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:
Ice cubes, glass of tea, and butter
Explanation:
Like it said in the hint, the molecules will only speed up if they gain heat. This means in order for the object to heat up it will have to have a temperature that is less than the temperature in the room. Ice cubes, glass of tea, and butter are the three objects that have a temperature less than 72 degrees so when they are placed in the 72 degrees room they will heat gain heat (therefore making the molecules move faster)
The elements have the same number of electrons in the outer ring so they react with the same substances
Answer:
ten atoms of hydrogen are present in one mole of caffeine.
Explanation:
Molecular formula of caffiene is given which is C3H10N4O2. It clearly shows that ten atoms of hydrogen are present. One mole is amount equal to one molecular weight of a molecule which is derived from molecular formula. So as moecular formula has ten atoms of hydrogen, one mole of caffeine has 10 atoms of hydrogen.
Most ocean life is found in coastal habitats. Coastal habitats have more light than the deep ocean resulting in a higher concentration of organisms. Plant species are especially abundant in coastal habitats.
