Answer:

A displacement reaction

Explanation:

This is because the chlorine reacts with the sodium bromide, forcing it to go brown.

I hope this helps, good luck! (✿◡‿◡)

When chlorine is added to a solution of sodium bromide (either as a gas or dissolved in water), the bromine is replaced by the chlorine.

In chemistry, a solution is a homogeneous mixture of two or more compounds in their relative proportions that can be continually altered up to what is referred to as the limit of solubility.

Although the word "solution" is typically used to refer to the liquid state of matter, solutions of gases and solids are also possible.

When chlorine is added to a solution of sodium bromide (either as a gas or dissolved in water), the bromine is replaced by the chlorine. Because chlorine is more reactive than bromine, sodium bromide loses its bromine content. The mixture darkens to brown. The bromine has been displace, giving this colour of brown.

The pressure of the gas = 40 atm

Given

200 ml container

P = 2 atm

final volume = 10 ml

Required

Final pressure

Solution

Boyle's Law  

At a fixed temperature, the gas volume is inversely proportional to the pressure applied  

[tex]\tt \rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]

Input the value :

P₂ = P₁V₁/V₂

P₂ = 2 x 200 / 10

P₂ = 40 atm

Moles of NH3 = 0.3 moles

N2 + 3H2 → 2NH3

4.2021 g of N2

Required

moles of NH3

Solution

mol N2 :

= 4.2021 g : 28 g/mol

= 0.15

From the equation, mol NH3 :

= 2/1 x mol N2

= 2/1 x 0.15

= 0.3 moles

K= 325.15

Answer:

Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.

In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them

Explanation:

The final temperature : T₂ = 680.625 K

Given

V₁=240 ml

T₁ = 90 + 273 = 363 K

V₂ = 450 ml

Required

The final temperature

Solution

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

Input the value :

T₂ = V₂T₁/V₁

T₂ = 450 x 363 / 240

T₂ = 680.625 K

The volume of dry gas = 168 L

Given

175 ml container at 15°C

P total = 752 torr

water vapour = 12.8 torr

Required

The volume of dry gas

Solution

Dalton's law of partial pressure :

P tot = P₁ + P₂ + P₃ ....  

P total = P O2 + P water

P O2 = 752 - 12.8

P O2 = 739.2 torr

Boyle's Law  

At a fixed temperature, the gas volume is inversely proportional to the pressure applied  

P₁V₁ = P₂V₂

739.2 175 = 770 .V₂

V₂ = 168 L
