Explanation:
your answer is Kelvin because it is the SI unit of temperature
Answer:
Solid : The intermolecular space is very less
Liquid : The intermolecular space is fairly more than in solids
Solid : It has a fixed shape
Liquid : It has a fixed volume but shape changes according to where it is placed
Solid : eg : Books
Liquid : eg : water

Answer:
5.6 seconds
Explanation:
The reaction follows a zero-order in dinitrogen monoxide
Rate = k[N20]^0 = change in concentration/time
[N20]^0 = 1
Time = change in concentration of N2O/k
Initial number of moles of N2O = 300 mmol = 300/1000 = 0.3 mol
Initial concentration = moles/volume = 0.3/4 = 0.075
Number of moles after t seconds = 150 mmol = 150/1000 = 0.15 mol
Concentration after t seconds = 0.15/4 = 0.0375 M
Change in concentration of N2O = 0.075 - 0.0375 = 0.0375 M
k = 0.0067 M/s
Time = 0.0375/0.0067 = 5.6 s
