Answer:

Explained below

Explanation:

1) Hydrogen bonds are formed between molecules

All these is because the bonds are flexible in such a manner that in the liquid phase, the molecules are relatively close to each other.

However, it is also noted that the hexagonal arrangement of ice is formed the bonds will be locked in place which will result in the average distance between molecules actually increasing which in turn means given a result that ice is less dense than liquid water.

B) Water possesses a high boiling point: This is because the Hydrogen oxygen bond or O-H bonds are highly polar and the Hydrogen atoms in this bond are located at two corners of the tetrahedron shaped like bond shape which gives water it's high molecular polarity in which in turn makes the molecules to stick together.

The equilibrium constant Kc for the reaction below is 0.00584 at a certain temperature. Br2(g) ⇌ 2Br(g) If the initial concentra
Vinil7 [7]

Answer:

Explanation:

Given that:

The chemical equation for the reaction is:

             Br2(g)    ⇌  2Br(g)

Initially  0.0345M  0.0416M

Q_C = \dfrac{[Br]^2}{[Br_2]} = \dfrac{(0.0416)^2}{(0.0345)}= 0.05016

Q_C =0.05016 >>> K_c(0.00584)

Thus, the given reaction will proceed in the  backward direction

 The I.C.E table is as follows:

                       Br2(g)    ⇌  2Br(g)

I               0.0345                 0.0416

C                 +x                        -2x

E             (0.0345+x)            (0.0416 -2x)

K_c = \dfrac{[Br]^2}{[Br_2]} = \dfrac{(0.0416-2x)^2}{(0.0345+x)} = 0.00584

= 0.00173056 - 0.0832x - 0.0832x + 4x² = 0.00584 (0.0345 +x)

= 0.00173056 - 0.166x + 4x² = 2.0148× 10⁻⁴ + 0.00584x

= 0.00173056 - 2.0148× 10⁻⁴ - 0.166x - 0.00584x + 4x²

= 0.00152908  - 0.17184x + 4x²

Solving by using Quadratic formula

x = 0.03038 or 0.0126

For x = 0.03038

At equilibrium

[Br₂] = (0.0345 + 0.03038) = 0.06488 M

[Br] =  (0.0416 -2(0.03038)) = - 0.01916 M

Since we have a negative value for [Br], we discard the value for x

For x = 0.0126

At equilibrium

[Br₂] = (0.0345 + 0.0126) = 0.0471 M

[Br] =  (0.0416 -2(0.0126)) = 0.0164 M

Which of the following will stay constant, no matter if the substance is in the solid, liquid, or gas state?
34kurt
The mass of any substance will remain the same regardless of its state of matter. Using water as an example, its volume increases when it is boiled to a gas or when it is frozen from a liquid state to the solid state ice. The volume and temperature will change as it moves through the states of matter, however the amount of individual molecules of oxygen and hydrogen that form water will remain the same and this constitute mass.
