Question 1: Complete and then stability the following acid-base reaction.

NaOH (aq) + HCl (aq) NaCl (aq) + H2O (l)

Question 2: Balance the following equation.

Oxygen + Ammonia Nitrogen gas + Water
3 O2 (g) + 4 NH3 (g) two N2 (g) + 6 H2O (l)

Question 3: Balance the following equation.

Methane + Oxygen Carbon (IV) oxide + Water
CH4 (g) + 2 O2 (g) CO2 (g) + 2 H2O (l)

Question 4: Using sodium chloride as an example, quickly explain how an ionic bond is formed.

Solution

When elements take phase in a reaction, they tend to gain or lose electrons in the bid to turn out to be stable. There are different types of bonds that are formed when the elements take part in a reaction. The main types of bonds include the covalent, ionic and dative bonds. An ionic bond is formed when the metals and non-metals take part in a chemical reaction. This type of bond involves a metal completely transferring its valence electrons to a non-metal (Helmenstine, 2017). The metals have valence electrons in their outermost energy level; therefore, when reacting with non-metals, they donate the delocalized electrons to the non-metals outermost energy shell. Sodium is an alkali metal; thus, it has one valence electron while chlorine has seven valence electrons since it is a halogen. The sodium atom loses one valence electron to obtain an octet state to the chlorine which also obtains an octet state. The elements are usually stable when they have either octet or duplet state in the case of helium (Bettelheim, Brown, Campbell, Farrell, & Torres, 2012).

Question 5: Using water and carbon dioxide as examples, briefly explain the difference between a polar covalent bond and a non-polar covalent bond.

Solution

A chemical reaction between non-metals constitutes a covalent bond. A water molecule is formed from the reaction between one oxygen atom and two hydrogen atoms while carbon dioxide from two oxygen atoms and one carbon atom. Both water and carbon dioxide have a covalent bond; however, the bonding in water is described as polar covalent. A polar covalent bond is formed from the unequal distribution of the shared electrons. One of the atoms in the molecules pulls electrons closer to itself strongly than the other atom. Therefore, since the electrons generally carry a negative charge, one end of the molecule will attain a slightly negative charge since the electrons are closer to it. On the other hand, the atom which has less strength in pulling the electron becomes partially positive. In the case of carbon dioxide, there is equal sharing of electrons between the atoms (Helmenstine, 2017)

Question 6: Le Chatelier’s Principle states that if a change of condition is applied to a system in equilibrium, the system will alter the equilibrium position in the direction which best reduces the impact of the change of condition. What will happen to this reaction under the following circumstances?

a) We add acetic acid to the mix? 
A forward reaction will be favoured since more acetic acid will react with ethanol to produce more ethyl acetate and water. However, after some time, the system will attain a new equilibrium position (Bettelheim et al., 2012).
b) We add ethyl acetate to the mix?
The backward reaction will be favored as more of the ethyl acetate will react with water to form more of ethanol and acetic acid.

First time when I placed an order with you, I just lacked time to do all the homework and it was a lot going on in my family. But today I’m doing it sometimes just for fun – I really enjoy communicating with your Customer Support members and just letting myself being a bit lazy

My GPA is 4.0 and I’ve always been doing everything myself, but there is a class which I was about to fail thus my GPA would decrease first time in so many years. I ordered few assignments to be completed with GrabMyEssay.com and you did a great job! Thanks to you I still remain one of the best students on campus.

I am not used to such services and I usually write all the papers by myself. But this time I got in a very difficult situation and had to order my paper on this website. To my surprise it appeared to be quite good. Thank you, it is really nice service. Think I'll get back to you soon!

I am on my maternity leave now, so I spend a lot of time at home taking care of my little son. I’ve decided to get one more higher education degree while I’m spending so much time at home and applied for distance learning in one online college. But caring a baby takes even more time then I excepted so I’m the way too busy to write the complicated masters level research works, but GrabMyEssay.com is so-so-so cool! Thank you for that you exist! I don’t know what I would do without you all!
