Is it multiple choice or anwser or each question
Show the two (neutral) organic starting materials that would be used to synthesize the following ketone by a hydroxide mediated crossed‑aldol reaction the product formed is alpha-beta unsaturated carbonyl compound.
<h3>What is the Aldol-condensation ?</h3>
The condensation response among distinctive molecules of an aldehyde or ketone in a protic solvent which includes water or alcohol constitutes the crossed aldol response. When condensation is among distinctive carbonyl compounds, it's far referred to as crossed aldol condensation.
Applying the retrosynthetic evaluation technique, the systems of the beginning substances are decided via way of means of the usage of the bottom catalyzed for the crossed aldol mechanism. The beginning substances are aldehyde and ketone compounds that react with every different to present the goal molecule.

Answer:44.01% of the spheres are copper
Explanation:
mass Cu + mass Pb = 4.35kg = 4.35 x 1000 = 4350g
But
Volume= mass / density
Let the volume of copper be C
density of Cu = 8.94 g/cm^3
Mass of copper = 8.94C
Let the volume of Lead be L
density of lead = 11.34g/cm^3
Mass of lead = 11.34L
Since
mass Cu + mass Pb = 4350kg
therefore
8.94C + 11.34L = 4350g----- EQN A
also
volume of copper + volume of lead = 423 cm^3
Volume of Lead ,L=423-C
putting the value of C = 423-L in Equation A becomes
8.94C + 11.34L = 4350g
8.94C + 11.34(423-C)= 4350g
8.94C+ 4796.82-11.34C=4350
4796.82-4350=11.34C- 8.94
446.82=2.4C
C= 186.175
Volume of copper = 186.175cm^3
Percentage copper = volume copper / total volume metal x 100/1
= 186.175 cm^3 / 423 cm^3 x 100/1
= 44.01%
Answer:
13.45 grams of NaCl will be produced
Explanation:
Given:
Mass of CuCl2 = 15 grams
Molar mass of CuCl2 = 134.5 g/mol
Mass of Na(NO3) = 20grams
Molar mass of Na(NO3) = 85 g/mol
To find:
Amount of Sodium chloride produced = ?
Solution:
<u>No of moles of CuCl2 = 15/134.5 = 0.11 moles</u>
<u>No of moles of Na(NO3) = </u><u>2</u><u>0</u><u>/</u><u>8</u><u>5</u><u> </u><u>=</u><u> </u><u>0.23 moles,</u>
<em><u>1CuCl2 + 2Na(NO3) --> 1Cu(NO3)2 + 2NaCl</u></em>
from the reaction, 1 mole of copper chloride reacts with 2 mole of NaNO3 to produce 2 moles of sodium chloride.
Hence, 0.11 mole of copper chloride will react with 0.23 mole of NaNO3 to produce 0.23 moles of sodium chloride.
Mass of 0.23 moles of NaCl = 0.23 × M.M of NaCl
<em><u>(Molar mass of NaCl = 58.5)</u></em>
Mass of 0.23 moles of NaCl = 0.23 × 58.5 = 13.45 grams
