A 700 mL sample of gas at STP is compressed to 300 mL, and the
1 answer:
Answer:
P₂ = 3.19 atm
Explanation:
Given data:
Initial volume = 700 mL
Initial pressure = 1 atm
Initial temperature = 273K
Final temperature =100°C (100+273= 373 K)
Final volume = 300 mL
Final pressure = ?
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₂ = P₁V₁ T₂/ T₁ V₂
P₂ = 1 atm × 700 mL × 373K / 273 K ×300 mL
P₂ = 261100 atm .mL. K /81900 K .mL
P₂ = 3.19 atm

2.67 × 10⁻²
Explanation:
Equation for the reaction is expressed as:
CaCrO₄(s) ⇄ Ca₂⁺(aq) + CrO₂⁻⁴(aq)
Given that:
Kc=7.1×10⁻⁴
Kc= ![[Ca^{2+}][CrO^{2-}_4]](https://tex.z-dn.net/?f=%5BCa%5E%7B2%2B%7D%5D%5BCrO%5E%7B2-%7D_4%5D)
Kc= [x][x]
Kc= [x²]
7.1×10⁻⁴ = [x²]
x = 
x = 0.0267
x =
