<u>Answer:</u> The value of for the net reaction is 13.94
<u>Explanation:</u>
The given chemical equations follows:
<u>Equation 1:</u>
<u>Equation 2:</u>
The net equation follows:
As, the net reaction is the result of the addition of first equation and the reverse of second equation. So, the equilibrium constant for the net reaction will be the multiplication of first equilibrium constant and the inverse of second equilibrium constant.
The value of equilibrium constant for net reaction is:
We are given:
Putting values in above equation, we get:
Hence, the value of for the net reaction is 13.94
Answer: Ag, Zn, Pd. (Ag is has the highest conductivity and Pd has the lowest conductivity).
Explanation:
The correct answer is not among the options given.
You must look up the electrical conductivity of these metals in a table of metal properties.
The values that you can find are:
- Ag: 62.1 × 10⁶ Siemmens / m
- Zn: 16.6 × 10⁶ Siemmens / m
- Pd: 9.5 × 10⁶ Siemmens / m
So in order of decreasing conductivity the list is Ag > Zn > Pd.
Answer:
Anion is negatively charged particle.
Calcium +2. Its cation
Oxygen -2
Explanation:
An anion is a charged particle with a negative charge. Anions has charge of -1
Oxygen require two electrons to complete its octet and hence its charge is -2
Calcium is a cation and has a positive charge of +2
That is a chemical change. Oxidization (rusting) is what happens. An example of this is the Statue of Liberty. It wasn't always the greenish we know!
Answer:
The ratio of atoms of potassium to atoms of oxygen is 2:1
Explanation:
As the equation given is :
<h3>
</h3>
The product formed is 2 moles of potassium oxide .
Amount of potassium atom in the potassium oxide is 2 atoms of potassium and amount of oxygen atom present here is 1 atom of oxygen .
But we have 2 moles of potassium oxide . So, the potassium and oxygen atoms will be multiplied by 2 .
Hence , we get 4 atoms of potassium and 2 atoms of oxygen .
Ratio of potassium to oxygen atoms is - 4:2
Therefore , 2:1
