aksik [14]3 years ago
4 0

Explanation:

Some examples of colorful light emissions are street lights, neon signs and, of course, fireworks. Neon signs emit light when an electric current passes through the neon gas.

Predict the sign of ΔS° for 2NO2(g) LaTeX: \longrightarrow⟶ N2O4(g) CaCO3(s) + 2HCl(aq) LaTeX: \longrightarrow⟶ CaCl2(aq) + H2O(
prisoha [69]

Answer: a. 2NO_2(g)\rightarrow N_2O_4(g): \Delta S is negative

b. CaCO_3(s)+2HCl(aq)\rightarrow CaCl_2(aq)+H_2O(l) : \Delta S is negative

c. Ag^+(aq)+Cl^-(aq)\rightarrow AgCl(s): \Delta S is negative

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from  an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa

a)  2NO_2(g)\rightarrow N_2O_4(g)

In this reaction 2 moles of gaseous reactants are converting to 1 mole of gaseous products. The randomness will decrease and hence entropy will also decrease. Thus \Delta S is negative.

b) CaCO_3(s)+2HCl(aq)\rightarrow CaCl_2(aq)+H_2O(l)

In this reaction solid reactants are converting to aqueous products. The randomness will increase and hence entropy will also increase. Thus \Delta S is positive.

c) Ag^+(aq)+Cl^-(aq)\rightarrow AgCl(s)

In this reaction aqueous reactants are converting to solid products. The randomness will decrease and hence entropy will also decrease. Thus \Delta S is negative

What would be the immediate product of neutron absorption by Ag 107
Novosadov [1.4K]

The immediate product of neutron absorption by Ag-107 is silver atom with a mass of 108, Ag-108.

<h3>What is radioactivity?</h3>

Radioactivity is the spontaneous emission of radiation as wall as particles and energy l by the nucleus of elements due to their disintegration.

The radioactive particles that are usually emitted include:

  • alpha particles
  • beta particles and
  • neutrons

The neutron has a mass of 1.

When silver isotope having a mass of 107 absorbs a neutron, the silver isotope produces will have a mass of 108, Ag-108.

Write a chemical equation, clearly showing the stereochemistry of the starting material and the product, for the reaction of (S)
tatuchka [14]

Answer:

(S)−1−iodo−2−methylbutane

Explanation:

This reaction involves the substitution of iodine for bromine in (S)−1−bromo−2−methylbutane. The reaction proceeds with retention of configuration because the product is (S)−1−iodo−2−methylbutane. There is no change in the configuration of the product compound when the reaction is carried out in acetone which is a polar aprotic solvent. The reaction is shown in the image attached.
