Answer:
Step 1) hydrolysis using NaOH/H2O to form benzylalcohol
Step2) oxidation to Carboxylic acid using KMnO4 followed by decarboxylation to form benzene
3) friedel craft acylation using CH3COCl/AlCl3
Explanation:
The above 3 steps will yield acetophenone from methylbenzoate
ºC = K - 273
ºC = 96 - 273
= -177ºC
answer A

<h3>
Answer:</h3>
812 kPa
<h3>
Explanation:</h3>
- According to Boyle's law pressure and volume of a fixed mass are inversely proportional at constant absolute temperature.
- Mathematically,
At varying pressure and volume;
P1V1=P2V2
In this case;
Initial volume, V1 = 2.0 L
Initial pressure, P1 = 101.5 kPa
Final volume, V1 = 0.25 L
We are required to determine the new pressure;
Replacing the known variables with the values;
= 812 kPa
Thus, the pressure of air inside the balloon after squeezing is 812 kPa
Answer:
metallic bonding is the bond form between two or more metal elements or between metal element and the other group elements
Answer:
C. C
Explanation:
The heating curve is a graphical representation shows that how different phases of substances change as it is influenced by the increase in temperature or heat.
Section A represents solid phase, Section B represents solid-liquid phase, section C represents liquid phase, section D represent liquid-gas phase and section E represents gas phase.
Section C of the graph shows the liquid phase of the substance gaining kinetic energy. During Phase C, heat energy is absorbed and liquid particles gain kinetic energy to change into gas form that is section E.
Hence, the correct option is C.C.
