Covalent bonds occur when two atoms share electrons. The structure that takes place is the outer shell and the carbon atoms
Answer:
P₁ = 2.82 atm
Explanation:
Given data:
Initial volume = 28 L
Initial pressure = ?
Initial temperature = 65 °C (65 +273.15 = 338.15 K)
Final temperature = 35 °C (35 +273.15 = 308.15 K)
Final volume = 36 L
Final pressure = 2.0 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = P₂V₂T₁/T₂ V₁
P₁ = 2.0 atm × 36 L × 338.15 K / 308.15 K × 28 L
P₁ = 24346.8 atm .L. K / 8628.2 K.L
P₁ = 2.82 atm
Answer:
8.33 atm
Explanation:
Xe is 5 out of (4+5) or 5 / 9 ths of the gas present
5/9 * 15 atm = 8.33 atm
Answer: D
Explanation: Even if the audiance did not have a pair of shoes felt uncomfortable or worried not a lot of people would have noticed. If anyone noticed it would only be about 5% of people so that is how I came to the conclision of D.
