torr
