Answer: Double displacement reaction
Explanation:
Double displacement reaction is defined as the reaction where exchange of ions takes place.
The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

<u>Answer:</u> The mass of glucose in final solution is 0.420 grams
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
.........(1)
Initial mass of glucose = 10.5 g
Molar mass of glucose = 180.16 g/mol
Volume of solution = 100 mL
Putting values in equation 1, we get:
To calculate the molarity of the diluted solution, we use the equation:
where,
are the molarity and volume of the concentrated glucose solution
are the molarity and volume of diluted glucose solution
We are given:
Putting values in above equation, we get:
Now, calculating the mass of final glucose solution by using equation 1:
Final molarity of glucose solution = 0.0233 M
Molar mass of glucose = 180.16 g/mol
Volume of solution = 100 mL
Putting values in equation 1, we get:
Hence, the mass of glucose in final solution is 0.420 grams
