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.

The estimated costs for remodelling the interior of an apartment are: three 1-gallon cans of paint at $15.44 each, two paint bru
Vlad1618 [11]

The total estimated cost with the appropriate significant figures is

$195,13.

Any two non-zero digits that are separated by a zero are important. For instance, the number 108.0097 has seven significant digits. Every zero that is both to the right and left of a non-zero digit and the decimal point is never meaningful. For instance, the number 0.00798 had three significant digits.

Simply multiply the required number of goods by their individual costs, then add them all up to calculate this:

3*13,69= 41,07 2*9,53=19,06 \s1*135= 135

Total cost: $41,07 plus $19,06 plus 135 equals $55,13.

Thus, the overall price will be $195,13.
