The total pressure inside a 1.62 cylinder kept at 35°C is 1.15 atm. If the volume of the cylinder drops to 0.74 L and the temperature remains the same, what is the new pressure inside the cylinder?
B. phosphorous (P)
C. sulfur (S)
D. oxygen (O)
Answers
Answer: Phosphorous
Explanation: Nitrogen(N): 7:
Phosphorus(P): 15:
Oxygen(O): 8:
Sulphur(S): 16:
As nitrogen contains half filled configuration, it is stable and does not react. Phosphorous lies below nitrogen and reactivity decreases down a group for non metals as they tend to gain electrons as the valence shell move away from the nucleus.
Oxygen has 4 valence electrons, thus it need to gain two electrons to attain stable configuration. Thus is reactive.
Sulphur lies below oxygen and also need to gain two electrons. Reactivity decreases down a group for non metals as they tend to gain electrons as the valence shell move away from the nucleus.
b. .78 M
c. 3.85 M
b. 4.98 M
Answers
Answer:
The correct answer is c.
Explanation:
First, look for the same problem to verify that the correct volume is 0.702 L.
Now we must calculate the amount of glucose moles (n) in the 500g:
n =
n = 2,7 mol
Molarity is given by moles of compound per liter. In this way, we calculate the molarity (M) as:
M =
M =
Have a nice day!
500 / 180.16 => 2.775 moles
Volume = 0.72 L
M = n / V
M = 2.775 / 0.72
M = 3.85 M
