The law of conservation of energy states that energy can neither be created nor destroyed.
It can only be converted from one form of energy to another.
I hope this helps! ❤️

Answer:


Explanation:
In this reactor, oleic and linoleic acid react with hydrogen to form stearic acid. This reactions can be represented by:
Oleic: 
Linoleic: 
Having this reactions in mind, the first thing is to determine the moles of hydrogen required:
<u>Base of caculation: 1 mol of sunflower oil</u>
For oleic acid: 

For linoleic acid: 



Applying the excess:

Nitrogen: 

<u>After the reactions</u>:

and the nitrogen is inert.
Purge stream:



Answer:
Scheme is attached
Explanation:
When 3‑bromopentane reacts with hydroxide, (Z)-pent-2-ene will produce through E 2 (Z)-pent-2-ene.
Mechanism
Hydroxide ion (OH⁻ ) is a strong nucleophile so it abstract the proton from carbon next to the carbon attached with bromine.
The the carbon next to carbon of bromine gets -ve charge, mean while it shares its electrons with the carbon having bromine and make a double bond.
As bromine is a good leaving group so it easily gets detached from carbon, so that carbon comes to its normal state.
As a result (Z)-pent-2-ene will produce. we call it Z because mostly trans products will form.
Answer:
The correct option is: 2 shared pairs, 2 lone pairs
Explanation:
Water is an inorganic molecule that is composed of one central oxygen atom and two hydrogen atoms bonded by covalent bonds. The molecular formula of water is H₂O and the bond angle is 109.47°.
The <em>oxygen is sp³ hybridized</em> and there are<em> two bond (or shared) pairs and two lone pairs </em>of electrons in a water molecule. The<em> structure of H₂O is bent </em>due to the <u>repulsive forces between the lone pairs of electrons</u>.
<em>Due to these repulsive forces, the H-O-H bond angle decreases from 109.47°, which is the ideal bond angle to 104.45°.</em>
