In an electrolytic cell, the electrode that acts as a source of electrons to the solution is called the <u>cathode</u>; the chemical change that occurs at this electrode is called <u>reduction</u>.

<h3>Define Electrolyte:-</h3>

An electrolyte is a material that separates into charged ions when it is in contact with water. Cations are positively charged ions. Anions are ions that are negatively charged. A substance that may conduct an electric current when melted or dissolved in water is known as an electrolyte.

<h3>Electrochemical cell </h3>

There are three main categories of electrochemical cells. the galvanic cell, the concentration cell, and the electrolytic cell. These cells all share the same four fundamental components. These are the elements

  • The electrolyte serves as the conduit for current flow between the anode and the cathode. In an aqueous solution, it normally is homogeneous, but in moist soil, the concentration or kind of dissolved compounds may vary locally.
  • The anode, which can conduct electricity and is in contact with the electrolyte, corrodes when it combines with the chemicals in the electrolyte.
  • A metal also contacts the electrolyte at the cathode. It is protected from corrosion rather than corroded.
  • Anode and cathode are connected by the conductor, which also completes the circuit.

How to convert moles 3.612 x 10^23 atoms Fe
Finger [1]

Answer:

0.6 moles of Fe

Explanation:

Given data:

Number of atoms of Fe = 3.612×10²³

Number of moles = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

From atoms to mole:

3.612×10²³ atoms of Fe × 1 mole /  6.022 × 10²³ atoms

0.6 moles of Fe

At 2000 ∘C the equilibrium constant for the reaction 2NO(g)⇌N2(g)+O2(g) is Kc=2.4×103. If the initial concentration of NO is 0.1
Rasek [7]

Answer:

[N_2]=0.0866M

Explanation:

Hello there!

In this case, in agreement to the chemical reaction, it is possible for us to figure out the equilibrium concentration of the N2 product, via an ICE table plugged in the equilibrium expression:

Kc=\frac{[N_2][O_2]}{[NO]^2}\\\\2.4x10^3=\frac{x*x}{(0.175-2x)^2}

In such a way, when solving for x via quadratic equation or just a solver, it is possible to obtain:

x_1=0.0866M\\\\x_2=0.0884M

In such a way, since the root 0.0884 M produce a negative concentration of NO (0.175-2*0.0884=-0.0018M), we infer that the correct root is 0.0866 M; therefore, the concentration of N2 at equilibrium is equal to x:

[N_2]=x=0.0866M

Best regards!

If 300.0 grams of FeCr2O7 react, how many grams of O2 will be consumed
kvv77 [185]
You are given 300 grams of FeCr2O7. You are required to get the mass of O2 in grams. The first thing to do is to find a reaction between FeCr2O7 and O2. The balanced chemical reaction is 2Fe + 6Cr + 21/2O2 -> Fe2(Cr2O7)3. The molar mass of Fe2(Cr2O7)3 is 759.65 grams per mole and 32 grams per mole for O2.  
<span>
300g Fe2(Cr2O7)3 (1 mol Fe2(Cr2O7)3/759.65 g Fe2(Cr2O7)3)(21/2 mol O2/1 mole Fe2(Cr2O7)3)(32 g O2/1 mole O2) = <u>132.7 g O2</u></span>
