Answer:

The correct option is B.

Which process occurs in a voltaic cell?

A voltaic cell is an electrochemical cell that uses a chemical reaction to produce electrical energy. The important parts of a voltaic cell: The anode is an electrode where oxidation occurs. The cathode is an electrode where reduction occurs.

What kind of energy is converted in a galvanic cell?

A galvanic cell is an electrochemical cell that converts the free energy of a chemical process into electrical energy. A photogalvanic cell is one that generates species photochemically which react resulting in an electrical current through an external circuit.

How many grams of CuSO4 5 H20 are needed to make 1 liter of a 2% (w/v) CuSO4. REPORT TO THE NEAREST 1/10 G.

Answers

Answer:

19.9 grams of $CuSO_4.5H_2O$ will be needed.

Explanation:

Required strength of the solution = 2% (w/v)

This means that 2 gram of solute in 100 ml of solution.

Mass of $CuSO_4.5H_2O$ = 2 g

Moles of $CuSO_4.5H_2O$ = $(2 g)/(249.68 g/mol)=0.008010 mol$

Volume of the solution = 100 mL = 0.1 L

Molarity of the solution:

$M=(0.008010 mol)/(0.1 L)=0.08010 mol/L$

0.08010 moles of $CuSO_4.5H_2O$ are present 1 l of the solution.

Then mass of 0.08010 moles of $CuSO_4.H_2O$ will be:

0.08010 mol × 249.68 g/mol = 19.9993 g≈ 19.9 g

19.9 grams of $CuSO_4.5H_2O$ will be needed.

Is clear water pumped from a deep aquifer a pure substance?

Answers

The substance which has definite composition with definite physical and chemical properties is said to be pure substance. These substances are not separated by the different physical techniques such as filtration, distillation, evaporation etc.

The clear water pumped from a deep aquifer is a pure substance because water is a pure compound which consist of constant single type of atoms or group of atoms and water has specific value of boiling and melting point. Water is also not separated into units or constituents by physical technique.

Hence, clear water pumped from a deep aquifer is a pure substance.

Answer:

Yes

Explanation:

As pure substances are substances that are formed directly by elements and water is directly formed by the union of two elements which is Oxygen and hydrogen, H2O is the formula and that is a pure substance as it is conformed mainly by only these two elements, so the question would be Yes, clear water pumped from a deep aquifer is a pure substance.
