Answer:
C. Sold solution
Explanation:
Using method of elimination;
A. Pure substance.
Bronze is not a Pure substance because the proportions of copper and tin are not the same in all bronze. This option is wrong.
B. Colloidal Suspension
This option is wrong. Colloidal suspension involves one substance dispersed in another.
C. Sold solution
The bronze bell is an alloy. This definition suitable represents it. It is a solid solution containing copper and tin. This is the correct option.
D. Heterogeneous Mixture
Bronze is a mixture, however it is homogeneous and not heterogeneous. his is because one can not distinguish the copper from the tin in the mixture.
Answer:
The conversion achieved for the first CSTR impeller is 0.382
Discrepancy = 0.188
Explanation:
The impeller divides the CSTR into 2 equal reactors of volume 500gal
Using V = FaoX/ (-ra)
500gal = Fao×Xa/[(KCao^2( 1 -X1)^2]
500gal = CaoVoX1/ KCao^2(1-X1)
500gal= 500gal × X1'/(1 - X1)^2
(1 -X1)^2 = X1
X1^2 - 3X1 + 1 = 0
X1= 0.382
Conversion achieved in the first CSTR is 0.382
Actual measured CSTR = 57% =57/100=0.57
Discrepancy in the conversions= 0.57 -0.383 =0.188
