2 mol of Sodium hydroxide (NaOH) reacts to form 1 mol of sodium sulfate (Na_2SO_4)
- 1 mol of NaOH produces 1/2 mol sodium sulfate.
3.7moles of Na OH produces
- 1/2(3.7)=1.8mol sodium sulfate
Answer:
The last figure (with the name 3-Chloro-2-iodo-4-methylhexane) is correct.
Explanation:
---> It gives the correct numbering of the positions of each Iodine Chlorine and Methyl which are attached at 2, 3 and 4 respectively
---> and also the names are given on alphabetical order (i.e. first Chlorine then Iodine and then Methyl)
The gas in question must be neon.
<h3>What is the leaking gas?</h3>
The spectrum can be used to identify a gas. The idea of a spectrum is adapted from the Bohr model of the atom. It stems from the change in the energy level of an electron in the atom.
The gases that could be used in a bulb are; hydrogen, Helium, Neon, Argon, Krypton, Xenon. If we look at the attached chart that shows the maximum wavelength of each gas, we will notice that that of neon is fairly constant and it has the highest number of lines in the spectrum.
Based on the strength of the all the evidences as shown above, the gas in question must be neon.
