Explanation :

(a) 4NH_3(g)+5O_2(g)\rightarrow 4NO(g)+6H_2O(g)

This reaction is combustion reaction in which an oxygen react with a molecule to give its corresponding oxides ans water molecule.

(b) S_8(s)+8O_2(g)\rightarrow 8SO_2(g)

This reaction is a redox reaction or oxidation-reduction reaction in which sulfur get oxidized and oxygen get reduced.

(c) 2Al(s)+3Cl_2(g)\rightarrow 2AlCl_3(s)

This reaction is a combination reaction in which the two reactants molecule combine to form a large molecule or product.

(d) 2AlN\rightarrow 2Al(s)+N_2(g)

This reaction is a decomposition reaction in which a large molecule or reactant decomposes to give two or more molecule or products.

(e) BaCl_2(aq)+Na_2SO_4(aq)\rightarrow BaSO_4(s)+2NaCl(aq)

This reaction is a double displacement reaction in which the cation of two reactants molecule exchange their places to give two different products.

(f) 2Cs(s)+Br_2(l)\rightarrow 2CsBr(s)

This reaction is a combination reaction in which the two reactants combine to form a large molecule or product.

(g) KOH(aq)+HCl(aq)\rightarrow H_2O(l)+KCl(aq)

This reaction is a double displacement reaction in which the cation of two reactants molecule exchange their places to give two different products.

(h) 2C_2H_2(g)+5O_2(g)\rightarrow 4CO_2(g)+2H_2O(l)

This reaction is combustion reaction in which a hydrocarbon react with an oxygen to give carbon dioxide and water as a products.

Ethyl acetate can be prepared by an SN2 reaction. Draw the alkylbromide and nucleophile used in the reaction. Remember to includ
bulgar [2K]

Answer:

Few important points related to S_N2 reaction:

1. S_N2 is a one-step reaction that follows second order kinetics.

2. In S_N2 reaction, a transition state is formed in situ.

3. Strong nucleophiles like OH^- \ or\  CN^- are used in case of bi-molecular nucleophilic substitution reaction.

Ethyl acetate can be prepared by a second-order nucleophilic substitution reaction between acetic acid and ethyl bromide.  

The reaction between acetic acid and ethyl bromide is drawn below:

It is common for students to overshoot the endpoint, meaning they add too much NaOH(aq) from the buret, which causes the solutio
umka2103 [35]

Answer: the percentage of acetic acid will be low.

Explanation: The major aim during titration of acids and bases is to  determine the endpoint , that is exact point where the acid  in the beaker changes colour, (in this case, pink )with an additional  drop from the burette containing the base, since it is usually difficult to mark the equivalence point that tells us when  all the substrate in the beaker has been neutralized completely with the buretted substance.

Overshooting the end point is  an error which can occur when the person involved in the  the titration accidently goes beyond this  endpoint by adding too much of the substance(base) from the burette into the beaker missing the exact endpoint.

This implies that the person  has  added too much of the burreted liquid, ie the base than required  , making the acid in the beaker to continue to react resulting  to a lower concentration of the acid (acetic acid)  with excess base.(NaOH)

What’s the fastest way to balance chemical equations
Anon25 [30]

Hey there!

The best way to balance chemical equations is to first start by balancing polyatomic ions such as OH and SO₄.

Next, balance other elements, but save elements that are by themselves for last, such as H₂ or Fe. Once you balance everything else you can do the ones by themselves, it's much easier.

Hope this helps!
