Answer:
Acidic conditions
Explanation:
From the equations, it is clear that addition of acid favours the precipitation of calcium oxalate. As acid is added, the equilibrium position continues to shift to the far right, favouring the complete dissociation of the oxalic acid. This decreases the pH of the solution by increasing oxonium ion concentration.
Similarly, as the oxalate ion concentration increases, the precipitation of the calcium oxalate is favoured at low pH. Hence the answer.
Answer:
3.26×10⁵m³
Explanation:
Given data:
Initial volume = 3.5×10⁵ m³
Initial temperature = 27 °C (27+273= 300 K)
Initial pressure = 101 Kpa
Final volume = ?
Final temperature = -10°C (-10+273 = 263 K)
Final pressure = 95 Kpa
Solution:
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 101 Kpa × 3.5×10⁵ m³× 263 K / 300 K × 95 Kpa
V₂ = 92970.5 ×10⁵kpa. m³. K / 28500 K.Kpa
V₂ = 3.26×10⁵m³
2H2O=2H2+O2
37.4g H2O(1 mol/18.02)=2.07547 mol H2O
PV=nRT
(1.30)(V)=(2.07547)(.0821)(297)
Vwater=38.92898L
38.92898L (1 mol O2/2 mol H2O)=19.46449L O2 gas
Explanation:
Self fulfilling prophecy means how our expectations or expectations of others influence our own behavior. Being self fulfilling means, to bring about a result that has been already foretold or talked about.
