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.

a student reacted 40 drops of an unknown amine with 20 drops of iodomethane in 2 ml of a suitable solvent mixture. after 15 minutes of reaction, a white precipitate formed. the precipitate was isolated and its melting point was recorded to be 178 °c. what could this precipitate be?
The compound formed is the quaternary ammonium salt N,N,N-trimethyl-1-phenylmethanaminium iodide.
Quaternary ammonium salts are formed when methyl iodide reacts with an amine. The quaternary ammonium salt is an ionic substance which often has a high melting point. Remember that the melting point of a substance can be used to identify the substance.
In this case, a student reacted 40 drops of an unknown amine with 20 drops of iodomethane in 2 ml of a suitable solvent mixture. after 15 minutes of reaction, a white precipitate formed. the precipitate was isolated and its melting point was recorded to be 178 °c. This precipitate must be N,N,N-trimethyl-1-phenylmethanaminium iodide (Benzyltrimethylammonium iodide) because it is a quaternary ammonium salt whose melting point is 178 °c.

Regular table salt is sodium chloride, NaCl. It is a bonding of an Na+ ion and a Cl- ion. Which of these ions is bigger?
Answer:
in the periodic table we can see that the ions of Cl is greater than the ions in Na
Cl- ion is bigger than Na+ ion because of the presence of more number of electrons.
The atomic number of sodium+ ion is 10 means it has 10 number of electrons which can accommodate into 2 shells or orbits while on the hand, chlorine- ion has atomic number 18 means it has 18 number of electrons which can be accommodate into 3 shells or orbit.
So there is one shell more in chlorine ion as compared to sodium ion which make the size of chlorine ion large so we can conclude that chlorine ion is bigger than sodium ion.

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

the source of gases for the secondary atmosphere of the earth was _______
The source of gases for the secondary atmosphere of the earth was Volcanic Eruptions.
What is Secondary Atmosphere ?
The scientist think that the atmosphere today is completely different from what it used to be originally and therefore they call it secondary atmosphere.
Internal volcanic activity or the deposit of debris from comet collisions produce a secondary atmosphere.
The secondary atmosphere is thought to have formed as a result of the numerous volcanic eruptions that occurred from the start of Earth's early periods.
Although each volcano is unique, they all emit gases such as H₂O, CO₂, SO₂, H₂S, HCl, N₂, NO₂, and others.
These gases are formed due to melting of the Earth's crust.
Volcanic activity renew the atmosphere's molecules.
These molecules are not the Nitrogen and Oxygen that make up the atmosphere today.

What makes a charged object attract an uncharged object?
The charge in both objects move around.
The charged object is positively charged.
The charges move in the uncharged object.
The uncharged object becomes negatively charged.
Answer:
its c I think C)
The reason for this is due to the phenomenon called "Charging by Induction". What that means is that when something with a charge, for example a negative charge, is brought near an uncharged one, it induces the opposite charge onto it (positive in this case) and therefore since opposites attract, it attracts it.
The reason for this is that since, just like a positive magnet rejects and pushed away like charges, the electrons hold a negative charge, they push away any electrons that may be in the neutrally charged item causing only protons to be left, thus creating an oppositely charged object. Or vice versa.
So whatever charge the object has, it induces the opposite charge into the uncharged object, causing the charges to move only in the uncharged one.
Explanation:
An electrochemical cell was designed using magnesium anode and zinc cathode calculate the EMF of the cell
Will the reaction be spontaneous or not? Give reason for your answer
When the cell potential is positive then the electrochemical reaction is spontaneous. The Ecell is positive when Zn serves as cathode and Mg serves as anode hence the reaction is spontaneous.
An electrochemical cell is any type of cell in which energy is produced by a spontaneous chemical reaction. Redox reactions that occur in an electrochemical cell produce energy.
An electrochemical cell becomes spontaneous only when Ecell is positive. Ecell is positive when a metal that has a more negative electrode potential serves as the anode.
Since Mg has a more negative electrode potential that Zn, it follows that a cell in which Mg is the anode and Zn is the cathode will have a positive Ecell and the reaction will be spontaneous.

Spectroscopy is is an area of science that deals with interaction of matter and the electromagnetic spectrum. Colorimetry can distinguish between a colorless and a colored substance.
The type of spectroscopy that would be a good choice to determine the identity of an unknown sample is a type of spectroscopy that deal with the interaction of visible light with matter.
A type of spectroscopy that deals with interaction of visible light with matter is colorimetry. Colorimetry can measure the concentration of a substance as a function of the amount of light that is absorbed by the substance.
Since NO2 has a reddish brown color, its concentration can be measured using colorimetry. The concentration of N2O4 can not be measured using colorimetry because it is colorless.
