Answer: I think the answer is C
Explanation:
Answer:
Saturated solution
Explanation:
Saturated solution is the solution in which no more solute can be dissolved at a particular temperature.
A amount of the solute, potassium nitrate is dissolved at elevated temperature and on cooling, it precipitates. It means that the solution is saturated at that temperature. <u>Precipitation of the solute at lower temperature indicates that the solution is saturated solution.</u>
Answer:
Change occur in heat energy.
Explanation:
Change occur in the heat energy of molecules during condensation process. The molecules of gas releases its heat energy and converted into liquid state. With this heat energy, they are active and escape from each other but when the heat energy is removed from them, the attractive forces between these gas molecules are formed which convert them into liquid state so change in heat energy occur in the condensation process.
Answer: Thus 0.724 mol of 
are needed to obtain 18.6 g of 
Explanation:
To calculate the moles :
According to stoichiometry :
2 moles of are produced by = 1 mole of
Thus 1.09 moles of will be produced by =
of
But as yield of reaction is 75.6 %, the amount of needed is =
Thus 0.724 mol of are needed to obtain 18.6 g of
