A monosaccharide that consists of 5 carbon atoms, one of which is in a ketone group, is classified as a(n) _______
Elenna [48]

A monosaccharide that consists of 5 carbon atoms, one of which is in a ketone group, is classified as a(n) ketopentose.

Ketone family

The suffix "-one" is added after locating the carbonyl group and, if necessary, designating it with a location number. Ketones are given their common names by first identifying the alkyl groups linked to the carbonyl (in alphabetical order), followed by the prefix "ketone." Several Regular Ketones. The three most significant ketones in terms of scale are acetone, methyl ethyl ketone, and cyclohexanone. Though less frequently than in general organic chemistry, they are still widespread in biochemistry. The simplest ketone is dimethyl ketone, or CH3COCH3, often known as acetone.

To learn more about the ketone group refer here:

Explain how a Buffer acts to resist pH change in a system upon addition of an acid or a base
Leokris [45]

Answer:

Explanation has been given below.

Explanation:

  • A buffer consists of either of a weak acid along with it's conjugate base or a weak base along with it's conjugate acid.
  • Let's consider a buffer consists of a weak acid along with it's conjugate base
  • If we add an acid to this buffer then conjugate base gets protonated and converted to corresponding weak acid. So effect of addition of acid gets neutralized by forming weak acid rather than increase in concentration of proton in solution.
  • If we add a base to this buffer then weak acid gets converted to corresponding conjugate base. So effect of addition of base gets neutralized by forming conjugate base rather than in crease in concentration of hydroxyl ion in solution.

How many atoms are found in 4.75 moles of Fe?
aliya0001 [1]

Answer:

The answer to your question is below

Explanation:

a)

Number of atoms = ?

moles of Fe = 4.75

-Use proportions to solve this problem

                            1 mol of Fe --------------------- 6.023 x 10²³ atoms

                          4.75 moles  ---------------------  x

                            x = (4.75 x 6.023 x 10²³) / 1

                            x = 2.86 x 10²⁴ / 1

  Number of atoms = 2.86 x 10²⁴

b)

Number of moles = ?

moles of 1.058 moles of H₂O

I think this question is incorrect, maybe you wish to know the number of atoms or grams of H₂O.

c)

Number of atoms = ?

moles of Fe = 0.759

                       1 mol of Fe ------------------ 6.023 x 10²³ atoms

                       0.759 moles ---------------  x

                        x = (0.759 x 6.023 x 10²³) / 1

                        x = 4.57 x 10²³ / 1

Number of atoms of Fe = 4.57 x 10²³ atoms

d)

Number of molecules = ?

moles of H₂O = 3.5 moles

                          1 mol of H₂O ------------------ 6.023 x 10²³ molecules

                         3.5 moles       ------------------   x

                          x = (3.5 x 6.023 x 10²³) / 1

                          x = 2.11 x 10²⁴ molecules

Number of molecules = 2.11 x 10²⁴
