Alex787 [66]

Answer:

A and B are unfavorable reactions.

Explanation:

In chemical thermodynamics, an endergonic reaction is also called a nonspontaneous reaction or an unfavorable reaction. it's a chemical reaction in which the change in free energy is positive, and energy is absorbed.

In chemical thermodynamics, an exergonic reaction is also called a spontaneous reaction or a favorable reaction. it's a chemical reaction in which the change in free energy is negative.

ΔG>0

If the Gibbs free energy of the reaction is positive than the reaction will be non spontaneous .

If the Gibbs free energy of the reaction is negative than the reaction will be spontaneous

Gibbs free energy is an energy which that can be use to convert into useful work.

ΔG=ΔH-TΔS

with ΔG= Gibbs free energy

with ΔH = enthalpy of reaction

with T = temperature of eh reaction

ΔS = Entropy change

The reaction A: Pi+glucose⟶glucose-6-phosphate+H2O

The ΔG is positive. This is an nonspontaneous reaction or an unfavorable reaction

The reaction B: Pi+fructose-6-phosphate⟶fructose-1,6-bisphosphate+H2O

The ΔG is positive. This is an nonspontaneous reaction or an unfavorable reaction.

The reaction C: ATP+H2O⟶ADP+Pi

The ΔG is negative. This is a spontaneous reaction or a favorable reaction.

A and B are unfavorable reactions.

What part of the atom determines if it will combine or break apart from other substances

enyata [817]

The combination of an atom with other atom is bonding. Or break apart from other substance is breaking of interaction.

The bonding or interaction (inter-atomic) are due orbitals and electrons present in these orbitals

The atom consists of

a) a central nucleus which has proton and neutrons: they do not take part in chemical reactions

b) the part other than nucleus which has shells, sub shells and orbitals

These orbitals have electrons.

So the outer part of nucleus takes part in any combination with other substance

Which elements have electron configurations that end in ns 2 np 5 ? halogens noble gases inner transition metals transition meta

4vir4ik [10]

HALOGENS have 7 electrons in their final shell regardless if the total number of atoms. These 7 electrons would be shared between the 's' and 'p' orbital in the form ns² np⁵ (the same as the question). Attached is a table that highlights the fact that halogens have the same form in terms of the valence electrons.
