Answer:
The phrase "you must live 'til you die", by Joseph Anton, carries a very deep message behind these simple words. Thus, the phrase implies that people, in all circumstances, must live every second of their lives fully, exploiting each and every one of their experiences in daily life to the fullest. That is, people must have the ability to abstract from their problems and their routines, being able to enjoy each circumstance of life beyond them. Otherwise, people would spend our time losing the ability to enjoy and value our circumstances and experiences. Therefore, it is necessary to put into practice what this phrase says, in order to have a better quality of life.
Answer:
Explanation:
The equation for this chemical reaction is:
Ba + Cl2 -> BaCl2
So 1 moles of Ba react with 2 mole of Cl2 to form 1 mole of BaCl2.
Given 114g of Ba and 186g of Cl2 and molar mass of 137g for Ba and 71g for Cl2,
there are 114/137 = 0.83 mole of Ba and 186/71 = 2.62 mole of Cl2.
Ba is the limiting reactant as it will be used up.
Cl2 is the reactant in excess and there will be 2.62 - 0.83*2 = 0.96 mole or 0.96*71 = 68.16g left.
Moles of BaCl2 formed = moles of Ba = 0.83
As mass of 1 mole of BaCl2 is 208.23g, 0.83 mole or 0.83 * 208.23 = 172.83g of BaCl2 can be made.
