Answer:

NaNH2, NH3

Explanation:

Choose the most appropriate reagent(s) for the conversion of propyne and 2-methyl-1-tosyloxy propane to 5-methyl-2-hexyne. NaNH2, NH3 NaOH, H2O KOCH2CH3, HOCH2CH3 H2SO4 NH3

answer is  NaNH2, NH3

NaNH2, NH3 is strong to to convert propyne into a nucleophilic salt which in turn displaced tosylate in  2-methyl-1-tosyloxy propane to yield  5-methyl-2-hexyne.

Propyne and 5-methyl-2-hexyne. are still of the same homologous series,, so no triple bond is broken during the reaction

The essence of a reagent is to bring the reaction to its end point

mixer [17]

Answer:

A)

Cl + O3 --> ClO + O2

2ClO --> ClOOCl

ClOOCl --> 2 Cl + O2

B)

Cl2 + 4O3 -> 2 ClO + 5O2

Explanation:

Step 1: Chlorine atoms react with ozone (O3) to form chlorine monoxide and molecular oxygen

Cl + O3 --> ClO + O2

Step 2: Chlorine monoxide molecules combine to form ClOOCl gas

2ClO --> ClOOCl

Step 3: ClOOCl absorbs sunlight and breaks into chlorine atoms and molecular oxygen

ClOOCl --> 2 Cl + O2

B) Overall Balanced equation

Cl2 + 4O3 -> 2 ClO + 5O2

A 0.907 mole sample of ideal gas at 12c occupies a volume of 4.25L. What is the pressure of gas?
mel-nik [20]

Pressure of the ideal gas=505.7kPa

Given:

No of moles=0.907mole

Temperature of the gas=12^{\circ} \mathrm{C}

Volume of the gas=4.25L

To find:

Pressure of the gas

<u>Step by Step Explanation: </u>

Solution:

According to the ideal gas equation

P V=n R T and from this pressure is derived as

P=\frac{n R T}{V}

Where P=Pressure of the gas

V=Volume of the gas=4.25L

n=No of the moles=0.907mole

R=Gas constant=8.314J / m o l^{-1} K^{-1}

T=Temperature of the gas=12^{\circ} \mathrm{C} =273+12=285K

Substitute these known values in the above equation we get

P=\frac{0.907 \times 8.314 \times 285}{4.25}

P=\frac{2149.13}{4.25}

P=505.7kPa

Result:

Thus the pressure of the ideal gas is 505.7kPa

Weak acids are poor conductors of:
valentina_108 [34]

Answer: Weak acids are poor conductors of electricity.

Explanation:

Weak acids are defined as the acids which dissociate weakly or partially when dissolved in water (polar solvent).

For example, CH_3COOH \rightleftharpoons CH_3COO^{-} + H^{+}

Due to less dissociation there will be less number of ions present in a solution of weak acid. As a result, a weak acid will be poor conductor of electricity.

As electricity is the flow of ions.

Thus, we can conclude that weak acids are poor conductors of electricity.
