Answer:
Increase
Explanation:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
If the initial temperature and pressure is standard,
Pressure = 1 atm
Temperature = 273.15 K
then we increase the temperature to 400.0 K, The pressure will be,
1 atm / 273.15 K = P₂/400.0K
P₂ = 1 atm × 400.0 K / 273.15 K
P₂ = 400.0 atm. K /273.15 K
P₂ = 1.46 atm
Pressure is also increase from 1 atm to 1.46 atm.
Answer:
The answer to your question is
3KOH (aq) + FeCl₃(aq) ⇒ Fe(OH)₃ (s) + 3KCl (aq)
Explanation:
Data
Potassium hydroxide = KOH
Iron (III) chloride = FeCl₃
Iron (III) hydroxide = Fe(OH)₃
Potassium chloride = KCl
- Write the chemical equation
KOH (aq) + FeCl₃(aq) ⇒ Fe(OH)₃ (s) + KCl (aq)
Reactants Elements Products
1 K 1
1 Fe 1
3 Cl 1
1 H 3
1 O 3
This reaction is unbalanced
- Balancing the reaction
3KOH (aq) + FeCl₃(aq) ⇒ Fe(OH)₃ (s) + 3KCl (aq)
