You are given two unknown acids, HX and H2Y, and two values for Ka, 1x10^-7 and 1x10^9. You know that X is a much more electrone
Elena L [17]

Answer:

.

Explanation

In HX , X is more electronegative than Y so HX will ionise more because of  ionic bond between H and X . On the other hand H₂Y will be less polar as compared to HX so it will ionise to a lesser extent . Hence Ka will be more for HX . Ka represents the degree of ionisation of acid . Higher the ionisation , higher is the value of Ka . H₂Y which is less polar will ionise less and hence it will have lesser value of Ka .

Hence H₂Y will have value of 10⁻⁷ and HX will have value of ka equal to 10⁹ .

In which species does nitrogen have an oxidation number of zero?
VARVARA [1.3K]
The most common species of nitrogen in which its oxidation state is zero is the diatomic nitrogen (N_{2}). This is because the oxidation number of pure elements (whether alone as an atom or combined with other atoms of the same element such as the diatomic nitrogen) is always zero. 

In addition to diatomic nitrogen, there are diazonium (R-N_{2}^{+}) compounds where nitrogen has an oxidation number of zero.

Which of the following is one way to prevent the corrosion of iron? 
Drupady [299]
B: Painting over a metal surface in order to prevent rust is known as rust proofing and it works by preventing oxygen and water from reaching the metal surface thus preventing a redox reaction which would result in rusting.
