Answer:
0.232M
Explanation:
H2SO4+2NaOH--> 2H2O+Na2SO4
(0.0684L)(.333M NaOH) = 0.0227 moles NaOH (1 mol H2SO4/2 mol NaOH)
= 0.0114 moles H2SO4
M = 0.0114 moles/ 0.0490L solution = 0.232M

This problem is requiring the balanced chemical equation that takes place when copper hydroxide and potassium sulfate are produced when reacting potassium hydroxide with copper sulfate.
<h3>Balancing chemical equations:</h3>
In chemistry, balancing chemical equations is based on the law of conservation of mass, which demands us to have equal number of atoms on both sides of the chemical equation. This can be accomplished by inserting coefficients in front of the chemical species.
For this particular case, we have potassium hydroxide with copper sulfate on the reactants side, however, copper can be copper (I) or copper (II) as it has 1+ and 2+ as its possible oxidation numbers. In addition, copper hydroxide and potassium sulfate as the products. Hence, we can assume this is all about copper (II) so we can write:

As we can see, potassium, hydrogen and oxygen have two atoms each on the products side, but just one on the reactants side; drawback we can overcome by putting a 2 in front of KOH so as to balance it:

Answer:
Reasonable Second step- 
Explanation:
The given single step chemical reaction is as follows.

Suppose a two-step mechanism is proposed for this reaction,
The reaction occured in two steps they are as follows.


Non of the above because protons and neutrons don’t mix with each one there
