- <u><em>2)NH</em></u><em><u>₃</u></em>
Explanation:
The answer choices of this question are:
<h2 /><h2>Solution</h2>
The key to answer this question is to realize that <em>NH₃</em> is a gas at the given temperatures.
The solutilibty of all gases always decreases when the temperature increases. Thus, the solubility of NH₃ will decrease when the temperature rises from 10ºC to 50ºC.
The reason for this behavior of gases is that the temperature and the kinetic energy of the particles are directly proportional. Thus, as the temperature incrases the kinetic energy of the particles increases.
As the kinetic energy of the molecules of gas in the liquid solution increases, their speeds also increase, meaning that more molecules will escape from the solution to the gas phase, leaving the soluton with less dissolved gas molecules.
Answer:
C
Explanation:
Because i just had to do this on my assignment and got 100
Lithium Hydroxide (LiOH) is an Arrhenius base
Lewis Structures of Ammonium Ion (RED) and Chloride Ions (BLUE) are attached below.
Lewis structures are those structures which shows the environment of electrons in a molecule. These structures basically depicts the bonding electrons and non-bonding electrons also known as Lone pair electrons.
In attached structure it can be seen that the ammonium ion is made when nitrogen atom is forming four single bonds with four hydrogen atoms and the formal charge on nitrogen becomes +1. While, in case of chloride ion the chlorine atom has four lone pair of electrons and has a formal charge of -1.
