Answer:  Physical Chemist

Explanation:  Chemical Kinetics is that branch of chemistry which deals with the study of understanding the concepts behind the rate at which the reaction proceeds .

This branch only deals with the direction of the reaction and the way it proceeds, it does not deals with the law of thermodynamics.

Thus Physical Chemist is the chemist who studies the mechanism that drives the rate of energy transfer in chemical reactions.

8 gm of pure calcium is treated with 50 gram of pure Hcl to give cacl2 and h2 .which is limiting reactant?​
elena-14-01-66 [18.8K]

Ca as a limiting reactant

<h3>Further explanation</h3>

Given

8 g Calcium

50 g HCl

<h3>Required</h3>

Limiting reactant

Solution

Reaction

Ca + 2HCl → CaCl₂ + H₂

mol Ca (Ar = 40 g/mol) :

= mass : Ar

= 8 g : 40 g/mol

= 0.2

mol HCl (MW= 36.5 g/mol) :

= mass : MW

= 50 g : 36.5 g/mol

= 1.37

Mol : coefficient reactants :

Ca = 0.2/1 = 0.2

HCl = 1.37/2 = 0.685

Ca as a limiting reactant(smaller ratio)

35mL of acid with an unknown concentration is titrated to completion using 63mL of 3.0 MNaOH.
siniylev [52]

Answer:

5.4 M.

Explanation:

  • At complete neutralization: It is known that the no. of millimoles of acid equal that of the base.

<em>(MV)acid = (MV)NaOH</em>

M of acid = ??? M, V of acid = 35.0 mL.

M of NaOH = 3.0 M, V of NaOH = 63.0 mL.

∴ M of acid = (MV)NaOH / (V)acid = (3.0 M)(63.0 mL)/(35.0 mL) = 5.4 M.

A student did not read the direction to the experiment properly and mixed up where to place the NaOH solution and the vinegar. H
Mariana [72]

Answer:

At end point there will a transition from pink to colorless.

Explanation:

As the student put the vinegar in the titrator and NaOH in the beaker, it means that he has poured phenolphthalein in the NaOH solution.

The pH range of phenolphthalein is 8.3-10 (approx), it means it will show pink color in basic medium.

So on addition of phenolphthalein in NaOH the solution will become pink in color.

When we start pouring vinegar from titrator neutralization of NaOH will begin.

On complete neutralization , on addition of single drop of vinegar the solution will become acidic and there will be complete disappearance of pink color solution in the beaker.
