Answer:
Slide a magnet through the mixture. When you take the magnet off, the iron filings are going to be attracted to the magnet and the sand will stay in the bowl
Explanation:
Im not really sure but i think its A.<span>It explains the data that relates to the specific problem.</span>
<span>From Graham's law of diffusion.
Rate of diffusion of Neon/Rate of diffusion of Bromine =âš(Molar mass of bromine gas/Molar mass of Neon) Molar mass of bromine gas =79.904 and Molar mass of Neon = 20.17. So we have. âš(79.904/20.17) from the right hand side of the equation. Hence it follows that.
Rate of diffusion of Neon/Rate of diffusion of Bromine = âš3.96 = 1.98. Hence it follows that Rate of Diffusion of Neon is 1.98 or (2 times, to1d.p) the rate of diffusion of Bromine.</span>
The first step is to focus on the parent carbon chain:nonane. This indicates a carbon chain with 9 carbon atoms. From here, on the 4th carbon from one side, place a Br functional group; on the 2nd carbon, place a I functional group; on the 5th and 6th carbon, place a CH₃ (methyl) functional group to each. Lastly, complete the bonding with H atoms. The structure is shown in the attached picture.
