Toluene and pyridine form ideal solutions. consider a solution of toluene and pyridine prepared at 25°c. assuming that the mole fractions of toluene and pyridine in the vapor phase are equal, calculate the composition of the solution. at 25°c the vapor pressures of toluene and pyridine are 28 and 21 torr, respectively.
in salt water solution, the salt is the solvent.
in the given molecule of 5-isopropyl-2-methyl-3-nonene their are nine carbon atom attached in straight chain.3-nonene means that double bond is between the third carbon and forth carbon atom.isopropyl group on the fifth carbon atom in the chainmethyl group on second carbon atom in the chain.
th structure of the given organic molecule is attached as an image.
answer : the correct option is, (d) 3200 joules
solution : given,
force applied = 1600 n
displacement = 2 m
formula used :
w = work done
f = applied force
d = displacement
now put all the given values in the above formula, we get the work done.
therefore, the amount of work done was, 3200 joules
answer: the state changes from liquid to gaseous state.
perfume is a mixture of aroma oils which are mixed with water or ethanol solvent. it is present in liquid state in the perfume bottle.
when the perfume is sprayed, it produces tiny droplets of water that are easily suspended in air. the tiny droplets when come in contact with the air, it easily gets evaporated and hence gets converted into gaseous state. thew particles of gaseous state have high kinetic energy with them and therefore we can easily smell it.
thus, the state changes from liquid to gaseous state.
