Answer: The chemical formula for dinitrogen tetraoxide is $N_{2}O_{4}$ . This is a covalent compound, therefore, it uses prefixes (e.g. di-, tetra-) to indicate the number of atoms of each element present in the compound.

Further Explanation:

Covalent compounds are compounds made up of two or more non-metal elements. Non-metals are those that appear to the right of the zigzag line on the Periodic Table of Elements. Ionic compounds, on the other hand, are compounds that are made up of metal and non-metal elements. Metals are the elements found to the left of the zigzag line on the Periodic Table. Naming of ionic and covalent compounds are different.

Dinitrogen tetraoxide is a covalent compound because it consists of nitrogen (N) and oxygen (O) atoms which are both non-metals.

The following prefixes added before the name of each element in a covalent compound:

di - 2

tri - 3

tetra - 4

penta - 5

hexa - 6

hepta - 7

octa - 8

nona - 9

deca - 10

The last part of the second element is changed to - IDE for binary compounds (compounds made up of only two types of atoms). If it is a ternary compound and one element is oxygen, the last part of the second element (other than oxygen) is changed to -ATE.

1. Sodium and water react according to the following equation. If 31.5g of sodium are added to excess water, how many liters of

Vika [28.1K]

<h3> Question 1</h3>

The number of liter of hydrogen gas that are formed at STP is

15.344 L

<u><em> calculation</em></u>

calculate the moles of Na

moles =mass/molar mass

from periodic table the molar mass of Na = 23 g/mol

moles = 31.5 g /23 g /mol = 1.37 moles

From equation above the mole ratio of Na: H2 is 2:1

therefore the moles of H2 =1.37 x1/2 =0.685 moles

At STP 1 moles of a gas = 22.4 L

0.685 moles = ? L

by cross multiplication

=[ (0.685 moles x 22.4 L) / 1 mole =15.344 L

<h3> Question 2</h3>

The percent yield = 84.77%

<u><em>calculation</em></u>

4 Na + O₂ → 2 Na₂O

%yield =actual yield / theoretical yield x 100

Actual yield= 61.8 g

<em>The theoretical yield is calculated as below</em>

Step 1: find the moles of Na

moles = mass /molar mass

from periodic table the molar mass of Na = 23 g/mol

moles = 54.1 g /23 g/mol =2.352 moles

Step 2: use the mole ratio to determine the moles of Na₂O

Na:Na₂O is 4: 2 therefore the moles of Na₂O = 2.352 x 2/4 =1.176 moles

Step 3: find the theoretical mass of Na₂O

mass = moles x molar mass

The molar mass of Na₂O = [(23 x 2 ) + 16] =62 g/mol

mass = 1.176 moles x 62 g/mol = 72.9 g

% yield is therefore = 61.8 g /72.9 x 100 = 84.77%

At 45.2 L cylinder containing C2H2F4 at a pressure of 3.00 atm is connected by the valve to 4060 mL cylinder containing N2H4 at

puteri [66]

The partial pressure of the N2H4 gas is 1.50 atm.

<h3>Dalton's law of partial pressure</h3>

From the Dalton's law of partial pressure, the total pressure of a mixture of gases is the sum of the individual partial pressures of all the gases present in the mixture.

We have the following;

C2H2F4 = 3.00 atm

N2H4 = c

Total pressure = 3.00 atm + 1.50 atm = 4.50 atm

Hence, the partial pressure of the N2H4 is N2H4.

Answer:

Explanation:

Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.

Give the following for SO2 and BrF5:

frosja888 [35]

Answer:

The given molecules are SO2 and BrF5.

Explanation:

Consider the molecule SO2:

The central atom is S.

The number of domains on S in this molecule is three.

Domain geometry is trigonal planar.

But there is a lone pair on the central atom.

So, according to VSEPR theory,

the molecular geometry becomes bent or V-shape.

Hybridization on the central atom is

$sp^{2}$ .

Consider the molecule BrF5:

The central atom is Br.

The number of domains on the central atom is six.

Domain geometry is octahedral.

But the central atom has a lone pair of electrons.

So, the molecular geometry becomes square pyramidal.

The hybridization of the central atom is $sp^{3} d^{2}$ .

The shapes of SO2 and BrF5 are shown below:
