. A bright violet line occurs at 435.8 nm in the emission spectrum of mercury vapor. What amount of energy, in joules, must be r
Tom [10]

Answer :  The energy released by an electron in a mercury atom to produce a photon of this light must be, 4.56\times 10^{-19}J

Explanation : Given,

Wavelength = 435.8nm=435.8\times 10^{-9}m

conversion used : 1nm=10^{-9}m

Formula used :

E=h\times \nu

As, \nu=\frac{c}{\lambda}

So, E=h\times \frac{c}{\lambda}

where,

\nu = frequency

h = Planck's constant = 6.626\times 10^{-34}Js

\lambda = wavelength = 435.8\times 10^{-9}m

c = speed of light = 3\times 10^8m/s

Now put all the given values in the above formula, we get:

E=(6.626\times 10^{-34}Js)\times \frac{(3\times 10^{8}m/s)}{(435.8\times 10^{-9}m)}

E=4.56\times 10^{-19}J

Therefore, the energy released by an electron in a mercury atom to produce a photon of this light must be, 4.56\times 10^{-19}J

State and explain the trend in electronegativity values across period 3 from sodium to chlorine
muminat

The trend in electronegativity values across period 3 from sodium to chlorine is that sodium with 11 protons is the least electromagnetic element and chlorine with 17 protons is the most electronegative element.

<h3>What is electronegativity?</h3>

It should be noted that electronegativity simply means a chemical property that describes the tendency of an atom to attract elements towards it.

In this case, the trend in electronegativity values across period 3 from sodium to chlorine is that sodium with 11 protons us the least electromagnetic element and chlorine with 17 protons is the most electronegative element.

What is true of a decomposition reaction? The reactants are usually a metal and a nonmetal. The reactants are generally two ioni
melamori03 [73]

Answer

In a true decomposition reaction, the addition of energy in the form of heat or electricity is often required.

Explanation

A decomposition reaction is a chemical reaction that starts with single reactants to give new compounds as the products. These reaction requires a source of energy that could be light, heat  or electricity to facilitate the breaking-down of the chemical bonds.
