Answer:

6 moles of Cl2

Explanation:

First, the equation has to be balanced, which makes it 4 FeCl3 + 3 O2 --> 2 Fe2O3 + 6 Cl2

Using this information, we can see that one mole of O2 will not be present in the reaction. Since four moles of FeCl3 are needed to react in the equation, which would produce six moles of Cl2, and only four moles of FeCl3 are present, six moles of Cl2 would be produced.

Which of the following buffer systems would you use if you wanted to prepare a solution having a pH of approximately 9.5?Which o
zalisa [80]

Answer:

b. 0,08M NH₄⁺ / 0,12M NH₃

Explanation:

<em>The buffers are:</em>

<em>a. 0,08M H₂PO₄⁻ / 0,12M HPO₄²⁻</em>

<em>b. 0,08M NH₄⁺ / 0,12M NH₃</em>

It is possible to find out the pH of a buffer using Henderson-Hasselbalch formula:

<em>pH = pka + log₁₀ [A⁻] / [HA] </em><em>(1)</em>

Where A⁻ is the conjugate base of the weak acid, HA.

a. For the system H₂PO₄⁻ / HPO₄²⁻ pka is <u><em>7,198</em></u>. Replacing in (1)

pH = 7,198 + log₁₀ [0,12] / [0,08]

<em>pH = 7,37</em>

That means this buffer system don't have a pH of approximately 9,5

b. For the system NH₄⁺ / NH₃ pka is <em><u>9,3</u></em>. Replacing in (1)

pH = 9,3 + log₁₀ [0,12] / [0,08]

<em>pH = 9,50</em>

That means this buffer system is the buffer you need to use.

I hope it helps!

Explain why the product at the negative electrode is not always a metal.
Elena-2011 [213]

Answer:

Whether you get the metal or hydrogen during electrolysis depends on the position of the metal in the reactivity series: the metal will be produced if it is less reactive than hydrogen. hydrogen will be produced if the metal is more reactive than hydrogen.

Do all solids have thermal energy? Why?
earnstyle [38]

Answer:

Yes because all solids have some thermal energy, its atoms do vibrate. However, this movement is very small and very rapid, and cannot be observed under ordinary conditions. When heat is added a solid can become a liquid.
