As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit ___?

Chemistry
1 answer:
Tju [1.3M]3 years ago
6 0

Ans: As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit will <u>increase.</u>

The energy (E) is related to the frequency (ν) by the following equation:

E = hν

where h = planck's constant

The change in energy i between levels is:

ΔΕ = h(Δν)  -----(1)

Based on the above equation, as the changes in energy levels increase, the frequency of emitted radiation will also increase.

Calculate the number of liters in 3.25 g of ammonia
il63 [147K]

 The liters in   3.25 g   of  ammonia  4.28 L


  <u><em>calculation</em></u>

 Step 1: find moles of ammonia

 moles = mass÷ molar  mass

 From  periodic    table  the molar mass  of ammonia (NH₃)  =  14 +(1×3 ) = 17  g/mol

3.25 g÷ 17 g/mol = 0.191   moles

Step 2: find the number of liters of ammonia

 that is at STP  1  moles = 22.4 L

                        0.191 moles = ? L

<em>by cross  multiplication</em>

 ={( 0.191   moles  ×22.4 L) / 1 mole}  = 4.28 L

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.
