Distillation is a widely used method for separating mixtures based on differences in the conditions required to change the phase of components of the mixture. To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points , into the gas phase .
Answer:Possibilities include balloons, popcorn, packing peanuts, wads of paper or cereal puffs. Encase the egg in any of these inside a paper or plastic bag, a sock or a stocking. If you have any bubble wrap around the house, wrapping the egg in several layers of bubble wrap should also provide a good cushion
Explanation:
Answer:
The most appropriate structure given the sparse spectral data is<u><em> 4-acetyl benzoic acid (see attached).</em></u>
Explanation:
It is difficult to accurately elucidate the structure of this compound without its chemical formula. But from the 1H NMR spectral data shows a total of 8 hydrogen atoms:
- 12.71 (1H. s) - confirms presence of carboxylic acid proton, C=O-OH
- 8.04 (2H, d) - confirms aromatic hydrogen
- 7.30 (2H, d) - confirms aromatic hydrogen
- 2.41 (3H,s) - confirms C=C hydrogen or ketone O=C-RCH3
The attached files show the structure and the neighboring hydrogen atoms.
<u>The most likely structure i 4-acetyl benzoic acid</u>
Answer:
6. Double replacement "DR"
7. Double replacement "DR"
8. Combustion "C"
9. Single replacement "SR"
10. Decomposition "D"
Explanation:
- number 6 and 7 are double replacements because if you look at the compounds in the reactants vs the products, it is evident that there has been a replacement between Na & K in number 6 and Mg & Li in number 7, a "DR" occurs when the anions and cations in 2 molecules switch places to form 2 new compounds.
- number 8 is a combustion reaction because a combustion reaction occurs when oxygen is combined with another compound to form water and carbon dioxide (H2O & CO2).
- number 9 is a single replacement reaction because the Pb and Fe have simply switched places, "SR" are when an element trades with another to form a new compound and the element that was swapped.
- number 10 is a decomposition because it can be observed that the compound in the products is being broken down into the molecules or compounds that it is made up of, started with one and finished with 2
