How much of the stock solution of 2.0 M of Blue 1 dye would be needed to
create 10 mL of a 0.5 M solution of Blue 1 dye?

Answers

Answer:

2.5 mL

Explanation:

The following data were obtained from the question:

Molarity of stock solution (M₁) = 2 M

Molarity of diluted solution (M₂) = 0.5 M

Volume of diluted solution (V₂) = 10 mL

Volume of stock solution needed (V₁) =?

Thus, we can obtain the volume of the stock solution needed by using the dilution formula as illustrated below:

M₁V₁ = M₂V₂

2 × V₁ = 0.5 × 10

2 × V₁ = 5

Divide both side by 2

V₁ = 5/2

V₁ = 2.5 mL

Thus, 2.5 mL of the stock solution is needed.

During soldering, a mixture of metals ('solder') is heated until it melts. The molten metal falls into the gaps between two pieces of metal and freezes, joining the pieces of metal together. A 'soft solder' melts between 183 °C and 212 °C. A 'hard solder' melts between 620 °C and 680 °C. Explain the difference in melting ranges.

Answers

Answer:

[tex]31^oC[/tex]

Explanation:

Range = Highest value - Lowest value

A 'soft solder' melts between 183 °C and 212 °C.

Melting range of a 'soft solder' = [tex]212-183=29^oC[/tex]

A 'hard solder' melts between 620 °C and 680 °C.

Melting range of a 'hard solder' = [tex]680-620=60^oC[/tex]

So,

Difference in melting ranges = Melting range of a 'hard solder'  - Melting range of a 'soft solder' = [tex]60^oC-29^oC=31^oC[/tex]

Which of the following would form a precipitate in a reaction?
LiCl
ZnSO4
NaOH
CaSO4

Answers

Answer:

NaOH

Explanation:

Precipitation reaction can be used in wastewater treatment. When a contaminant forms an insoluble solid, then we can use this reaction to precipitate out the contaminated ions. In wastewater, a frequent presence of heavy metals can be found such as compounds of sulphide and hydroxide. So, we can add a source of hydroxide that is soluble (NaOH Or Na2S) that will result in a precipitation reaction.

What is reactivity series?

A reactivity series is an evidence based, calculated, and architecturally analytical advancement of a series of metals arranged from highest to lowest by their "reactivity."

The reactivity series is a group of metals arranged in decreasing order of reactivity.

It is used to calculate the products of single displacement responses in which one metal A replaces a further metal B in a solution if A is higher in the series.

The metal reactivity sequence is an array of metals arranged in descending order of their chemical reactivity. It aids in predicting whether one metal can displace another in a displacement reaction.

Here in the given options, potassium is the most reactive as it is present in the topmost position of the reactivity series.

Thus, the correct option is A.

How do electrons in the same atom differ?

Answers

Electrons in the same atom differ because they can have different quantum numbers

Further explanation

Atoms consist of sub-particles: electrons, protons, and neutrons

The proton is positively charged (+1), the electron is negatively charged (-1). and neutrons not charged (neutral)

The electron configuration shows the energy level in the atom

The further away from the core, the higher the energy level

In the electron configuration we follow 3 rules:

1. Aufbau: Electrons occupy orbitals of the lowest energy 2 Hund: electrons fill orbitals with the same energy level 3. Pauli: no electrons have the same 4 quantum numbers

Each orbital consists of 4 quantum numbers

n: the principal l: the angular momentum / azimuthal ml: the magnetic ms: the electron-spin

From Pauli's rule, an electron can have 3 same but different quantum numbers in ms (quantum spin)

For example in the 1s orbital, then the quantum value of the 2 electrons that occupy the orbital:

first electron: n = 1, l = 0, ml = 0, ms = +1/2 second electron: n = 1, l = 0, ml = 0, ms = -1/2

Therefore, in one orbital it is not allowed to fill more than 2 electrons because the quantum numbers will be the same

Hunter is in lab. He clears a spot on his lab bench to start working. He also puts his lab coat and goggles on. He then identifies where all of the safety equipment is. He notices his station is next to the fume hood, which ventilates the chemicals stored there. The noise of the fume hood was bothersome, so Hunter turned it off. Which could be an error in his set-up? He should not turn off the fume hood. He should wait to put on his coat until after the directions are given. He should wait to put on his goggles until after the directions are given. He should not sit next to the fume hood.

Answers

Answer:

He should not turn off the fume hood.

Explanation:

According to this question, Hunter is in a laboratory where he is about to commence work. He starts by adhering to some laboratory safety rules including putting on his lab coat and goggles. However, he was bothered by the noise of the fume hood, which was close to his station. He then decided to switch/turn it off.

The "TURNING OFF OF THE FUME HOOD" is Hunter's error in this experimental set-up. This is because the fume hood is a laboratory safety device that helps prevent the inhalation of harmful gases by laboratory workers. The fume hood is a ventilated compartment which ventilates i.e. passes out, the chemicals stored there.

Every experiment involving chemicals should be performed in the fume hood in order to curb the escape of fumes from this reactions. Hence, TURNING THE FUME HOOD OFF means that one of the safety laboratory protocols has been defaulted.

Answer:

He should not turn off the fume hood.
