If a solution conducts electricity, it is positive evidence that solute dissolved in solvent is electrolyte.
When it has sunlight and water
Answer:
34.8 mL
Explanation:
First we <u>convert 5.48 g of CuNO₃ into moles</u>, using its<em> molar mass</em>:
- 5.48 g CuNO₃ ÷ 187.56 g/mol = 0.0292 mol
Now we can <u>calculate the volume of the solution</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- 0.840 M = 0.0292 mol / liters
Finally we <u>convert L into mL</u>:
- 0.0348 L * 1000 = 34.8 mL
Answer:
See below.
Explanation:
Sucrose - negative because this is not a reducing sugar.
Lactose, Maltose, Fructose and Glucose - positive as they are reducing sugars..
Reducing sugars have a free aldehyde or ketone group whereas non-reducing sugars do not.
