Answer : The energy change occurring in the atom due to this emission is, 18.38\times 10^{-26}J

Solution :

Formula used :

\Delta E=\frac{h\times c}{\lambda}

where,

\Delta E = change in energy of photon = ?

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

c = speed of light = 2.998\times 10^8m/s

\lambda = wavelength = 1.08 m

Now put all the given values in the above formula, we get the energy of the photons.

\Delta E=\frac{(6.626\times 10^{-34}Js)\times (2.998\times 10^8m/s)}{1.08m}

\Delta E=18.39\times 10^{-26}J

Therefore, the energy change occurring in the atom due to this emission is, 18.38\times 10^{-26}J

How many isomers does propane have?<br> 01<br> 02<br> 03<br> 05
Irina18 [472]

Answer:

A.) 1

Explanation:

Propane only exists in one conformation. It does not have enough carbons to form branches, and there are only hydrogens attached to each carbon. Furthermore, there is no way to twist the carbon or change its orientation (ex. cis- and trans-) to result in a different structure of propane. There is no other way to represent the molecule without drawing a different molecule.

Which atom gives up its electrons most easily?<br><br> THE ANSWER IS “Rb”
Sedbober [7]

Answer:

cesium

In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li). In fact, for the alkali metals (the elements in Group 1), the ease of giving up an electron varies as follows: Cs > Rb > K > Na > Li with Cs the most likely, and Li the least likely, to lose an electron

Write 2,469,100 in Engineering Notation with 3 significant figures.
Gala2k [10]

Answer: 2.47\times 10^{6}

Explanation:

Engineering notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form times 10 raise to the power.  It is similar to the scientific notation but in engineering notation, the powers of ten are always multiples of 3.

The engineering notation written in the form:

a\times 10^b

where,

a = the number which is greater than 0 and less than 999

b = an integer multiple of 3

Now converting the given value of 2,469,100 into engineering notation, we get 2.47\times 10^{6}

Hence, the correct answer is, 2.47\times 10^{6}

The element carbon (C) is most likely to form covalent bonds with the element
pochemuha
<span>Carbon (C) is most likely to form covalent bonds with Beryllium (Be) or Sodium (Na) because they are both metals and covalent bonds are metals that share their valence electrons with the gases / non-metals to get to the stable octet. Krypton is a gas and Selenium is a metalloid</span>
