. Describe the differences and similarities between the molecules of carbon monoxide, diatomic oxygen and carbon dioxide. Which two appear most alike?

Answers

Explanation:

Though both the molecules contain carbon and oxygen, the general difference between them lies in their number of oxygen of atoms carried by them; as carbon dioxide (CO2) has one carbon atom and two oxygen atoms, while carbon monoxide (CO) has one carbon and one oxygen atom.

Carbon Dioxide is naturally present in our atmosphere and as it is excreted out during the process breathing by the animals and humans. On the other hand, Carbon Monoxide is toxic, and it produces suffocation if it builds while incomplete combustion of coal, fossil fuels, etc.

In the layman language, both the terms are sometimes used interchangeably and create confusion. As they have few similarities and incorporates carbon and oxygen as well, and are the byproducts of the things which carry carbon like fuels, coals, woods, and natural gas.

We all are aware of the three states of matter, which are Solid, Liquid and Gas. In this context, we will be discussing the two most common gases present in our atmosphere, how they vary from each other, their effects and their similarities. These gases are Carbon Dioxide and Carbon Monoxide.

Answer:

The major similarities between molecules of carbon monoxide, diatomic oxygen and carbon dioxide is that they all exist in gaseous states in their natural forms. Each of them also have low molecular weight of less than 70g/mol.

The difference between them is that the carbon monoxide is formed from incomplete combustion and is a toxic gas while carbon dioxide is an end product of respiration and is used by plants for photosynthesis. Oxygen on the other hand is essential for respiration and is the end product of photosynthesis.

Carbon dioxide and Carbon monoxide look most alike as they have the same elements which include Carbon and Oxygen but only different in the number of atom composition

Each of these Ionic Compounds are named INCORRECTLY.

1. Find and describe the mistake
2. Correctly name the compound.

CaCl2 - Calcium Chlorine

CuS - Copper Sulfide

Li3P - Trilithium Phosphide

CuBr - Copper(II) Bromide

NaOH - Sodium Hydrogen Oxide

Answers

Explanation:

The nomenclature of ionic compounds is given by:

1. Positive is written first.  And if the metal atom has various oxidation states then its oxidation state is to be mentioned in brackets with help of roman numbers

2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

1.)  : Calcium chloride  (Correct)

In the given compound, calcium has oxidation state of +2 and chlorine has oxidation state of -1.The name is correct.

2.)  : Copper (II) oxide   (Incorrect)

In the given compound,copper has the oxidation state of +1 and oxygen has oxidation state of -2.So ,the correct name will be Copper (I) oxide.

3.)  : Lead (II) sulfide   (Incorrect)

In the given compound, lead has the oxidation state of +4 and sulfur has oxidation state of -2. So ,the correct name will be Lead (IV) sulfide.

Type the formula "H2" into the Reactants box. What is the molar mass of hydrogen gas, H2?

Answers

1.01 x 2 = 2.02 equals the molar mass of H2.

The molar mass of hydrogen gas H₂ is 2.016 grams.

What is molar mass?

The mass of a substance divided by its concentration, expressed in grams per mole (g/mol), is known as its molar mass.

Mass is the quantity of matter in a physical body. The product of the molar mass of the compound and the moles of the substance are defined as mass.

The mole is a SI unit of measurement that is used to calculate the quantity of any substance.

M = m /n

M = molar mass

m = mass of a substance (in grams)

n = number of moles of a substance

The mass of hydrogen is 1

The number of moles of hydrogen is 6.022 x 10²³

Hydrogen gas has a molar mass of 2.016 grams per mole. When two hydrogen atoms join forces to create a molecule with the formula H2, hydrogen gas is created.

Therefore, the molar mass of hydrogen gas H₂ is 2.016 grams

How many grams are in 2.5 moles of dicarbon hexahydride?
Round to 2 significant figures!

Answers

There are 75 grams in 2.5 moles of dicarbon hexahydride (C₂H₆).

The given parameters;

dicarbon hexahydride = [tex]C_2H_6[/tex] number of moles of the dicarbon hexahydride = 2.5 moles

The molecular mass of dicarbon hexahydride is calculated as follows;

Mw = C₂H₆ = (2 x 12) + (6 x 1)

Mw =30 g/mol

The mass of the dicarbon hexahydride in the given number of moles is calculated as follows;

mass = n x Mw

mass = 2.5 x 30

mass = 75 g

Thus, we can conclude that there are 75 grams in 2.5 moles of dicarbon hexahydride (C₂H₆).

Two H are written with a horizontal straight line between them. (H-H)

What does this image represent?

Linear molecule with one domain
Linear molecule with two domains
Tetrahedral molecule with four domains
Trigonal planar molecule with three domains

Answers

Explanation:

It is known that an electron pair represents a domain. Hybridization of BF_{3}BF3 will be calculated as follows.

       Hybridization = \frac{1}{2}[\text{Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge}]21[Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge]

Valence electrons of boron are 3 and no. of bonded atoms in a BF_{3}BF3 molecule is 3.

Therefore, calculate hybridization of BF_{3}BF3 as follows.

          Hybridization = \frac{1}{2}[\text{Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge}]21[Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge]

                              = \frac{1}{2}[3 + 3 + 0]21[3+3+0]

                               = 3

Hence, hybridization of BF_{3}BF3 is sp^{2}sp2 , that is, trigonal planar.

Thus, we can conclude that the given image represents that it is a trigonal planar molecule with three domains.        

Answer:

electron pair => 1 covalent bond => same as H:H

Explanation:

The bar notation is generally accepted as a pair of electrons depicting a 'single' chemical bond. If two bars are shown (e.g; C=C) then two chemical bonds are represented. If three bars are shown (e.g; N≡N) then three chemical bonds are represented. This is the highest number of bonds that can exist between two elements. Hope this helps. :-)

which reagents are appropriate to carry out the conversion shown?

Answers

A reagent us a chemical substance applied in a chemical reaction to bring about a change in the chemical reaction process. The reagent that is appropriate to carry out the conversion is Ethanol (CH3CH2OH).

Organic Reactions are reactions taking place in organic compounds and they can take various forms such as electrophilic addition reaction or nucleophilic substitution reactions.

From the assumed diagram below, the reaction takes place in an unimolecular nucleophilic reaction SN1 mechanism in which a racemic mixture produce an organic compound and an enantiomer.

For the reaction to take place, the best organic reagent to us is known as ethanol (CH3CH2OH). This is because the organic reagent is a solvent that acts as a Nucleophile.

In the reaction, bromine (Br) is the leaving group, after it detaches from the racemic compound, it forms a carbonation in which the Ethanol CH3CH2OH attacks at the carbonation site.

Therefore, we can conclude that the Reagent necessary to carry out the conversion is Ethanol (CH3CH2OH)

What is the most abundant type of protein in egg white? What do you think its purpose is?​

Answers

Answer: Ovalbumin (Albumin)

Explanation:

The albumen (egg white) is composed of almost 60% of the protein ovalbumin. It's the main source of proteins for tissue synthesis in the embryo. It acts as a storage protein, storing ions and amino acids necessary for embryonic development.

There are four different proteins present in egg white. In which the most abundant protein is ovalbumin present in 54 %.  

What are proteins?

Proteins are biomolecules very essential for life. Proteins are made of a number of amino acids.  Amino acids join together to form peptides and large number of peptides constitute a protein.

Essential amino acids have to be up taken from diet and non-essential will be produced inside the body.

Proteins are the major substances to build up our body. There are essential and non essential amino acids. Nails and hair are made of keratin protein. Milk contains the protein called lactine.

Similarly the protein in curd is casein. The proteins in egg white are ovalbumin, ovotransferrin, ovomucin and ovomucoid. In which ovalbumin is most abundant.
