Astronauts brought back 500 lb of rock samples from the moon. How many kilograms did they bring back? (1 kg = 2.20 lb)
A. 500 kg
B. 1,100 kg
C. 498 kg
D. 227 kg
I believe it is D.
Answer:a. 1-propanol,
Explanation:
Boiling point depends on the relative molecular mass of the compound and the kind of intermolecular interactions present in the substance. 1-propanol has a relative molecular mass of 60 and posses strong intermolecular hydrogen bonding. The presence of hydrogen bonding is known to lead to an increase in boiling point. As a result of this, it is obvious that 1-propanol has the highest boiling point among other compounds in the list.

Answer:
, Kp = 0.08967
, Kp = 2.3×10³⁰
Explanation:
The relation between Kp and Kc is given below:

Where,
Kp is the pressure equilibrium constant
Kc is the molar equilibrium constant
R is gas constant
T is the temperature in Kelvins
Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)
For the first equilibrium reaction:

Given: Kc = 2.2
Temperature = 299 K
R = 0.082057 L atm.mol⁻¹K⁻¹
Δn = (2)-(2+1) = -1
Thus, Kp is:

<u>Kp = 0.08967 </u>
For the second equilibrium reaction:

Given: Kc = 2.3×10³⁰
Temperature = 299 K
R = 0.082057 L atm.mol⁻¹K⁻¹
Δn = (2)-(2) = 0
Thus, Kp is:

<u>Kp = 2.3×10³⁰</u>
