Ice usually forms on the top part of lakes not the bottom , the reason for this occurence is?

Bingel [31]

Answer:

Ice is less dense than water because of the way it forms a hexagonal crystalline structure. Each water molecule consists of two hydrogen atoms bonded to the bottom of an oxygen atom. ... In the winter, temperatures in a lake get close enough to freezing that the colder water is less dense and floats to the top

In the activity, click on the Keq and ΔG∘ quantities to observe how they are related. Calculate ΔG∘using this relationship and t

NikAS [45]

<u>Answer:</u> The Gibbs free energy of the reaction is -114629.4 J

<u>Explanation:</u>

To calculate the Gibbs free energy of the reaction, we use the equation:

$\Delta G^o=-RT\ln K_{eq}$

where,

$\Delta G^o$ = Gibbs free energy of the reaction = ?

R = Gas constant = $8.314 J/K.mol$

T = temperature of the reaction = 298 K

$K_{eq}$ = equilibrium constant of the reaction = $1.24\times 10^{20}$

Putting values in above equation, we get:

$\Delta G^o=-(8.314J/mol.K\times 298K\times \ln (1.24\times 10^{20}))\\\\\Delta G^o=-114629.4J$

Hence, the Gibbs free energy of the reaction is -114629.4 J

What is the pH of a 0.1M acid solution? <br><br> A. 1<br> B. 0 <br> C. -1

Degger [83]

Hello!

We have the following data:

[H+] = 0.1 M → $1*10^{-1}$

Formula:

$pH = - log\:[H^+]$

$pH = - log\:[1*10^{-1}]$

$pH = 1 - log\:1$

$pH = 1 - 0$

$\boxed{\boxed{pH = 1}}\end{array}}\qquad\checkmark$

Answer:

A. 1
