<span>The question says,'which is the correct Lewis structure for fluorine, which is a group 7A element. Lewis structure is used to represent the covalent bonding of molecules. Flourine has seven electron in its outermost shell, so the Lewis structure of flourine will have 3 lone pair of dots and a single dot. Each dot represent an electron.</span>

Explanation :

Lewis-dot structure : It is defined as the representation which shows the valence electrons present in an element. The electrons are represented as dots in the structures.

The given element is, fluorine which is a group 7A element.

The atomic number of fluorine is 17 and fluorine has '7' valence electrons.

The dots represent the number of valence electrons.

The Lewis-dot structure of fluorine is shown below.

If this compounds (N2O) molecular mass is 88g are the empirical and molecular formulas the same as one another or different

Softa [21]

Answer:

Explanation:

Let us examine this problem carefully:

Given compound is N₂O

Molecular mass = 88g

Now,

The empirical formula is the simplest formula of a compound.

The molecular formula is the true formula of the compound that shows that actual ratios of the atoms in a compound.

To find if they both have the same molecular and empirical formula, they must have the same molecular mass.

For N₂O;

Molecular mass = 2(14) + 16 = 44g/mole

But the true and given molecular formula of the compound is 88g/mole

This shows that the compound given is the empirical formula of the compound.

Molecular formula:

molecular mass of empirical formula x n = molecular mass of molecular formula

n = $\frac{88}{44}$ = 2

Molecular formula of compound = 2(N₂O) = N₄O₂

Therefore the empirical and molecular formulas are not the same

Helpppppppppppppppppppppppppppppppppppppppppppp

cluponka [151]

Question 1:

Part 1: A rock formed when an already existing rock is subjected to extreme heat and pressure is metamorphic.

Part 2: A rock formed from particles that are deposited and lithified is sedimentary.

Part 3: A rock formed from cooled and hardened magma or lava is igneous.

These are correct. Ironic they are already in the correct order.

~Hope this helps!

What property of a liquid is used when petrol, ( gasoline) is pumped from the tank to the engine of a car? I need answers!!!!

Romashka-Z-Leto [24]

In many modern cars the fuel pump is usually electric and located inside the fuel tank. The pump creates positive pressure in the fuel lines, pushing the gasoline to the engine. The higher gasoline pressure raises the boiling point.

What is mole concept and muscular mass

Fantom [35]

the mole concept :

a mole (mol) is defined as the amount of substance that contains as many atoms, molecules, icons, electrons or any other elementary entities as there are carbon atoms in exactly 12 gm of. the number of atoms in 12gm of is called Avogadro's number.

I'm not sure about muscular mass sorryyyy

Which compound could serve as a reactant in a neutralization reaction ?

Veseljchak [2.6K]

The compound that could serve as a reactant in the neutralization reaction is H2SO4

Explanation
Neutralization reaction occur between an acids and a base. H2SO4 ( sulfuric acid) is a strong acid. It can be neutralized by strong base such as NaOH ( sodium hydroxide)

Example of neutralization reaction is

2NaOH + H2SO4 → Na2SO4 + 2H2O
