Answer:
V = 48.64 L
Explanation:
Given data:
Mass of CO₂ = 85.63 g
Temperature = 273 K
Pressure = 1 atm
Volume of CO₂ = ?
Solution:
Number of moles of CO₂:
Number of moles = mass/molar mass
Number of moles = 85.63 g / 40 g/mol
Number of moles = 2.14 mol
Volume in Litter:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
1 atm× V = 2.14 mol ×0.0821 atm.L/mol.K ×273 K
V = 48.64 atm.L / 1 atm
V = 48.64 L
ice because it can melt back to water
Correct Answer: option B. moderately polar covalent
Reason:
Both phosphorus and oxygen are non-metals, and hence they are bonded by covalent bonds. Furthermore, the electro negativity of P and O is 2.1 and 3.5 respectively. The difference in electro negativity is 1.4. Due to the difference in electro negativity, nature of the P-O bond in phosphorus pentoxide (P2O5) is moderately polar covalent.
Answer:
Most Likely A High Pressure Center
Explanation:
is most likely high pressure Center because on a weather map over the southern western Pennsylvania there's mostly high pressure over there. The descending air diverges and spreads out from the center and their is a Coriolis effect which causes the Diverging air to rotate in a clockwise direction.
Answer:
D) High temperature and little rainfall
Explanation:
The desert has sunlight and the other two don't make sense, because there is not much rainfall and the temp is high
