The correct answer for the question that is being presented above is this one: "c. clearcutting." Clearcutting<span>, clearfelling, or </span>clearcut<span> logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Clearcutting in itself is not an effective way to manage forests and trees.</span>
The concept we are looking for here is electronegativity. This concept is a measure of how strong an atom or element can attract a pair, that is bonding, of electrons to itself.
Fluorine is the element or atom of the greatest electronegativity. Electronegativity would increase as we move left to right of the periodic table.
The image provided shows the full reaction and the products of the reaction.
By heating 3-sulfolene, the compound breaks down into SO₂ gas and butadiene. The diene then reacts with the fumarate which is a dienophiles and these two species then undergo a Diels-Alder reaction. The diene reacts with the alkene portion of the fumarate and forms a new 6-membered cyclohexene ring. Since we have trans-fumarate, that leads to two potential products. We form a stereoisomer with stereocenters (1S, 2S) and another with stereocenters (1R, 2R). These two isomers formed are enantiomers. Therefore, the overall product is a racemic mixture of the two enantiomers.
While each individual enantiomer is optically active, the overall product would be racemic and therefore, not optically active.
Answer:
.001g/cm^3 are in 1kg/m^3
Explanation:
divide the mass / volume value by 1000
2.-> At the equivalence point, the pH = 7.00 for strong acid- strong base titrations.
3.-> A strong acid- strong base titration is performed using a phenolphthalein indicator. Phenolphtalein is chosen because it changes color in a pH range between 8.3 – 10. It will appear pink in basic solutions and clear in acidic solutions.
