Which of the following acids is the weakest? The acid is followed by its ka value. A) HC2H302, 1.8 * 10-5 B) HIO, 23 x 10-11 OC)
NemiM [27]

Answer:

the weakest acid is B) HIO

Explanation:

pKa = - log Ka

the higher the value of pKa, the lower the dissociation, therefore, an acid will be stronger the lower its pKa.

a) HC2H3O2; Ka = 1.8 E-5

⇒ pKa1 = - Log (1.8 E-5) = 4.745

b) HIO;  Ka = 23 E-11

⇒ pKa2 = - Log ( 23 E-11 ) = 9.638

c) HBrO;  Ka = 23 E-9

⇒ pKa3 = - Log ( 23 E-9 ) = 7.638

d) HClO;  Ka = 2.9 E-8

⇒ pKa4 = - Log ( 2.9 E-8 ) = 7.537

e) HCO2H; Ka = 63 E-5

⇒ pKa5 = - Log ( 63 E-5 ) = 3.200

from the values pKa, we places the acids from the weakest to the least weak:

1) pKa2; HIO (weakest)

2) pKa3

3) pKa4

4) pKa1

5) pKa5

Activities that shows the nature and goals of anthropology,Sociology and Political Science​
frez [133]

To answer the question effectively, we will talk about the key words in the question.

ANTHROPOLOGY, SOCIOLOGY AND POLITICAL SCIENCE.

ANTHROPOLOGY; This is the study of human kinds in all times and places,it also entails humanistic study which includes our prehistoric origins and contemporary human diversity as well as topics like social change,globalization,human origin and the world history.

The activities that shows the nature and goals of anthropology includes;

- Looking at ones own culture in a more objective way like an outsider.

- Discovering the things that make people more different from one another.

- Producing new theories and knowledge about human home and their behaviors.

- Discovering/finding out what all people have in common.

There are four fields of anthropology; Linguistic anthropology, Biological anthropology, Archeology and cultural anthropology.

SOCIOLOGY; This is the scientific study of human civilization.

It is systemic and studies of groups and societies that people build

and the effect these have on their behavior.

Sociology greatly focuses on various social connections,

structures, organizations, processes and institutions.

The activities that show the goals and nature of sociology includes;

- Broadening our familiarity on facts about sociology.

- Critically studying the nature of humanity.

- Exposing our minds to the diverse perspectives on attaining the truth.

- Obtaining possible theories about the society.

- Understanding and appreciating that all things in the society are interdependent with each other.

Sociology brings together inputs that are composed of frequent forms and manners,they include; view points, consolidated values, attitudes and the norms of social institutions.

The different branches of sociology are; social psychology,social organisation, applied sociology, population studies, sociological theory and research,human ecology,social change.

POLITICAL SCIENCE; This is a discipline in academics that deals with the study of political processes, institutions, governments and behaviors of people.

It studies the complex behaviors of the people in power, various political actors, such as the government administration, opposition ad the subjects which are the masses.

Which compound will conduct electricity when it is dissolved in water? CH4 CuSO4 C6H6 C6H12O6
mestny [16]
I would say CuSO4 or Copper Sulfate, as option 1 is Methane and would create a fire so heat, and the last one is Sugar which doesn't conduct electricity.  And C6H6 I believe is not soluble in water.<span />

The protein lysozyme unfolds at a transition temperature of 75.5°C, and the standard enthalpy of transition is 509 kJ mol-1. Cal
spin [16.1K]

Answer:

0.4774 KJ/K.mol

Explanation:

We are told that the transition at 25.0°C occurs in three steps. Steps i, ii and iii.

Thus;

the entropy of unfolding of lysozyme = ΔS_i + ΔS_ii + ΔS_iii

Now,

C_p,m(unfolded protein) = C_p,m(folded protein) + 6.28 kJ/K.mol

Now, for the first process, ΔS_i is given as;

ΔS_i = C_p,m × In(T2/T1)

We are given;

T1 = 25°C = 25 + 273.15K = 298.15 K

T2 = 75.5°C = 75.5 + 273.15 K=348.65 K

Thus;

ΔS_i = C_p,m × In(348.65/298.15)

Now, for the third process, ΔS_iii is given as;

ΔS_iii = (C_p,m + 6.28 kJ/K.mol) × In(T1/T2)

Thus;

ΔS_iii = (C_p,m + 6.28 kJ/K.mol) × In(298.15/348.65)

Now, we don't know C_pm. So, we have to find a way to eliminate it. We will do it by rewriting In(298.15/348.65) in such a way that when ΔS_iii is added to ΔS_i, C_p,m will cancel out. Thus;

In(298.15/348.65) can also be written as;

In(348.65/298.15)^(-1) or

- In(348.65/298.15)

Thus;

ΔS_iii = - [(C_p,m + 6.28 kJ/K.mol) × In(298.15/348.65)]

Now, let's add ΔS_iii to ΔS_i to get;

ΔS_i + ΔS_iii = [C_p,m × In(348.65/298.15)] + [(-C_p,m - 6.28 kJ/K.mol) × In(348.65/298.15)]

ΔS_i + ΔS_iii = [C_p,m × In(348.65/298.15)] - [C_p,m × In(348.65/298.15)] - [6.28In(348.65/298.15)]

First 2 terms will cancel out to give;

ΔS_i + ΔS_iii = -6.28In(348.65/298.15)

ΔS_i + ΔS_iii = -0.9826 KJ/K.mol

Now,for process ii;

ΔS_ii = standard enthalpy of transition/Transition Temperature

Thus;

ΔS_ii = (509 KJ/K.mol)/348.65

ΔS_ii = 1.46 KJ/K.mol

Thus;

the entropy of unfolding of lysozyme = ΔS_i + ΔS_ii + ΔS_iii = -0.9826 + 1.46 = 0.4774 KJ/K.mol
