<span>Number of moles of Fe(CO)5 = mass/molar mass = (6.0 g) / (195.8955 g/mol) = 0.03 mol
Number of moles of PF3 = (4.0 g)/ (87.97 g/mol) = 0.0455 mol
Number of moles of H2 = (4.0 g) / (2.016 g/mol) = 1.984 mol
From the balanced equation
1 mol of Fe(CO)5 reacts with 2 mol of PF3 and 1 mol of H2
then 0.03 mol of Fe(CO)5 will need 0.03 (2/1) = 0.06 mol of PF3 and 0.03 mol of H2
Since we have less PF3 ( 0.0455 mol instead of 0.06 mol), that is the limiting agent</span>
Answer:
The temperature of the Nitrogen after throttling is 
Explanation:
From the question we are told that
The temperature is 
The pressure is 
The pressure after being 
Generally from the first law of thermodynamics we have that
Here 
is the change internal energy which is mathematically represented as
Here 
is the specific heat of the gas at constant pressure
is the change kinetic energy which is negligible
Q is the thermal energy which is Zero for an adiabatic process
W is the work done and the value is zero given that the gas was throttled adiabatically
So
=> 
=> 
=>
Answer:
hydrogen bond are found between nucleotides
In order for an atom to be stable it should have eight valence electrons in order to follow the octet rule the only exception to this rule is hydrogen as the maximum valence electrons it is able to hold is two
