Answer:
(1). The pressure is 533 KPa.
(2). The temperature is 406 K.
Explanation:
Given that,
Number of moles = 4.52 moles
Volume = 21.0 L
Temperature = 298 K
(1). We need to calculate the pressure
Using ideal equation of gas
Where, T = temperature
R = gas constant
V = volume
n = number of moles
Put the value into the formula
(2). Number of moles = 1.60 moles
Volume = 21.0 L
Temperature = 298 K
We need to calculate the temperature
Using ideal equation of gas
Put the value into the formula
Hence, (1). The pressure is 533 KPa.
(2). The temperature is 406 K.
Answer:
The answer to your question is letter B
Explanation:
a. [: C≡C :] This option is not correct because Carbon only has 4 valence electrons and carbons in this structure have 5, this structure does not exist.
b. [: N≡N :] This option is correct because because Nitrogen has 5 valence electrons and this structure shows that number of electrons.
c. No right choice. This option is incorrect because letter B is correct.
Answer:warm
Explanation: because it is in the southern hemisphere so in the winter while the northern hemisphere is in a cold winter the southern hemisphere is in a warm winter due to it being in the southern hemisphere where temperatures are really warm in the southern hemisphere.
