Report the precise concentration of the undiluted stock solution #1 of TZ in micromoles per liter. This is your most concentrated (undiluted) standard solution for which you measured the absorbance. Use 3 significant figures. Molarity (μmol/L) =31.5
Given: [TZ] = 0.5461 mol/L
Answer:
The concentration of TZ solution in μmol/L is 546 μmol/L
Explanation:
Molarity of the TZ solution = 0.5461 mol/L
This means that 0.5461 moles of TZ are present in 1 L of solution.
Moles of TZ = 0.5461 mol
So, the concentration of TZ solution in μmol/L is :
546.1 μmol/L ≈ 546 μmol/L
When a bunsen burner is properly adjusted, the flame look like outer violet and inner blue colour.
<h3>What is the clolur of flame?</h3>
When a burner is properly adjusted the flame should have an outer violet oxidizing flame and an inner blue reducing flame. The temperature of blue colour is 15000 degree Celsius whereas the cool region outside the blue has 3000C temperature.
So we can conclude that When a bunsen burner is properly adjusted, the flame look like outer violet and inner blue colour.

An atom is the what makes up elements. It is made up of positive particles (protons), negative particles (electrons), and neutrons (no charged particles).
Protons and neutrons are in the center of the atom while electrons hover around.
You cannot predict an atom. This is because it is not anything to guess about -if you know what I mean.
Happy to help!
Answer:
The answer is C is attached to four unique gatherings A, B C and D, Thus it frame two optical isomers as the perfect representations of one another.
Explanation:
A critical class of isomers in which mixes have the equivalent sub-atomic recipe and structure, yet the distinction emerges from the introduction of the gatherings in the 3D space. Optical isomers are called as enantiomers.
Enantiomers are optical isomers whose identical representations are non-superimpose. They turn the plane enraptured light inverse way.
Optical action is characterized as the capacity of a choral atom to pivot the plane energized light. The enantiomers that pivots the plane energized light a clockwise way is called extraordinary, while the one that turns the plane spellbound light an anticlockwise way is called rotatory. Basics ,
Centrality is the major behind the optical movement of a natural atom. Choral focus: A'C' particle in a particle turns into a choral focus when all the four valences of that molecule are fulfilled by synthetically unique gatherings.
Answer:
1.0190 x 10⁻⁵ mol
Explanation:
We know the titration required 10.19 mL of 0.001000 M KIO₃, from this information we can calculate the number of moles KIO₃ reacted and from there the number of moles of ascorbic acid since it is a monoprotic acid ( 1 equivalent of ascorbic acid to one equivalent KIO₃).
Molarity = mol/V
V KIO₃ = 10.19 mL = 10.19 mL x 1 L/1000 mL = 0.01019 L
⇒ mol KIO₃ = V x M = 0.01019 L x 0.0010 mol / L = 1.0190 x 10⁻⁵ mol KIO₃
# mol ascorbic acid = # mol KIO₃ = 1.0190 x 10⁻⁵ mol
