Write the equation for the production of one hexose sugar molecule from carbon dioxide
Naddik [55]

Answer;

6CO2 + 18ATP + 12 NADPH → C6H12O6 + 18ATP + 18Pi + 12NADP+

Explanation;

-The process of Calvin Cycle Synthesizes Hexoses from Carbon Dioxide and Water.

-The ATP and NADPH molecules produced by the light-dependent reactions of photosynthesis power sugar synthesis in the Calvin cycle. In the Calvin cycle, three molecules of CO2 are added to three molecules of ribulose bisphosphate (RuBP), a 5-carbon sugar already present in the stroma.

-This results to a total of eighteen carbons in the cycle.  As the three RuBP molecules accept a molecule of carbon dioxide, they immediately break down into six 3-carbon molecules of phosphoglyceric acid which is a hexose.

A chemist fills a reaction vessel withmercurous chloridesolid,mercury (I)aqueous solution, andchlorideaqueous solution at a temp
zloy xaker [14]

Answer:

Free energy change of the reaction is +98.83 kJ/mol.

Explanation:

The dissociation reaction of mercury(I) aqueous solution is as follows.

Hg_{2}Cl_{2}(s)\rightarrow Hg_{2}^{2+}(aq)+2Cl^{-}(aq)

The standard free energy of the reaction is as follows.

\Delta G_{rxn}^{o}=m\Delta G^{o}(products)-n\Delta G^{o}_{reactants}

=[(1\times \Delta G^{o}_{f(Hg_{2}^{2+})})+(2\times \Delta G^{o}_{f(Cl^{-})})-(1\times \Delta G^{o}_{f(Hg_{2}Cl_{2})})]

=[(1\times 153.5+2\times -131.25)-(1\times -210.78)]kJ=+101.78kJ

Gas\,constant"R"=8.314\times 10^{-3}kJK^{-1}mol^{-1}

Temperature=25^{o}c=25+273=298K

Free\,energy\,change\,of\,the\,reaction=\Delta G=\Delta G^{o}+RT\,lnQ

\Delta G=\Delta G^{o}+RT\,ln([Hg_{2}^{2+}][Cl^{-}]^{2})

=(101.78kJ)+8.314\times 10^{-3}kJK^{-1}mol^{-1}\times298K ln((0.926)(0.573)^{2})

=(101.78kJ)+(-2.95kJ)=+98.83kJ/mol

Therefore, Free energy change of the reaction is +98.83 kJ/mol.

Which of the answer choices best completes the analogy?
Zolol [24]

atomic fingerprint

Explanation:

The analogy is:

     individual : identification card              :: element : <u>atomic fingerprint</u>

An individual is represented and can easily be recognized by their respective identity cards. Most identification cards of people have their biodata which is composed of name, address, age, date of birth e.t.c. An identity card can solely be used to recognize and pick out a person.

Since the analogy seeks for a means to recognize elements, atomic fingerprints is good way;

  • Atomic fingerprint is the emission or absorption spectra of an atom.
  • It is a unique line of spectra that typifies an atom.
  • Every atom have their respective spectra different from those of others.
  • The atomic fingerprint can be used to identify an element.

Determine the number of moles of mg2+(aq) ions produced when 2.5 moles of zn 2+aq react completely in this cell
Montano1993 [528]
The question is incomplete. Complete question is attached below.

Solution:
The reaction involved in present electrochemical cell is:

Mg(s)     +       Zn2+(aq.)      ↔        Zn(s)      +      Mg2+ (aq.)

Thus, from above reaction it can be seen that 1 mole of Zn2+ produces 1 mole of Mg2+.

Thus, 2.5<span> moles of Mg2+(aq) ions would be produced when 2.5 moles of Zn2+(aq) will react.</span>
