Answer is: chemical formula of blue vitriol is CuSO₄.
In this molecule copper has oxidation number +2 and sulfate has oxidation number -2, copper(II) sulfate has neutral charge (+2 +(-2) = 0).
Copper sulfate is produced industrially in chemical reaction of copper metal and hot concentrated <span>sulfuric acid.</span>

2Pb(s) + O2(aq) + 4H+(aq) → 2H2O(l) + 2Pb2+(aq)
defon

Answer:

The answer to your question is 0.269 g of Pb

Explanation:

Data

Lead solution = 0.000013 M

Volume = 100 L

mass = 0.269 g

atomic mass Pb = 207.2 g

Chemical reaction

                        2Pb(s) + O₂(aq) + 4H⁺(aq) → 2H₂O(l) + 2Pb₂⁺(aq)

Process

1.- Calculate the mass of Pb in solution

Formula

Molarity = \frac{number of moles}{volume}

Solve for number of moles

Number of moles = Volume x Molarity

Substitution

Number of moles = 100 x 0.000013

Number of moles = 0.0013

2.- Calculate the mass of Pb formed.

                       207.2 g of Pb ----------------- 1 mol

                             x g             ----------------- 0.0013 moles

                        x = (0.0013 x 207.2) / 1

                        x = 0.269 g of Pb

Which of the following affects cell potential?
Slav-nsk [51]

Answer:

the standard cell potential value

Explanation:

For every cell, we can calculate its standard electrode potential from the table of standard electrode potentials listed in many textbooks.

However, from Nernst's equation;

Ecell= E°cell - 0.0592/n log Q

Hence the standard cell potential (E°cell) affects the value of the calculated cell potential Ecell from Nernst's equation as stated above.

Assuming the following materials will not mix,show how the materials would "Stack up" in a graduated cylinder.
mihalych1998 [28]

<u>Answer:</u>

Density is mass per unit volume.

Its formula is  

Density = Mass / Volume

Its units can be kg/L  or kg/(dm^3) or g/mL or g/(cm^3)

Density of various substances are given. The more denser substance goes to the bottom of the graduated cylinder.  

Air on the top then comes  Wood followed by  Corn oil followed by  Ice and then  Water followed by  Glycerin then  Rubber then  Corn syrup and at last  Steel at the bottom  which will more denser than all the substances mentioned above.

The staking up of the substances is in the order mentioned below in the tabular column
