The density of wax is <u>much higher</u> than the density of air because they are rigid and denser.

<h3>What is Density? </h3>

<em>Density </em>is defined as the mass of a unit volume of a material substance.

It is given by the formula,

Density = Mass / Volume

The units of density are g/cm³, kg/m³ etc.

Gases are not as dense compared to solids. This is because the particles in <u>solids</u> are very close to each other and the intermolecular gaps are very less. This makes them rigid and dense.

Thus, solids are denser than gases.

Wax is a solid and air is gas.

Hence, the density of wax is <u>much higher</u> than the density of air

The density of wax much higher than the density of air because of its more mass.

<h3>Why is the density of wax much higher than the density of air?</h3>

The density of wax is much higher than the density of air because of its state of matter. We know that wax is a solid substance whereas air is a gaseous substance and we also know that solid substance is heavier than gas so wax has higher density as compared to air.

So we can conclude that the density of wax much higher than the density of air because of its more mass.

The balanced reaction is 3 Ca ( s ) + N 2 ( g )  →  Ca 3 N 2 ( s ).

<u>Explanation</u>:

A chemical equation is said to be balanced when the total number of atoms present on the reactants side is equal to the total number of atoms present on the product side.

The unbalanced chemical equation is as follows,

                             Ca ( s ) + N 2 ( g )  →  Ca 3 N 2 ( s )

To balance this equation, you need to look at how many atoms of each element are present on each side of the chemical equation.

 Calcium has  1  atom on the reactant and  3  on the products side. To balance the reaction we need to multiply the calcium atom by  3  on the reactants side.

                            3 Ca ( s ) + N 2 ( g )  →  Ca 3 N 2 ( s )    

Now  Nitrogen has a coefficient of  2  on both sides of the reaction. Hence the balanced chemical equation will thus be

                              3 Ca ( s ) + N 2 ( g )  →  Ca 3 N 2 ( s )

Consider the reaction: P(s) + 5/2 Cl2(g)PCl5(g) Write the equilibrium constant for this reaction in terms of the equilibrium con
Pani-rosa [81]

Answer: The equilibrium constant for the overall reaction is K_a\times K_b

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios.

a) P(s)+\frac{3}{2}Cl_2(g)\rightarrow PCl_3(g)

K_a=\frac{[PCl_3]}{[Cl_2]^{\frac{3}{2}}}

b) PCl_3(g)+Cl_2(g)\rightarrow PCl_5(g)

K_b=\frac{[PCl_5]}{[Cl_2]\times [PCl_3]}

For overall reaction on adding a and b we get c

c) P(s)+\frac{5}{2}Cl_2(g)\rightarrow PCl_5(g)

K_c=\frac{[PCl_5]}{[Cl_2]^\frac{5}{2}}

K_c=K_a\times K_b=\frac{[PCl_3]}{[Cl_2]^{\frac{3}{2}}}\times \frac{[PCl_5]}{[Cl_2]\times [PCl_3]}

The equilibrium constant for the overall reaction is K_a\times K_b
