8 0

Answer:

The mass of the object would be 491.55g/mL. Hope this helped! :)

Explanation:

D= 7.25g/mL                                                           M=D•V

V= 67.8mL

M=7.25g/mL•67.8mL

M= 491.55g

Which statements describe polyatomic ions? Check all that apply.
Leya [2.2K]

<em>Statements describe polyatomic ions</em>

<em>-Polyatomic ions have many charges.</em>

<em>-Polyatomic ions attract other ions to form ionic bonds.</em>

<em>-Polyatomic ions are made up of two or more types of atoms.</em>

<em></em>

<h3><em>Further explanation</em></h3>

The terms atom, ion, element and compound are used in chemistry

• Atom is the smallest material consisting of a nucleus, which contains protons, neutrons, and electrons, Atom is neutral or not charged.

An element can be an atom or element molecule. Atoms such as Ag (argon), Fe (Iron). If it is a molecule, it ‘ll be an atomic combination of the same type, for example: O₂,

• Molecules are neutral particles consisting of two or more atoms , it can be a same or different

- If it is consists of atoms of the same element is called the Element molecule, for example: N₂, Cl₂

- If it consists of different types of element atoms called Compound molecules, for example: H₂SO₄, NaOH

Monatomic molecules are single atoms that are not bound to other atoms such as elements for example  He gas (Helium) or Ag (Argon)

Diatomic molecules are molecules formed from two atoms such as elemental molecules N₂, H₂, Cl₂, F₂

• Ions are electrically charged atoms. Informing ions, an atom will release or bind electrons.

Atoms with low ionization energy (especially from groups IA or IIA in the periodic system will tend to release electrons, whereas atoms with large electron affinity energy, especially groups VIA or VIIA will tend to bind electrons

This is where ion bonds will occur because of the attractive attraction between negative ions and positive ions

Ions which are positively charged are called cations, while negatively charged ions are called anions.

Ions that have one atom are called single ions, while 2 atoms or more are called polyatomic ions

So atoms can release and bind electrons so that they form ions

Example:

single ion: Na⁺, Al³⁺, Ca²⁺, F⁻, S²⁻

poly atomic ion: SO₄²⁻, NO₃⁻, PO₄³⁻

So the correct answer is:

Polyatomic ions have many charges.

Polyatomic ions attract other ions to form ionic bonds.

Polyatomic ions are made up of two or more types of atoms.
