Williamson synthesis is the most common way for obtaining ethers, called after its developer Alexander Williamson. It is an organic reaction of forming ethers from an organohalide and an alkoxide. The reaction is carried out according to the SN2 mechanism.

On the attached picture it is shown required alkoxide ion, <span>alkyl(aryl)bromide and the ether that forms from the reactants. </span>

In an experiment, a student made a compund of sulfur and copper, and now she needs to find if the compound is copper (I) sulfide
finlep [7]

<u>Answer:</u> The formula for the given compound is Cu_2S

<u>Explanation:</u>

An ionic compound is defined as the compound which is formed when electron gets transferred from one atom to another atom. These are usually formed when a metal reacts with a non-metal.

The chemical formula of copper (I) sulfide is Cu_2S because this is formed by the combination of Cu^+ ions and S^{2-} ions

The chemical formula of copper (II) sulfide is CuS because this is formed by the combination of Cu^{2+} ions and S^{2-} ions

To calculate the percent composition of element in a compound, we use the equation:

\text{Percent composition of element}=\frac{\text{Mass of element}}{\text{Mass of compound}}\times 100       ...........(1)

  • <u>For copper (I) sulfide:</u>

Mass of copper = (2 × 63.546) = 127.092 g/mol

Mass of copper (I) sulfide = 159.16 g/mol

Putting values in equation 1, we get:

\text{Percent composition of copper in }Cu_2S=\frac{127.092g}{159.16g}=79.85\%

  • <u>For copper (II) sulfide:</u>

Mass of copper = 63.546 g/mol

Mass of copper (II) sulfide = 95.611 g/mol

Putting values in equation 1, we get:

\text{Percent composition of copper in CuS}=\frac{63.546g}{95.611g}=66.46\%

  • <u>Given compound:</u>

Mass of copper in given compound = 0.8383 grams

Mass of given compound = 1.0440 grams

Putting values in equation 1, we get:

\text{Percent composition of copper in given compound}=\frac{0.8383g}{1.044g}=80.29\%

The percent composition of copper is close to the composition in copper (I) sulfide.

Hence, the formula for the given compound is Cu_2S

85g=kg?<br> Unit conversion.
Paraphin [41]

Answer:

0.085 kg

Explanation:

1 g=0.001 kg  OR 1 kg=1000 g

 so \frac{85}{1000}=0.085 kg

Heat energy is useful to us in all the following ways except:
Lelechka [254]

Answer:

Heat energy is transferred to cooler objects to reduce the temperature of those objects.

Explanation:

The fourth option is not correct.

A correct way of writing it would be : " Heat energy is transferred from cooler objects to reduce the temperature of those objects.". When an object loses heat energy, its temperature reduces. Conversely, when an object receives heat energy, its temperature increases.
