Now that Snape and Dumbledore has taught you the finer points of hydration calculations they have a slightly more challenging pr
Mrrafil [7]

Answer:

The value of an integer x in the hydrate is 10.

Explanation:

Molarity=\frac{Moles}{Volume(L)}

Molarity of the solution = 0.0366 M

Volume of the solution = 5.00 L

Moles of hydrated sodium carbonate = n

0.0366 M=\frac{n}{5.00 L}

n=0.0366 M\times 5 mol=0.183 mol

Mass of hydrated sodium carbonate = n= 52.2 g

Molar mass of hydrated sodium carbonate = 106 g/mol+x18 g/mol

n=\frac{\text{mass of Compound}}{\text{molar mass of compound}}

0.183 mol=\frac{52.2 g}{106 g/mol+x\times 18 g/mol}

106 g/mol+x\times 18 g/mol=\frac{52.2 g}{0.183 mol}

Solving for x, we get:

x = 9.95 ≈ 10

The value of an integer x in the hydrate is 10.

Explain how an ionic compound forms from these elements.
grin007 [14]

Ionic compounds are formed by the complete transfer of electrons from more electronegative elements to less electronegative elements.

7. <u>Sodium Nitride (Na₃N)</u> is an ionic substance.

8. The ionic formula for <u>Lithium Oxide is Li₂O</u>

9. The <u>compound SrF₂</u>

10. Aluminum Sulfide is a chemical compound with the <u>formula Al₂S₃.</u>

An ionic compound is a chemical compound composed of ions held together via electrostatic forces termed ionic bonding. The compound is neutral standard but includes definitely charged ions known as cations and negatively charged ions known as anions.

An ionic compound is a chemical compound composed of ions held collectively by means of electrostatic forces termed ionic bonding. The compound is neutral normal however consists of positively charged ions known as cations and negatively charged ions referred to as anions. Ionic compounds incorporate ions and are held collectively via the attractive forces of most of the oppositely charged ions.

A molecule in which the central atom forms three single bonds and has one lone pair is said to have a ________ shape.
nignag [31]

Answer : The correct option is, (c) pyramidal

Explanation :

As we are given that a molecule in which the central atom forms three single bonds and has one lone pair that means the central metal atom has 3 bond pairs and 1 lone pair of electrons.

There are total 4 electron pairs. So, the hybridization will be sp^3 and the electronic geometry of the molecule will be tetrahedral.

But as there are three atoms or bonds around the central atom and the fourth position occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be pyramidal.

Hence, correct option is, (c) pyramidal
