For Single Element Ions (e.g. K+ , Mg2+, P3-) To name positive (+) ions write the name as from the Periodic Table and add the word 'ion' afterwards. To name negative (-) ions write the name from the Periodic Table but replace the ending with 'ide'. Put the word 'ion' after the name.

4) convert moles of C₄H₁₀ to mass
= 23.7 grams of C₄H₁₀ is needed to produce 71.9 grams of CO₂
Answer:
Gamma range
Explanation:
A very intense start is a bright star at very high temperature. Now, hotter the object shorter is the wavelength of peak radiation. The increasing order of wavelength of the given regions in the electromagnetic spectrum are:
gamma range < ultra violet < visible < infrared
Ideally, since the shortest wavelength based on the given options is the gamma range, the peak intensity can also be expected to fall at that wavelength. If the star spectrum was recorded in the UV-visible range of the EM spectrum, then it would fall in the UV range
Mass spectrum of Dodecane will give following information.
1 ) Molecular Peak or Parent Peak:
The Parent peak will appear at m/z = 170. The intensity of this peak will be very weak.
2) Fragments:
Usually the fragments of such long chain alkanes appear with spacing of 14 amu, Hence, the peaks in dodecane will be as follow,
170 - 156 - 142 - 128 - 114 - 100 - 86 - 72 - 58 - 44 - 30 - 16
3) Base Peak:
Most probably the Base peak will appear at m/z = 57. This peak is due to the formation of tertiary butyl cation as the intensity mainly depends upon the stability of cation. So this cation might form due to rearrangment giving the intensity of 100%.
