Answer: The overall chemical reaction is exothermic is the correct statement.
Explanation: As seen from the given image, the reactants are at higher energy level and products are at lower energy level and the excess energy is released in the form of heat. These reactions are considered as exothermic reactions.
Hence, the reaction given in the image is an exothermic reaction.
Explanation:
It is known that relation between wavelength and frequency is as follows.
where, 
= wavelength
c = speed of light = 
[/tex]\nu[/tex] = frequency
It is given that frequency is 
. Hence, putting this value into the above formula and calculate the wavelength as follows.
= 
or, = 
Thus, we can conclude that wavelength of given radiation is .
Each period in the periodic table corresponds to a principal energy level
Pollution and people littering. Can change everything.
Atomic number refers to the proton number of the atom itself. Number of electrons in an atom (an atom that is not reacted with any other molecules / Just the atom alone), is the same as the number of protons, because each electron has 1 negative charge, and each proton 1 positive charge, where they cancel out on each other to become a neutral charge.
So, when atomic number is 6, proton number is also 6, and number of electrons will also be 6 in that atom.
Hope this helps! :)
