Answer:

Stars are made of gas.

Star color is related to temperature.

Explanation:

Stars are big ball of gases mainly hydrogen and helium. Stars can be bigger than sun or smaller. They appear as flat circles but are spheres. The brightness of star depends on their size and distance but not on their shape. Color of star is related to temperature. A blue color star is hotter than a yellow star. A red star is a cool star.

Express the equilibrium constant for the following reaction.P4O10(s) ↔ P4(s) + 5 O2(g)K = [P4][O2]^5/[P4O10]K = [O2]^5K = [P4O10

Answer : The correct expression for equilibrium constant will be, $K=[O_2]^5$

Explanation :

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.

As we know that the concentrations of pure solids are constant that is they do not change. Thus, they are not included in the equilibrium expression.

The given equilibrium reaction is,

$P_4O_{10}(s)\rightleftharpoons P_4(s)+5O_2(g)$
