The Density of the metal is 5.6 g/cm³
<h3>What is the density of a substance?</h3>
The density of a substance is the ratio of the mass and the volume of the substance.
The density of the metal is calculated as follows:
mass of metal = 1.4 kg = 1400 g
volume of metal = 3.2 * 17.1 * 4.6 = 251.712 cm³
Density of metal = 1400 g/251.712 cm³
Density of the metal = 5.6 g/cm³
Therefore, the density of the metal is obtained from the mass and the volume of the metal.

Answer:
1 and 2
Explanation:
Releasing some of the gas would reduce the amount of atoms inside the container therefore reducing pressure.
Cold temperature would slow down the particles in the container leading to fewer collisions per second which translates to less pressure
Answer:
Equilibrium concentration of reactants and products:
![[HI]=(0.372-2x) M =(0.372-2\times 0.03935)M =0.2933 M](https://tex.z-dn.net/?f=%5BHI%5D%3D%280.372-2x%29%20M%20%3D%280.372-2%5Ctimes%200.03935%29M%20%3D0.2933%20M)
![[H_2]=x = 0.03935 M](https://tex.z-dn.net/?f=%5BH_2%5D%3Dx%20%3D%200.03935%20M)
![[I_2]=x = 0.03935 M](https://tex.z-dn.net/?f=%5BI_2%5D%3Dx%20%3D%200.03935%20M)
Explanation:
The equilibrium constant of the reaction = 
Mole sof HI = 0.372 mol
Volume of the vessel = 1.00 L
Initial concentration of HI = 
0.372 M
At equilibrium
(0.372-2x) M x x
An expression of an equilibrium constant will be given as;
![K_c=\frac{[H_2][I_2]}{[HI]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BH_2%5D%5BI_2%5D%7D%7B%5BHI%5D%5E2%7D)
Solving for x;
x = 0.03935
Equilibrium concentration of reactants and products:
