D-Fructose is the sweetest monosaccharide. How does the Fischer projection of D-fructose differ from that of D-glucose?
nataly862011 [7]

Answer:

The projection of the Fisher projection of D-Fructose and D-glucose is that  The carbonyl carbon in D-glucose is carbon 1 (aldehyde), whereas in D-fructose, the carbonyl group is on carbon 2 (ketone).

Explanation:

An aldehyde is a compound containing a functional group with the structure −CHO, consisting of a carbonyl center and

A ketone is a functional group with the structure RC(=O)R', where R and R' can be a variety of carbon-containing substituents.

It is easier to determine the electron configurations for the p-block elements in periods 1, 2, and 3 than to determine the elec
andreyandreev [35.5K]

Answer:

See Explanation

Explanation:

Because you have to get through the d-block electron configurations for the rest of the p-block elements which is a hassle to do. You need to know how to account for electron stability, from which subshell to remove electrons, etc. because it is all weird for d-block.

Given the unbalanced equation: N2(g) + H2(g) → NH3(g)
mario62 [17]

Answer:

                   Option-4 (3:2) is the correct answer.

Explanation:

Following steps are taken to balance the given unbalanced chemical equation.

Step 1: Write the unbalanced chemical equation,

                         N₂ +  H₂ →  NH₃

Step 2: Balance Nitrogen Atoms;

There are 2 nitrogen atoms on left hand side and 1 nitrogen atoms on right hand site therefore, to balance them multiply NH₃ on right hand side by 2 i.e.

                         N₂ +  H₂ →  2 NH₃

Step 3: Balance Hydrogen Atoms;

Now, there are 2 hydrogen atoms on left hand side and 6 hydrogen atom on right hand site therefore, to balance them multiply H₂ on left hand side by 3 i.e.

                         N₂ +  3 H₂ →  2 NH₃

Now, the equation is balanced.

Step 4: Finding out mole ratios:

From balanced chemical equation it can be concluded that 3 moles of H₂ are involved in producing 2 moles of NH₃ hence, the mole ratio of consumption of H₂ to production of NH₃ is 3:2.
