Answer:
Ethane can be converted into 1- butanol in 4 different steps and reactions.
Explanation:
Step 1 : Ethane follows Markovnikov's rule and reacts with a protic acid called Hydrogen chloride to form Chloroethane.
Step 2: Chloroethane undergoes Wurtz reaction where it reacts with sodium metal in the presence of dry ether to form an higher alkane called butane.
Step 3: Butane undergoes chlorination where it reacts with an halogen called chlorine to form 1-chlorobutane.
Step 4: 1-chlorobutane reacts strong aqueous Potassium hydroxide (KOH) to form 1-butanol.
Attached to this answer is the handwritten conversion of Ethane to 1-butanol showing all the reagents and molecules synthesized along the way.
Answer:- NaClO(sodium hypochlorite) and 
(calcium hypochlorite) are the salts that are oxidizing agents in chlorine bleaches.
Explanations:- NaOCl reacts with water to form hypochlorous acid(HOCl) that works as a bleach as it could remove the color of the objects.
Hypochlorite ion can also produce chlorine ion and oxygen which also works as a bleach.
Answer:
Heat
Explanation:
Energy exchange occurs when two systems exchange energy between them, or a system exchange energy with its surroundings. This phenomenon can happen in two ways: heat or work.
The heat is the exchange of energy caused by the difference in temperature. So, when the systems lose heat, its temperature decreases, and when it gains heat, its temperature increases.
The work is the energy exchange caused by the difference in volume and pressure. When a gas expands, its volumes increase, and it does work to its surroundings. When it compresses, its volumes decrease and it suffers work from its surroundings.
So, when the wax melt, the temperature of it must have increased, and it has gained heat. The energy exchange as heat.
