For the reaction 4 FeCl2(aq) + 302(g) → 2Fe2O3(s) + 4Cl2(g), what volume of a
Darya [45]

Answer:

V=10.12mL

Explanation:

Hello there!

In this case, according to the given chemical reaction, it is possible to evidence the 4:3 mole ratio between oxygen and iron (II) chloride; thus, we can compute the moles of the latter that are consumed by the given molecules of the former:

n_{FeCl_2}=4.32x10^{21}molec O_2*\frac{1molO_2}{6.022x10^{23}molec O_2} *\frac{4molFeCl_2}{3molO_2} \\\\n_{FeCl_2}=0.0095molFeCl_2

Now, since we have a 0.945-M solution of this iron (II) chloride, the corresponding volume turns out to be:

V=\frac{n_{FeCl_2}}{M}\\\\V=\frac{0.00956mol}{0.945mol/L}\\\\V=0.01012L\\\\V=10.12mL

Best regards!

The process of ____ occurs when magma, lava, or a solute in a solution becomes a solid and the internal components will arrange
satela [25.4K]

Answer:

D. Crystallization

Explanation:

Let's clarify the irrelevant terms first.

  1. unification: This term has nothing to do with chemistry at all
  2. lithification: When the problem mentions magma and lava, you might think that this term is related to the process here. However, 'lithification' <em>do </em>have a precise meaning in geology. It refers to the process where sediments collapses into one single rock under pressure, which has nothing to do with the process mentioned here.

Now, for 2 terms that might confuse you: 'solidification' and 'crystallization' these also has precise scientific definition

Solidification is defined the process where substances in <em>liquid</em> phase changes its phase to <em>solid</em>. On first glance, this answer might seems correct, and yes, it is correct for this question. But not the <em>most</em> correct.

The keyword here is  

 'the internal components will arrange its self in an  organized pattern.'

Crystallization is a special case of Solidification where the atoms or molecules of liquid solidify by spontaneously arrange themselves in periodic, ordered, and organized pattern. It might or might not happen during solidification depending on cooling rate, viscosity of liquid, and other factors.

So, Crystallization is the most correct answer here.
