Oxidizing acids, such as nitric acid, can explode when mixed with what type of incompatible chemical? air water organic chemical
maxonik [38]

Oxidizing acids, such as nitric acid, can explode when mixed with what type of incompatible chemicals like alcohol, or charcoal.

An oxidizing acid is a Brønsted acid that is a strong oxidizing agent. most Brønsted acids can act as oxidizing agents because the acidic proton can be reduced to hydrogen gas. a few acids include other structures that act as stronger oxidizing agents than hydrogen ions.

Oxidizing acids include concentrated perchloric acid, nitric acid, iodic acid, chromic acid, and the glass cleansing mixture of chromium trioxide and sulfuric acid.

The formation of CsCl from Cs(s) and Cl2 (g) involves the following steps:
scoray [572]

Explanation:

1) Cs(s)\rightarrow Cs(g)

Energy will be absorbed by the Cs(s) to get converted into Cs(g). In order to break the strong association of particles present in solid to convert it into gaseous state energy will be needed. So, energy will be absorbed by the Cs solid in this reaction.

2) \frac{1}{2}Cl_2(g)\rightarrow Cl(g)

Energy will be absorbed by Cl_2 gas in order to break bond between two Cl atoms to form isolated(alone) single chlorine atom.So, the energy will be absorbed by the chlorine gas molecule in this reaction.

3) Cs(g)\rightarrow Cs^+(g)+e^-

Energy will be absorbed by the Cs(g) to get converted into Cs^+(g) cation. In order to remove an electron from the outer most shell of Cs atom energy will be required by Cs atom, So, energy will be absorbed in this reaction.

4) Cl(g)+e^-\rightarrow Cl^-(g)

Energy will get release in formation of Cl^- anion from Cl atom in gaseous state. Chlorine atom need one electron to attain noble gas configuration. So, when an electron is added to the outer most shell of chlorine it attains stability of fully filled outermost shell by which it releases energy on addition of an electron.

5) Cs^+(g)+Cl^-(g)\rightarrow CsCl(s)

Energy will get release on formation of CsCl(s) fromCs^+ cation and Cl^- anion. since both are oppositely charged ion and due to strong electrostatic interaction will get converted into stable molecule of CsCl (s) with release in an energy.

Consider the balanced equation below.
wolverine [178]

Answer:

a) H2S:SO2 = 2:2 and O2:H2O = 3:2

Explanation:

  • 2H2S + 3O2 → 2SO2 + 2H2O

⇒ H2S:SO2 = 2 mol H2S / 2 mol SO2 ≡ 2 : 2

⇒ O2:H2O = 3 mol O2 / 2 mol H2O ≡ 3 : 2
