↪ Hello miss "galaxyu035" here's your answer for the question you wrote.
Answer :
No, <u>we cannot</u> stir silver nitrate solution with a copper spoon <u>because</u> , copper is more reactive than silver. Thus,it would displace silver from the silver nitrate solution forming copper nitrate.

Answer:
378.25°C
Explanation:
Given data:
Number of moles of gas = 0.750 mol
Volume of gas = 35.9 L
Pressure of gas = 114 KPa (114/101 = 1.125 atm)
Temperature of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
now we will put the values.
T = PV/nR
T = 1.125 atm × 35.9 L /0.750 mol × 0.0821 atm.L/ mol.K
T = 40.3875/0.062/K
T = 651.4 K
Kelvin to °C:
651.4 K - 273.15 = 378.25°C
Answer:
Hexanol has the highest boiling point.
Explanation:
Boiling points of all give compounds are as follow,
Hexanol = 157 °C
Hexanal = 129 °C
Hexanone = 128 °C
Hexane = 68 °C
Types of Interactions found in these compounds are,
Hexanol = Hydrogen Bonding & London Dispersion Forces
Hexanal = Dipole-Dipole Interactions & London Dispersion Forces
Hexanone = Dipole-Dipole Interactions & London Dispersion Forces
Hexane = Only London Dispersion Forces
Strength of Intermolecular Forces:
Hydrogen forces are stronger than Dipole-Dipole Interactions, and Dipole-Dipole Interactions are stronger than London Dispersion Forces.
Result:
Hence, due to presence of strong Hydrogen Bond Interactions Hexanol has the highest Boiling Point.
