Consider the information below and answer the question that follows. An unknown compound has been found to display the following: a. Insoluble in aqueous NaHCO3.
b. Insoluble in aqueous HCl.
c. Does not give a red, blue, purple or green color upon reaction with ferric chloride.
d. There is no yellow, orange, or red solid precipitate formed in the DNP test.
e. Does not give a precipitate in Lucas Test.

Which of the following compounds best fits the unknown

Ph- CH2-CH(CH3)- OH
|
H

The compound that best fits the unknown is Compound:

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
