When a volcano erupts it releases a large amount of dust, smog, rock, and other materials. Basically, these bits and pieces float to form a metaphorical dust cloud. These clouds can often block out the sun like an ordinary cloud; however, because the cloud is dark, even less sun will be able to get through. So because the sun can't reach the ground, the temperature might decrease.
Answer: the correct option is 1 (It ensures that the ester is uncharged and therefore insoluble in water so that the product can be filtered.)
Explanation:
Esters are formed through a process known as esterification. This involves the heating of a carboxylic acid with an alcohol while the water formed is continuously removed. In order for the reaction to occur at a maximum rate, an acidic catalyst is used. The most common acid catalysts includes:
- hydrochloric acid and
-sulfuric acid.
These catalyst needs to be neutralized in order to isolate the product. This is so because the solution begins to precipitate when the reaction mixture is neutralized.
Thus it is important neutralize the moisture in order to filter out the ester from the mixture, which otherwise will be in a dissolved state and will not be recoverable.
Answer:
Compost is a mixture of organic residues (manure, animal carcasses, straw, etc.) that have been piled, mixed and moistened to undergo thermophilic (high heat 113 to 160 degrees Fahrenheit) decomposition (SSSA, 1997).
Explanation:
Cytosine is a building block of DNA,
(brainliest would be appreciated)
is the orbital hybridization of a central atom that has one lone pair and bonds to three other atoms.
<h3>What is
orbital hybridization?</h3>
In the context of valence bond theory, orbital hybridization (or hybridisation) refers to the idea of combining atomic orbitals to create new hybrid orbitals (with energies, forms, etc., distinct from the component atomic orbitals) suited for the pairing of electrons to form chemical bonds.
For instance, the valence-shell s orbital joins with three valence-shell p orbitals to generate four equivalent sp3 mixes that are arranged in a tetrahedral configuration around the carbon atom to connect to four distinct atoms.
Hybrid orbitals are symmetrically arranged in space and are helpful in the explanation of molecular geometry and atomic bonding characteristics. Usually, atomic orbitals with similar energies are combined to form hybrid orbitals.
