When optically active (R)-2-methylcyclohexanone is treated with either aqueous base or acid, racemization occurs. Explain.
IrinaK [193]

Answer:

See explanation

Explanation:

Racemization is said to occur when a 1:1 ratio of (+) and (-) enantiomers of a compound are produced in a reaction.

The reaction of optically active (R)-2-methylcyclohexanone with either aqueous base or acid leads to the formation of a planar enol species for reaction with acid and a planar enolate species for reaction with base.

Both reactions involves the formation of achiral species which reverts back to the chiral product with equal chances of the formation of both enantiomers of the product during the process. This leads to racemization of the product in both cases.

For a single H2 molecule, H2 → 2H, the dissociation energy is 4.52 eV. How much energy would have to be put in (in kJ) to dissoc
grandymaker [24]

Answer: 7.2418 x 10^-19 joules

Explanation:

1 eV equals 1.602 x 10^-19 joules

Then 4.52eV will be multiplied by the above value to give 7.2418 x 10^-19 joules which is the energy required to dissociate the hydrogen molecule

A. Write a balanced chemical equation for this reaction below.
I am Lyosha [343]

Answer:

Fe(s) + 3H2O2(aq) ................. FeO3(s) + 3H2O (l)​

Explanation:

Fe(s) + H2O2(aq) ----------------   FeO3(s) + H2O (l)​

To balance the equation put coefficient of 3 at back of H2O and H2O2

Fe(s) + 3H2O2(aq) ................. FeO3(s) + 3H2O (l)​

To check, the number of atoms of each element on the left must be equal to that of the right.

Element                       Left.                            Right

Fe.                               1                                    1

H.                            3×2=6                                  2×3=6

O.                           3×2 =6.                            3+3 = 6

This shows that the equation is balanced

I hope this was helpful, please mark as brainliest
