Grease is nonpolar. It is made up of lengthy hydrocarbon chains attached to glycerol (triacylglycerols). Because of this property, nonpolar solvents, such as tetrachloroethylene, can get grease out of clothes. This solvent acts by dissolving the grease, thereby removing it from clothes without leaving any residue.
Answer:
Due to electrostatic force
Answer:
<em>Ethnocentrism is a normal reaction in taken pride in the success of your ethnicity but destructive when taken too far as to want to destroy other perceived lesser ethnic group.</em>
<em></em>
Explanation:
Ethnocentrism is the belief in the superiority of one's culture over others. Ethnocentrism is associated with the pride of falling into a particular culture, and is a learned behavior passed down from parents and society to the young ones among them. Ethnocentrism can be considered a normal reaction, when one finds oneself as a member a group that seems to have excelled in a particular way of life. Example is the feeling of pride that comes with your country winning the FIFA world cup; and its only natural to demonstrate ethnocentric characteristics in this case. A destructive effect of ethnocentrism can be demonstrated through genocide; in which a particular ethnicity rises up to destroy violently another perceived lesser ethnic group. This wrong ethnocentric drive has been a reason for the loss of millions of life globally.
Answer : The pressure in torr and in atmospheres are, 745 torr and 0.980 atm respectively.
Explanation :
As we are given that the atmospheric pressure is, 745 mmHg.
Now we have to determine the pressure in torr and atm.
Conversions used:
1 atm = 760 mmHg
1 atm = 760 torr
1 mmHg = 1 torr
As, 760 mmHg = 1 atm
So, 745 mmHg =
and,
As, 1 mmHg = 1 torr
So, 745 mmHg = 745 torr
Therefore, the pressure in torr and in atmospheres are, 745 torr and 0.980 atm respectively.
