Substance a has a specific heat that is 10 times greater than substance

Write the expression for the equilibrium constant for this reaction. 2N205(g) <==> 4N02(g) + 02(g)

Elis [28]

Answer:

K = [NO₂]⁴[O₂] / [N₂O₅]²

Explanation:

Based on the chemical equilibrium reaction:

2 N₂O₅(g) ⇄ 4NO₂(g) + O₂(g)

The equilibrium reaction is obtained as the ratio between the multiplication of the concentrations of the reactants over the products powered to its reaction coefficient. That is:

15 Which statement describes the particles of an ideal gas, based on the kinetic molecular theory?

serg [7]

Ans: (2) The gas particles have no attractive forces between them.

The kinetic theory explains the behaviour of a hypothetical ideal gas. It explains pressure in terms of the collision of gas particles against the walls of the container which it occupies.

The kinetic theory of gases is based on three main postulates:

1) The collision between gas particles is elastic i.e. no energy is lost or gained

2) The gas particles are treated as point masses i.e. the volume occupied by the gas particles is negligible when compared to the volume of the container

3) There are no attractive or repulsive forces between particles.

Why do we need to know these organic molecules? Are they important to living things?

laila [671]

Answer:

<h2>Organic molecules are important to living things because life is based on the properties of carbon. Carbon is an important element because it can </h2><h2>form four covalent bonds. ... The carbon skeletons contain the functional groups that are involved in biochemical reactions.</h2>
