Polyatomic ions: $CH_3COO^-$ , $NO_3^-$ , $NH^+$ , $CN^-$ , $Li^+$ , and $OH^-$

Monatomic ions: $Ca^{2+$ , $O^{2-$ , and $Fe^{3+$

<h3>Monoatomic vs Polyatomic Ions</h3>

In chemistry, monoatomic ions are ions that consist of only a single type of atom. They are usually positive or negatively charged and are otherwise known as simple ions. Examples include $Ca^{2+$ , $O^{2-$ , and $Fe^{3+$

Polyatomic ions, on the other hand, are ions that consist of more than one atom, unlike monoatomic ions. The two or more atoms are covalently bonded and the entire structure behaves like a single chemical entity in reactions. Polyatomic ions are otherwise known as molecular ions.

Examples of polyatomic ions are $CH_3COO^-$ , $NO_3^-$ , $NH^+$ , $CN^-$ , $Li^+$ , and $OH^-$

Thus, from the diagram:

Polyatomic ions: $CH_3COO^-$ , $NO_3^-$ , $NH^+$ , $CN^-$ , $Li^+$ , and $OH^-$

Monatomic ions: $Ca^{2+$ , $O^{2-$ , and $Fe^{3+$

Answer:

hola soy jess, tu respuesta esta aqui

¿cuantos moles de CO2 se requiere para reaccionar 2 moles de Ba(OH)2

2 mol Ba(OH)₂ × \frac{1molCO_{2} }{1molBa (OH)_{2}}

1molBa(OH)

1molCO

= 2 moles CO₂
