Is C2H7 ionic or covalent? <br><br> what would you name NO4? <br><br> what would you name MgCl2?
Vlad [161]

C₂H₇ is a covalent compound

N0₄ will be name nitrogen(viii) oxide

MgCl₂ will be named magnesium chloride.

<h3>What are covalent compounds? </h3>

Covalent compounds are compounds which are formed when two electronegative atoms combine together by a sharing of electrons between them.

Covalent compound molecules are usually formed from a combination of non-metals.

The C₂H₇ is a covalent radical formed from the addition of a hydrogen ions to the covalent compound C₂H₆

<h3>What would you name NO₄?</h3>

The name given to a compound depends on the oxidation number of the component elements.

The oxidation number of oxygen is -2.

Since there are 4 atoms of oxygen, the total negative charge is -8.

Nitrogen will have to exist in the +8 state in order to give a neutral compounds.

Therefore, the name given to the compound will be nitrogen (viii) oxide.

<h3>What would you name MgCl₂? </h3>

Magnesium chloride, MgCl₂  is an ionic compound formed from the ionic bond between chlorine and magnesium.

Magnesium donates two electrons to two chlorine atoms to form magnesium chloride, MgCl₂.

How many moles are in 2.6 x 10 ^25 atoms of Li?​
Cerrena [4.2K]

Answer:

43 mole

Explanation:

Given data:

Number of atoms of Li = 2.6× 10²⁵ atoms

Number of moles = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

2.6× 10²⁵ atoms × 1 mole / 6.022 × 10²³ atoms

0.43 × 10² mole

43 mole
