Answer: The best way to determine which is which should be to figure out which cube is heavier.

Explanation: Copper is more dense than Iron so the cube that is heavier (or more massive) should be Copper, and the lighter cube, Iron.

You can determine which is which by weighting them

Copper usually weighs heavier than iron, so if you weigh them both on the scale, the heavier one would be the copper cube

Hope this helped!

Consider the equation ∆G = –nFE, where F = 9.648533289 x 104 C/mol. Given that n is the mole of e– transferred and the following
myrzilka [38]

Answer:

See explanation below.

Explanation:

In the equation  ∆G = –nFE,  E is the electromotive force ( cell potential ) in Volts.

Now in turn a Volt is defined as the potential difference that will impart one joule of energy per coulomb of charge that moves through two points.

V = J/C where J is Joules and C is coulombs of charge

Therefore in terms of units the equation will give us units of Joules:

[ mol] x [C/mol] x [J/C] = [J]

Find the volume of 0.130M sulfuric acid necessary to react completely with 65.9g sodium hydroxide
xxTIMURxx [149]

The volume of the 0.130 M sulfuric acid, H₂SO₄ required to react completely with 65.9 g sodium hydroxide, NaOH is 6.34 L

  • We'll begin by calculating the number of mole of in 65.9 g sodium hydroxide, NaOH. This can be obtained as follow:

Mass of NaOH = 65.9 g

Molar mass of NaOH = 23 + 16 + 1 = 40 g/mol

<h3>Mole of NaOH =?</h3>

Mole = mass / molar mass

Mole of NaOH = 65.9 / 40

<h3>Mole of NaOH = 1.6475 mole</h3>

  • Next, we shall determine the number of mole of H₂SO₄ needed to react with 1.6475 mole of NaOH. This can be obtained as follow:

2NaOH + H₂SO₄ —> Na₂SO₄ + 2H₂O

From the balanced equation above,

2 moles of NaOH reacted with 1 mole of H₂SO₄.

Therefore,

1.6475 mole of NaOH will react with = \frac{1.6475}{2} \\\\ = 0.82375 mole of H₂SO₄.

  • Finally, we shall determine the volume of 0.130 M sulfuric acid, H₂SO₄ required for the reaction.

Molarity of H₂SO₄ = 0.130 M

Mole of H₂SO₄ = 0.82375 mole

<h3>Volume of H₂SO₄ =? </h3>

Volume = mole / Molarity

Volume of H₂SO₄ = 0.82375 / 0.130

<h3>Volume of H₂SO₄ = 6.34 L </h3>

Therefore, the volume of the 0.130 M sulfuric acid, H₂SO₄ required for the reaction is 6.34 L
