In order to find your answer you need to be <span>measuring entropy, so you will be using the following formula:
</span><span>delta S= S of (N2H4) + S of ( H2) - [2( S of NH3)]
</span>Hope this is very useful for you
Answer: asteroids and moon, planet, star, solar system, galaxy, universe.
Explanation:
Not Sure Let Me Review My Answer I Know I have Done This One Before Hmm!
Using equation:
pH+pOH=14
We are given pH=10.20 at 25°c.
So putting this value in the equation,
We have pOH=14-10.20
= 3.8
pOH=-log(OH)
-log(OH)=3.8
OH=0.00015M
So hydroxide concentration will be 0.00015 M.
Answer:
C. It is nonspontaneous and requires an electric current.
Explanation:
Electroplating refers to the process of coating a metal on the surface of another metal. Electroplating may be carried out to improve the properties of a metal or to preserve it from corrosion.
Electroplating involve the process of electrolysis. In electrolytic cells, electrical energy causes nonspontaneous reactions to occur in a process known as electrolysis. Electrolytes are decomposed during electrolysis by the passage of direct current to form ions.
The entire process of electrolysis is non spontaneous. It requires the input of electric electric current. This is achieved by connecting a battery to supply energy to drive the non spontaneous process.
