Answer: Longest wavelength - Radio wave

Shortest wavelength - Gamma wave

Explanation:

Radio waves have longer wavelengths and they have low energy in the electromagnetic spectrum. These waves have low frequency as well. Such waves are used for radio communication as they can help in transfer of signals due to longer wavelength, satellites and computer networks.

Gamma waves have shortest wavelength in the electromagnetic spectrum. They have have the highest frequencies. These are the penetrating rays and they are produced by the radioactive decay of nuclei of the atom. These waves are used for sterilization and also for disinfection.

What is the answer to...
adoni [48]

Answer: short answer short 0.65 / 5.37

15% NaOH by mass is 15g of NaOH in (100-15)g of solution.

No. Of moles of NaOH in solution = 0.65

No of moles of Water in solution = 4.72

Mole Fraction =  

(

(Moles of Solvent)

(Moles Of Solute)+(Moles of Solvent)

)

OR

(

(Moles of Solvent)

Total Number Of Moles

)

= 0.65 / 5.37

= 0.121

What is the sum of all charges in the formula for an ionic compound? +1 0 8 –1
Zarrin [17]

An ionic compound is formed between a metal and a non metal. The metal being electropositive can form a cation by transferring the electron to the electronegative non metal that gains the electrons to form an anion. Both the elements try to get a stable octet configuration by the transfer of electrons. The number of electrons lost by metal will be equal to the number of electrons gained by the non metal. Hence, the magnitude of positive charge on the cation will be equal to the magnitude of negative charge on the anion. Therefore, the overall charge on the compound will be 0

So the correct answer is the sum of all charges in the formula for an ionic compound is 0
