Explanation:

Ionic solids are defined as the solids in which atoms of opposite charge are held together by strong forces of attraction. As a result, in solid state these atoms are not present in free state.

Hence, they cannot move as ions from one place to another. On the other hand, metals are able to conduct electricity because of the presence of free electrons in it.

As we know that electricity is the flow of ions or electrons from one place to another. Therefore, metals are able to conduct electricity in their solid state.

Draw the structures of organic compounds a and b omit all by products thf
Brums [2.3K]
The reaction is shown below,

Step 1: Hydration of Alkene:
                                            In first step Ethene is hydrated to Ethanol through Hydroboration Reaction.

Step 2: Oxidation of Primary Alcohol:
                                                          In this step partial oxidation of ethanol is carried out using mild Oxidizing agent <span>Pyridinium chlorochromate (PCC) and Acetaldehyde is produced.

Step 3: Reduction of Acetaldehyde followed by Oxidation:
                                                                                           In this step, first acetaldehyde is reduced to secondary alcohol using grignard reagent. After that the sec. alcohol is oxidized to ketone by using oxidizing agent CrO</span>₃.

In the balanced equation , CS2 + 3O2 = CO2 + 2SO2 , how many mol of O2 would react with 34.5 mol of CO2?
Arada [10]

<u>Given:</u>

Moles of CS2 (it cannot be CO2 as mentioned in the question, since O2 reacts with CS2 and not CO2) = 34.5 mol

<u>To determine:</u>

Moles of O2 undergoing the reaction

<u>Explanation:</u>

The reaction is-

CS2 + 3O2 → CO2 + 2SO2

Based on the stoichiometry: 3 moles of O2 reacts with 1 mole of CS2

therefore the moles of O2 that would combine with 34.5 moles of CS2 are

= 3 moles O2 * 34.5 moles CS2/1 mole CS2 = 103.5 moles

Ans: Around 104 moles of O2 would react with 34.5 moles of CS2
