Remember that:
number of moles = mass/molar mass
First, we get the molar mass of the nitrogen gas molecule:
It is known the the nitrogen gas is composed of two nitrogen atoms, each with molar mass 14 gm (from the periodic table)
Therefore, molar mass of nitrogen gas = 14 x 2 = 28 gm
Second we calculate the mass of the precipitate:
we have number of moles = 0.03 moles (given)
and molar mass = 28 gm (calculated)
Using the equation mentioned before,
mass = number of moles x molar mass = 0.03 x 28 = 0.84 gm
Answer:
The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.
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.
