I have an unknown volume of gas at a pressure of 0.5 atm and a temperature of 325k if I raise the pressure to 1.2 atm, decrease the temperature to 320k, and measures the final volume to be 48 liters what was the initial volume of the gas?
Answers
The initial volume of the gas is 117L.
What is volume?
Volume is the amount of space the matter occupies.
What do you mean by combined gas law?
- The combined gas law combines the three gas laws: Boyle's Law, Charles' Law, and Gay-Lussac's Law.
- It states that the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant.
- When Avogadro's law is added to the combined gas law, the ideal gas law results.
- It is a combination of the other gas laws that works when everything except temperature, pressure, and volume are kept constant.
- There are a couple of common equations for writing the combined gas law. The classic law relates Boyle's law and Charles' law to state:
PV/T = k
where P = pressure, V = volume, T = absolute temperature in K and k= constant.
- Another common formula for the combined gas law relates before and after conditions of a gas:
P1V1 / T1 = P2V2 / T2
Where P1 and P2 = initial and final pressure in atm
T1 and T2 = Initial and final temperature in K
V1 and V2 = initial and final volume in L
Using combined gas law:
P1V1/T1 = P2V2/T2
Given:
P1 = 0.5 atm
T1 = 325K
P2 = 1.2 atm
V2 = 48L
T2 = 320K
Assuming that the number of moles are constant for both conditions:
(P1 x V1)/T1 = (P2 x V2)/T2
Substituting the given values,
(0.5 x V1)/325 = (1.2 x 48)/320K
Solving for V1
V1 = (1.2atm x 48L x 325K)/ (320Kx 0.5 atm)
V1 = 117L
Hence, the initial volume of the gas is 117L.

Answer: The molecule identified with the letter C. HFO.
Explanation:
1) In covalent bonds, the dipolesare identified with an arrow pointing from the least electronegative element toward the most electronegative element.
2) The molecule HFO is formed by one covalent bond between H and O, and other covalent bond between F and O.
3) O is more electronegative than H, so in the H-O bond the dipole is identified with the arrow from the H atom toward the O atom. That is correctly indicated in the drawing C, in this way:
-|----→
H - O
4) F is more electronegative than O, so in the O-F bond the dipole is identified with an arrow from the O atom toward the F atom. That is correctly indicated in this way:
-|---→
O - F.

Final answer:
Water (H₂O) is an example of a covalent bond, where hydrogen and oxygen atoms share electrons to form a molecule. It is also a polar molecule and commonly acts as a solvent. Water is central in various scales of biological and environmental structures and processes.
Explanation:
Water, or H₂O, is an example of a covalent bond formation. This occurs when hydrogen and oxygen atoms join together, sharing electrons to fill their outer shells and create stability. This sharing of electrons forms a water molecule.
Furthermore, water is considered a polar molecule. Aside from covalent bonding, another characteristic of water is its ability to act as a solvent. It can dissolve gases, liquids, and solids to create different solutions, which is vital in many biological and chemical processes.
A representation of this can be seen from a hydrogen atom, to a water molecule, skin cell, liver, larger organisms like an elephant, wolf pack, up to larger ecosystems like tropical rainforests and the entire planet Earth, indicating the wide scope where water plays a crucial role.

Answers
A lack of sewage structures in overcrowded cities may lead to poor public health. Therefore, the correct option is C.
A sewage system, also known as a wastewater management system, is a system of pipes, pumping stations, and other accessories used to transport sewage from points of origin to points of treatment and disposal.
Combination sewers are systems that transport sewage from both domestic and storm sources. Due of the significant amounts of storm water that must be transported during wet weather conditions, combined sewers usually are made up of big pipes or tunnels. Public health may suffer in densely populated cities with inadequate sewage systems.
