What determines the transition between different states of matter?

Scrat [10]

Answer:

Phase transition is when a substance changes from a solid, liquid, or gas state to a different state. Every element and substance can transition from one phase to another at a specific combination of temperature and pressure.

What is the frequency of a wave of intrared light which has a wavelength of 4.35 * 10 ^ - 5 meters?

weqwewe [10]

Answer

6.9 x 10¹²Hz

Explanation:

Given parameters:

Wavelength of the wave = 4.35 x 10⁻⁵m

Unknown:

Frequency of the wave = ?

Solution:

The speed of a wave is related to the wavelength and frequency using the expression below;

C = Fλ

C is the speed of light = 3 x 10⁸m/s

F is the frequency

λ is the wavelength

Insert the given parameters and solve;

3 x 10⁸ = F x 4.35 x 10⁻⁵

F = $\frac{3 x 10^{8} }{4.35 x 10^{-5} }$ = 6.9 x 10¹²Hz

Write the equilibrium-constant expression for the reactionA(s)+3B(l)↽−−⇀2C(aq)+D(aq)A(s)+3B(l)↽−−⇀2C(aq)+D(aq)in terms of [A], [

Ilia_Sergeevich [38]

Answer:

$K_{c} = [\text{C}]^{2}[\text{[D]}$

Explanation:

$\rm A(s)+3B(l) \, \rightleftharpoons \, 2C(aq)+D(aq)$

The general formula for an equilibrium constant expression is

$K_{c} = \dfrac{[\text{Products}]}{[\text{Reactants}]}$

Solids and liquids are not included in the equilibrium constant expression.

Thus, for this reaction,

$K_{c} = [\textbf{C}]^{\mathbf{2}}\textbf{[D]}$
