Under what conditions of temperature and pressure would you get the most accurate, ideal molar mass of the liquid?
Slav-nsk [51]

Answer:

High temperature and low pressure

Explanation:

At high temperature and low pressure, the molecules of the liquid do not associate to a reasonable extent.

The molecules of the liquid are somewhat separated from each other as intermolecular interactions are greatly reduced. Hence the accurate, ideal molar mass of the liquid can be measured under these conditions, hence the answer above.

kilograms represented by the mass defect for thorium -234=3.09x 10-27 kg what is the nuclear binding energy for thorium -234
Dafna1 [17]

Mass defect and binding energy are related as

ΔE = Δmc^2

Where

ΔE = binding energy

Δm = mass defect

c = speed of light

given

mass defect = 3.09x 10-27 kg

We know that speed of light = 3 X 10^8 m /s

ΔE = 3.09x 10-27 kg  (3 X 10^8 m /s)^2 = 2.781 X 10^-10 J / Kg

A. draw the structure of the tetrahedral intermediate initially formed in the reaction shown. you do not have to consider stereo
julsineya [31]
The reaction is shown below, Acid protonates the carbonyl oxygen and makes the carbonyl carbon more electrophilic. Water attacks on activated carbonyl group and forms a tetrahedral intermediate.

Intermediate:
                    Structure of Intermediate is shown both in 2-D and 3-D (below attached). 

Carbonyl group is regenerated with the elimination of ethanol.

Reaction is as below, The final product is carboxylic acid.
