There is no way to know which reaction requires which catalyst. However, if you apply copper to a reaction where it does act as a catalyst, the rate of reaction will be much faster as it lowers the activation energy for successful collisions.
The answer is C. The others are either a compound or an element
Answer:
The value is
Explanation:
From the question we are told that
The concentration of is
The concentration of is
The concentration of is
The concentration of is
Generally the log of the activity coefficient is mathematically represented as
Here z is the charge which for is +1
is the size which for is
is the ionic strength which is mathematically represented as
=>
So
=>
=>
=>
Generally the pH is mathematically represented as
=>
Answer:
The answer to your question is b. Mg is being oxidized and c. Mg is the
reducing agent.
Explanation:
Reduction is the gain of electrons
Oxidation is the loss of electrons
Reducing agent is the element that oxidizes itself and reduces another element.
Oxidizing agent is the element the reduces itself and oxidizes another element.
In this reaction:
Magnesium loses electrons so it is being oxidized and it is the reducing agent.
