Answer:
Explanation:
We have the following chemical reaction:
3 HBr + Al(OH)₃ → 3 H₂O + AlBr₃
This reaction is a double-displacement reaction because the reactant exchange between themselves atoms or group of atoms. The general representation of this kind of reaction is AB + CD → AC + BD

Answer:
Solid
Explanation:
The particles in the solid matter are held close together and in fixed particles.
We can use the ideal gas law equation to find the pressure
PV = nRTwhere
P - pressure
V - volume - 2.6 x 10⁻³ m³
n - number of moles - 0.44 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 25 °C + 273 = 298 K
substituting the values into the equation,
P x 2.6 x 10⁻³ m³ = 0.44 mol x 8.314 Jmol⁻¹K⁻¹ x 298 K
P = 419 281.41 Pa
101 325 Pa is equivalent to 1 atm
Therefore 419 281.41 Pa - 1/ 101 325 x 419 281.41 = 4.13 atm
Pressure is 4.13 atm
