Answer:
The correct answer is C) B is a base. I just did it.
Explanation:
<h2>1.15 moles</h2>
Explanation:
The ideal gas law is written as 
where 
are the pressure, volume and temperature,
is the number of moles of gas; and 
is the ideal gas constant. It is the same for all gases.
Given,
Since,
So,the number of moles is 
The chemical reaction would be expressed as follows:
HBr + LiOH = LiBr + H2O
We are given the volumes and corresponding concentration to be used for the reaction. We use these values to solve for the concentration of the other reactant. We do as follows:
0.253 mol LiOH / L solution ( 0.01673 L ) ( 1 mol HBr / 1 mol LiOH ) = 0.00423 HBr needed
Concentration of HBr =0.00423mol / .010 L = <span>0.423 M HBr </span>
Answer:
Albert Einstein is perhaps most famous for introducing the world to the equation E=mc2. In essence, he discovered that energy and mass are interchangeable, setting the stage for nuclear power—and atomic weapons. His part in the drama of nuclear war may have ended there if not for a simple refrigerator.
