Answer:
The light goes through
Explanation:
The light goes through the transparent glass without being reflected or absorbed, for example, a window is a transparent glass, you never see light being reflected off of a window
Hope this helps (:
Answer:
32.57g
Explanation:
mass = mole x molar mass
mass of LiBr = 0.375 x 86.85
mass = 32.57g

Explanation:
Hello there!
In this case, for this titration problem, we first need to set up the undergoing chemical equation between barium chloride and hydrochloric acid:
Which occurs in a 2:1 mole ratio of acid to base and thus, we can write the following:
Which can be written in molarities and volumes:
And we solve for the molarity of the acid:
Unfortunately, the molarity of the base was not given:
"The molarity of an aqueous solution of hydrochloric acid, , is determined by titration with a M barium hydroxide, , solution. If 31.2 mL of barium hydroxide are required to neutralize 15.4 mL of the acid, what is the molarity of the hydrochloric acid solution?"
Yet we can assume an arbitrary value, say 1.0 M in order to show you the solution so that you can modify it according to your given value:
So you just need to modify the (1.0 M) by the actually given molarity of the acid.
Regards!
