Answer:

They indicate the number of each chemical species that reacts or is formed. Methane and oxygen (oxygen is a diatomic — two-atom — element) are the reactants, while carbon dioxide and water are the products. All the reactants and products are gases (indicated by the g's in parentheses).

What do we mean by atmospheric pressure

olasank [31]

Answer:

ExplanationImage

Atmospheric Pressure is the force per unit area exerted on a surface due to the weight of air molecules above it. It is caused by the collisions of the air molecules with that surface.:

What are the Characteristics you would look for to identify plasma substance

Vinil7 [7]

Plasma has similar physical characteristics to gas, in that it flows freely and drifts and separates to fill the container it's in. Plasma occurs at super high temperatures, this strips apart the molecules. It can also occur at relatively cool temperatures, this plasma has very charged particles. They are electrically neutral, as they often contain equal numbers of protons and neutrons. But they are still affected by electric and magnetic fields, because they are so free flowing.

Define or explain the following terms. a) Equilibrium constant expression - b) Equilibrium constant - c) Absorbance - d) Beer's

tankabanditka [31]

Explanation:

(a) Equilibrium constant expression is ratio of concentrations of products over reactants each raised to their power of stoichiometric coefficients.

For example consider an equilibrium which is:

$aA+bB\rightleftharpoons cC+dD$

The expression is:

$K_c=\frac {[C]^c[D]^d}{[A]^a[B]^b}$

(b) Equilibrium constant of the chemical reaction is value of the reaction quotient of the reaction at the stage of chemical equilibrium which is a state that is approached by the dynamic chemical system at which the composition of the reactant and the product has no measurable tendency towards the change.

(c) Absorbance is the measure of capacity of the substance to absorb the light of a specific wavelength. Absorbance is equal to the logarithm of reciprocal of transmittance.

(d) The Beer's law relates attenuation of the light to properties of material through which light is travelling.

The expression for the law is:

A = ε × l× c

Where,

A is the absorbance

ε is molar absorptivity coefficient

l is the path length

c is the concentration.
