What is the voltage for the nonspontaneous reaction between silver (Ag) and copper (Cu) and their ions?
gayaneshka [121]
For an non spontaneous reaction between silver (Ag) and copper (Cu) and their ions, Cu is the oxidizing agent while Ag+ is the reducing agent,
The following reactions will take place;
Anode Cu = Cu+2 + 2e-   E= +0.34 volts
Cathode; Ag+ + e = Ag    E = +0.80 volts
The net reaction will be Cu + 2Ag+ = Cu+2 + 2Ag
Thus, the voltage will be
  = +0.80 - (+0.34)

2 C2H2 + 5 O2<br> 2 H2O + 4 CO2 <br> what reaction type
Alexxx [7]

Answer:

Combustion reaction

General Formulas and Concepts:

<u>Chemistry</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>

2C₂H₂ + 5O₂ → 2H₂O + 4CO₂

<u>Step 2: Identify</u>

Any organic molecule reacting with oxygen to produce water and carbon dioxide is a combustion reaction.

We also see from the RxN that is is a double replacement reaction.

Jenna is playing with her toy cars, which are both the same size. She pushes the red car with a strong push. She pushes the blue
Vikki [24]

Answer:

red car will travel a much farther distance and at a faster speed as opposed to the blue car

Explanation:

Based on the information provided within the question Jenna can expect to observe that the red car will travel a much farther distance and at a faster speed as opposed to the blue car which will travel a shorter distance and at a lower speed. This is mainly because Jenna is applying an increased amount of force on the red car thus creating more acceleration and ultimately increasing the distance.
