Answer:
Explanation:
1. Temperature of the bottle when only helium gas was present :T
P= 1.83 atm
V = 2.50 L
n = 0.458 moles
Using an Ideal gas equation:
PV=nRT
T= PV/nR= 1.83*2.50/0.458* 0.0821 =121.81K
2. Temperature of the bottle when argon gas is added into the container:T'
P' =2.05 atm
V = 2.50 L
n' = 0.458 mol + 0.713 mol = 1.171 mol
PV=nRT
T= PV/nR = 1.83*2.50/1.171*0.0802 = 53.37
The change in temperature will be
Final temperature = Initial temperature:T' - T
53.37 k - 121.81 K = -68.44 K
The change in temperature of the gas mixture is -68.44 K.
Answer:
Explanation:
Causes of Greenhouse Effect
- Burning of Fossil Fuels. Fossil fuels are an important part of our lives.
- Deforestation. Plants and trees take in carbon dioxide and release oxygen.
- Industrial Waste and Landfills.
- Depletion of Ozone Layer.
- Acidification of Water Bodies.
Answer:
NaF and KBr
Explanation:
These two substances contain pure ionic bonds. LiI is a covalent compound because of the Large polarizing power of Li and the high polarizability of I(Fajan's rules). The other compounds mentioned are organic compounds. They are not soluble in water at all.
Answer: Mercury!!!!!!
Explanation:
Highs and lows. Orbiting between 28 and 43 million miles (46 and 70 million kilometers) from the sun, Mercury, also the smallest planet, feels the brunt of the solar rays. According to NASA, the tiny world suffers the most extreme temperature range of any other planet in the solar system.
Have great day!
