Answer:
C. Solution B is less acidic than solution A.
The root words in this item are hydro- are lysis-. Hydro pertains to water and lysis is the disintegration of a cell or a compound. The word hydrolysis is the disintegration or the breaking of the compound because or due to its reaction with water. This usually brings about changes in pH of a solution.
Reactants are carbon dioxide and water, the products are glucose and oxygen. Don't know for sure what the yield is represented with, so, I can't help you with that.
Answer:
Molality = 7.5 mol/kg
Explanation:
Given data:
Mass of NH₄Cl = 6.30 g
Mass of water = 15.7 g (15.7/1000 =0.016 kg)
Molality = ?
Solution:
Formula of molality:
Molality = Moles of solute / mass of solvent in gram
Now we will first calculate the number of moles of solute( NH₄Cl )
Number of moles = mass/ molar mass
Molar mass of NH₄Cl = 53.491 g/mol
Number of moles = 6.30 g/ 53.491 g/mol
Number of moles = 0.12 mol
Now we will calculate the molality.
Molality = Moles of solute / mass of solvent in gram
Molality = 0.12 mol / 0.016 kg
Molality = 7.5 m
or (m=mol/kg)
Molality = 7.5 mol/kg
