AnnyKZ [126]3 years ago
4 0

Answer:

\huge{3.783 \times  {10}^{ - 19}  \: J}

Explanation:

The energy of the wave can be found by using the formula

<h3>E = hf</h3>

where

E is the energy

f is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question we have

E = 6.626 × 10-³⁴ × 5.71 × 10¹³

We have the final answer as

3.783 \times  {10}^{ - 19}  \: J

Hope this helps you

How do electrons in a metallic bond behave?
igomit [66]

Hello,

In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.

Hope this helps!!!! Happy Holidays!!!! (:

1) (C2H5)2CBrCH2CH3 is the answer

explaiation:-

so when HBr is added to an alkene , according to the Markonicoff's rule ...H atoms are bonded to the C containing the most amount of H and Br is added to the other C.

2) Just add alkoholic KOH∆

What makes a charged object attract an uncharged object?
Ratling [72]

Answer:

its c I think C)

 

The reason for this is due to the phenomenon called "Charging by Induction". What that means is that when something with a charge, for example a negative charge, is brought near an uncharged one, it induces the opposite charge onto it (positive in this case) and therefore since opposites attract, it attracts it.

The reason for this is that since, just like a positive magnet rejects and pushed away like charges, the electrons hold a negative charge, they push away any electrons that may be in the neutrally charged item causing only protons to be left, thus creating an oppositely charged object. Or vice versa.

So whatever charge the object has, it induces the opposite charge into the uncharged object, causing the charges to move only in the uncharged one.

The solubility of nitrogen gas at 25 ◦C and 1 atm is 6.8×10−4 mol/L. If the partial pressure of nitrogen gas in air is 0.76 atm,
iris [78.8K]

Answer:

Concentration of dissolved nitrogen = 5.2 × 10⁻⁴ mol/L

Explanation:

More the pressure of the gas, more will be its solubility.

So, for two different pressure, the relation between them is shown below as:-

\frac {P_1}{C_1}=\frac {P_2}{C_2}

Given ,  

P₁ = 1 atm

P₂ = 0.76 atm

C₁ = 6.8 × 10⁻⁴ mol/L

C₂ = ?

Using above equation as:

\frac{1\ atm}{6.8\times 10^{-4}\ mol/L}=\frac{0.76\ atm}{C_2}

C_2=\frac{0.76\times 6.8\times 10^{-4}}{1}\ mol/L

<u>Concentration of dissolved nitrogen = 5.2 × 10⁻⁴ mol/L</u>
