<span>If you overshoot the endpoint of the acetic acid/NaOH titration, the expected effect on the calculated concentration of acetic acid will be higher because the volume measured for the titrant NaOH which is assumed to react with the acetic acid is more than what is needed to completely react with the given solution.</span>
Answer:
<h2>The atom having 5 proton (B) atom when a boron become cations , the numbers of protons is still 5 no mater how many electrons are lost . therefor , the three different atomic cations that all have 5 protons:
B<u>+</u><u>,</u><u>B2</u><u>+</u><u> </u><u>and</u><u> </u><u>B3</u><u>+</u></h2>

Answer:
1.67 mol S
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
53.7 g S
<u>Step 2: Define Conversions</u>
Molar Mass of S - 32.07 g/mol
<u>Step 3: Convert</u>
<u /> = 1.67466 mol S
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
1.67466 mol S ≈ 1.67 mol S
Answer : The rate law for the following mechanism is
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
As we are given the mechanism for the reaction :
Step 1 : (fast)
Step 2 : (slow)
Overall reaction :
The rate law expression for overall reaction should be in terms of A and B.
As we know that the slow step is the rate determining step. So,
The slow step reaction is,
The expression of rate law for this reaction will be,
............(1)
Now applying steady state approximation for , we get:
...........(2)
Now substituting equation 2 in 1, we get:
Hence, the rate law for the following mechanism is
