<h2>The  half reaction that correctly describes the oxidation that is taking place in electrochemical cell containing Zn-Cu couple .</h2>

Explanation::

Electrochemical cell

It is the cell that converts the chemical energy in to electric energy .The reaction staking place in it are spontaneous that is occur by itself .

In it the oxidation and reduction both occur .

The one with high electrode potential looses electrons that is it shows : oxidation

Th one with lower electrode potential gains electrons that is  it shows :Reduction .

In this galvanic cell (Zn-Cu couple )

The oxidation occurs at anode that is :

Zn-2e---->Zn²⁺

The reduction occurs at cathode :

Cu²⁺  + 2e--->Cu

Which equation represents a double replacement reaction?
AveGali [126]

Answer:

C) LiOH + HCl → LiCl + H₂O

General Formulas and Concepts:

<u>Chemistry - Reactions</u>

  • Synthesis Reactions: A + B → AB
  • Decomposition Reactions: AB → A + B
  • Single-Replacement Reactions: A + BC → AB + C
  • Double-Replacement Reactions: AB + CD → AD + BC

Explanation:

<u>Step 1: Define</u>

RxN A:   2Na + 2H₂O → 2NaOH + H₂

RxN B:   CaCO₃ → CaO + CO₂

RxN C:   LiOH + HCl → LiCl + H₂O

RxN D:   CH₄ + 2O₂ → CO₂ + 2H₂O

<u>Step 2: Identify</u>

RxN A:   Single Replacement Reaction

RxN B:   Decomposition Reaction

RxN C:   Double Replacement Reaction

RxN D:   Combustion Reaction

URGENT!!!What volume of a 0.88 M solution can be made using 130. Grams of FeCI^2?
Likurg_2 [28]

Answer:

1.16L can be made

Explanation:

Molarity = Mol / Volume

Volume = Mol / Molarity

Let's determine the moles of salt, with that mass:

130 g FeCl₂ . 1mol / 126.75 g = 1.02 moles of FeCl₂

Volume = 1.02 mol / 0.88 mol/L → 1.16L
