Asalt is formed when nitric acid combines with sodium hydroxide. what ions are present in the salt that forms?

Explanation:

It is double displacement reaction in which exchange of ions take place.

When an acid and base combines to give salt and water, the double displacement reaction is called as neutralization. the  nitric acid is a strong acid which dissociates to give and ions an d sodium hydroxide is  a strong base which dissociates to give   and ions.

They result into formation of sodium nitrate which dissociates in water to give and ions.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
