Answer:

The correct answer is option c.

Explanation:

Molecularity is defined as number of atoms , ions or molecules that must collide with one another so as to result in a chemical reaction.It is simply the sum of molecules of different reactants as represented in balanced chemical equation.

Reaction taking place in one step are said to be elementary reaction.

Reaction taking place in more than one step are said to be complex reaction.

A mechanism for the decomposition of ozone is given as:

1) O_3 \rightarrow O_2 + O

Molecularity for the first elementary reaction is 1. This because single ozone molecule is present.

2) O + O3\rightarrow O_2 + O_2

Molecularity for the second elementary reaction is 2. This because single ozone molecule reacts with 1 oxygen atom.

What do radio waves and gamma rays have in common?
padilas [110]

Answer: The sequence from longest wavelength (radio waves) to shortest wavelength (gamma rays) is also a sequence in energy from lowest energy to highest energy. ... The energy carried by a radio wave is low, while the energy carried by a gamma ray is high. Different materials can block different types of light.

Copper oxide, CuO, reacts with hydrochloric acid, HCI, to produce copper chloride, CuCL2 and water
spayn [35]

Explanation:

El óxido de cobre (II), también llamado antiguamente óxido cúprico ({\displaystyle {\ce {CuO}}}{\displaystyle {\ce {CuO}}}), es el óxido de cobre con mayor número de oxidación. Como mineral se conoce como tenorita.

{\displaystyle {\ce {2Cu + O2 = 2CuO}}}{\displaystyle {\ce {2Cu + O2 = 2CuO}}}

Aquí, se forma junto con algo de óxido de cobre (I) como un producto lateral, por lo que es mejor prepararlo por calentamiento de nitrato de cobre (II), hidróxido de cobre (II) o carbonato de cobre (II):

{\displaystyle {\ce {2 Cu(NO3)2 = 2 CuO + 4 NO2+ O2}}}{\displaystyle {\ce {2 Cu(NO3)2 = 2 CuO + 4 NO2+ O2}}}

{\displaystyle {\ce {Cu(OH)2 (s) = CuO (s) + H2O (l)}}}{\displaystyle {\ce {Cu(OH)2 (s) = CuO (s) + H2O (l)}}}

{\displaystyle {\ce {CuCO3 = CuO + CO2}}}{\displaystyle {\ce {CuCO3 = CuO + CO2}}}

El óxido de cobre (II) es un óxido básico, así se disuelve en ácidos minerales tales como el ácido clorhídrico, el ácido sulfúrico o el ácido nítrico para dar las correspondientes sales de cobre (II):

{\displaystyle {\ce {CuO + 2 HNO3 = Cu(NO3)2 + H2O}}}{\displaystyle {\ce {CuO + 2 HNO3 = Cu(NO3)2 + H2O}}}

{\displaystyle {\ce {CuO + 2 HCl =CuCl2 + H2O}}}{\displaystyle {\ce {CuO + 2 HCl =CuCl2 + H2O}}}

{\displaystyle {\ce {CuO + H2SO4 = CuSO4 + H2O}}}{\displaystyle {\ce {CuO + H2SO4 = CuSO4 + H2O}}}

Reacciona con álcali concentrado para formar las correspondientes sales cuprato.

{\displaystyle {\ce {3 XOH + CuO + H2O = X3[Cu(OH)6]}}}{\displaystyle {\ce {3 XOH + CuO + H2O = X3[Cu(OH)6]}}}

Puede reducirse a cobre metálico usando hidrógeno o monóxido de carbono:

{\displaystyle {\ce {CuO + H2 = Cu + H2O}}}{\displaystyle {\ce {CuO + H2 = Cu + H2O}}}

{\displaystyle {\ce {CuO + CO = Cu + CO2}}}{\displaystyle {\ce {CuO + CO = Cu + CO2}}}

An ionic bond is a bond that forms between
Morgarella [4.7K]

Answer:  An ionic bond is a bond that forms between ions with opposite charges.

Explanation:

A chemical bond formed by the transfer of electrons from one atom to another is called an ionic bond.

For example, sodium has electronic distribution as 2, 8, 1 and chlorine has electronic distribution as 2, 8, 7.

In order to attain stability, sodium needs to lose 1 electron and chlorine needs to gain one electron. Therefore, sodium will transfer its one valence electron (forming Na^{+} ion) to chlorine atom (forming Cl^{-} ion) which leads to the formation of NaCl compound.

Thus, we can conclude that an ionic bond is a bond that forms between ions with opposite charges.
