Answer:
The coffee is the solvent. The sugar is the solute. The sweetened coffee is the solution.
Explanation:
False. Due to:
Entropy increases with molecular size (mass of compound)
HBr has greater molecular size (molar mass) than HCl
The value of standard entropy of HCl(g) is 187 joules/ kelvin
The value of standard entropy of HBr(g) is 199 joules / kelvin
Evaporation is one change.
Answer:
20%
Explanation:
mass by mass percentage of a solution =(mass of solute)/(mass of solution)
mass of solute=550g
therefore 110×100/550=20%
