The balanced chemical reaction is written as:
Sb2S3 + 6HCl = 6SbCl<span>3 + 3H2S
We are given the amount of </span><span>antimony(III) sulfide to be used in the reaction. This is amount will be used for the calculations. We do as follows:
2.85 g Sb2S3 ( 1 mol / </span><span>339.715 g ) ( 6 mol SbCl3 / 1 mol Sb2S3 ) (</span> 228.13 g / mol ) = 11.48 g SbCl3
The correct answer is B. The magnifying lens is a converging lens. It focuses the incoming light to one single point. It can be proved when you use the magnifying glass to burn a piece of paper. You can observe that the light will concentrate at a single point.
Its D because
Li = 6
Be =9
C= 12
O=15
Answer:
