Explanation:
The balanced reaction of heating solid lead (II) sulfide with the solid lead (II) sulfate to produce liquid lead and sulfur dioxide gas is shown below:
In the balance reaction above, all the phases are indicated. This reaction is used for the production of lead metal.
Answer:
Burning of fossil fuels releases carbon dioxide into the air which is a greenhouse gas therefore it warms up the earth. Driving a car and factories are good examples

Explanation:
most of the world is made of water because the oceans.
Answer:
The routes are in the attached figure bellow.
Explanation:
In order to have a nucleophilic substituition, we need a substract with a positive or partially positive carbon. Therefore, the two possible substracts chosen were alkyl halides. The chlorine is more electronegative than the carbon, therefore the electronic density will be deslocated towards the Cl atom an the C atom will be left partially positive.
The nucleophiles given have strong negative charges and will attack the partially positive carbon. The chlorine will then leave the molecule (leaving group) and a new bond between the carbon and the oxigen will be formed.
Both routes will involve a Sn2 mechanism, which means that the reactions will occur in one step.
