Answer:

a mixture

Explanation:

A mixture is a material made up of two or more components joined together, but not chemically combined. In a mixture, a chemical reaction does not occur and each of its components maintains its identity and chemical properties.

A compound is a substance formed by the chemical combination of two or more different elements from the periodic table. The elements of a compound cannot be divided or separated by physical processes. They are not mixtures or alloys

An element is a type of matter made up of atoms of the same class.  It is an atom with unique physical characteristics, that substance that cannot be decomposed by a chemical reaction.

physical, mathematical, and conceptual are the 3 types of models an example of a conceptual model is a model of our solar system or even a rocket a limitation of them is they are not realistic in scale but allow us see arrangements of things. mathematical models could be something like a formula graph charts ect we benefit from the visual steps however the downfall is there's lots of user error and a physical model is something like an atom model it allows to see the thing but it's physical states limits us

What is Δn for the following equation in relating Kc to Kp?CH4(g) + H2O(g) ↔ CO(g) + 3 H2(g)-120-3-2
Sindrei [870]

Answer: Δn for the following equation in relating Kc to Kp is 2.

Explanation:

The balanced chemical equation is:

CH_4(g)+H_2O(g)\rightleftharpoons CO(g)+3H_2(g)

Relation of K_p with K_c is given by the formula:

K_p=K_c(RT)^{\Delta n_g}

Where,

K_p = equilibrium constant in terms of partial pressure

K_c = equilibrium constant in terms of concentration

R = Gas constant

T = temperature

\Delta n_g = change in number of moles of gas particles = n_{products}-n_{reactants}=4-2=2

Putting values in above equation, we get:

K_p=K_c\times (RT)^{2}

Thus the value of Δn for the following equation in relating Kc to Kp is 2.
