Answer:
The correct answer is: X is nitrogen dioxide, and Y is a metal oxide
Explanation:
Combustion of compound of containing nitrogen and metal will give nitrogen dioxide and metal oxide as product. During combustion reaction a compound reacts with oxygen in order to yield oxides of elements present in the compound.
The general equation is given as:
Hence, the correct answer is :X is nitrogen dioxide, and Y is a metal oxide.
Answer:
b.
Explanation:
Hello there!
In this case, given the ionization reaction of HClO as weak acid:
We can write the equilibrium expression as shown below:
In such a way, via the definition of x as the reaction extent, we can write:
As long as Ka<<<<1 so that the x on the bottom can be neglected. Thus, we solve for x as shown below:
And finally the percent dissociation:
Which is choice b.
