Predict the products for the following equation.
coldgirl [10]

Answer: AgCl + Fe

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.

A general single displacement reaction can be represented as :

XY+Z\rightarrow XZ+Y

The blanced chemical reaction will be :

3Ag+FeCl_3\rightarrow 3AgCl+Fe

Which of the following aqueous solutions has the highest boiling point?A. 1.25 M Ca(NO3)2B. 1.25 M KNO3C. 1.25 M CH3OHD. 2.50 M
Drupady [299]

Answer:

Ca(NO3)2 has the highest boiling point ( option A)

Explanation:

Step 1: Data given

A. 1.25 M Ca(NO3)2

B. 1.25 M KNO3

C. 1.25 M CH3OH

D. 2.50 M C6H12O6

Step 2: Calculate highest boiling point

The boiling point depends on the van't Hoff factor

This shows the particles produced when the substance is dissolved. For non-electrolytes dissolved in water, the van' t Hoff factor is 1.

Ca(NO3)2 → Ca^2+ + 2NO3- → Van't Hoff factor = 3

KNO3 → K+ + NO3- → Van't Hoff factor = 2

CH3OH is a non-elektrolyte → Van't Hoff factor = 1

C6H12O6 is a non-elektrolyte → Van't Hoff factor = 1

Ca(NO3)2 has the highest boiling point
