Some good mutations would be like if there is a moth that is normally brown because that are how the trees are, then the trees change colors because of lets say pollution, the same mutation could happen to the moth will happen to it.

What happens as a result of photoelectric effect

natka813 [3]

Electrons are emitted from the surface of a metal in photoelectric effect.

<h3>What is the photoelectric effect?</h3>

The photoelectric effect is the emission of electron from the surface of a metal when light is shone on the surface..

For electrons to be emitted, the light must have a certain frequency known as threshhold frequency.

Therefore, electrons are emitted from the surface of a metal in photoelectric effect.

Consider the reaction.

vovangra [49]

Answer: The value of Keq for the reaction expressed in scientific notation is $1.6\times 10^{-5}$

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios.

For the given chemical reaction:

$2NOCl(g)\rightarrow 2NO(g)+Cl_2(g)$

The expression for $K_{eq}$ is written as:

$K_{eq}=\frac{[NO]^2\times [Cl_2]}{[NOCl]^2}$

$K_{eq}=\frac{(1.2\times 10^{-3})^2\times (2.2\times 10^{-3})}{(1.4\times 10^{-2})^2}$

$K_{eq}=1.6\times 10^{-5}$

The value of Keq for the reaction expressed in scientific notation is $1.6\times 10^{-5}$
