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.

Hydrogen sulfide gas is combusted with oxygen gas to produce sulfur dioxide gas and water vapour. If there is 48.4 L of oxygen available. What volume of hydrogen sulfide gas may be combusted if the pressure and temperature are held constant?
Answer:
2H2S + 3O2 → 2SO2 + 2H2O

why are some substances such as magnesium and fluoride allowed in drinking water?
Answer:Pure water does not contain fluoride, but much drinking water does contain fluoride that is deliberately added to reduce tooth decay of children who drink the water. Some drinking water supplies also contain fluoride naturally.
Explanation:
in small doses not harmful
Fluoride is a chemical that is intentionally added to drinking water in order to prevent tooth decay in children. Pure water does not naturally contain fluoride. Some sources of drinking water naturally contain fluoride as well.
Why magnesium and fluoride allowed in drinking water?Fluoride is a chemical that is intentionally added to drinking water in order to prevent tooth decay in children. Pure water does not naturally contain fluoride. Some sources of drinking water naturally contain fluoride as well.
Compared to magnesium found in food, magnesium in water is present as hydrated ions, which are more easily absorbed. Thus, the role played by water magnesium in the prevention of magnesium insufficiency may be quite important for people who drink water with high magnesium levels.

atomic no. is 42
chemical symbol is Mo
no. of protons is 42
atomic mass is 95.95
no. of electrons is 42
no. of electron in outer most shell is 1
no of electrons in the n 3 shell is 18
no. of neutron is 96
The element molybdenum is 42nd element in periodic table with the symbol Mo and a mass of 96. It have 42 electrons and 42 protons.
What is Molybdenum?Molybdenum (Mo) is a transition metal in periodic table included in the d-block. The atomic number of molybdenum is 42 which is the number of protons and electrons in it.
The atomic number of a neutral atom is equal to the number of electrons in it. For a neutral atom the number of electrons and protons are equal and thus the number of both electrons and protons in Mo is 42.
Mass number is the sum of number protons and neutrons in an atom. The mass number of Mo is 96 and number of protons is 42. Thus, the number of neutrons is 96 -42 = 54.
The outer shells of Mo are 4d and 5s containing 4 and 2 electrons respectively. Thus the number of outer electrons is 6.The level n= 3 is M shell which contains 18 electrons for Mo.

What describes a chemical reaction?
Answer:
A chemical reaction is a process where two different substances or elements are mixed together. They then undergo some sort of chemical change to become a different substance altogether.
Explanation:
If you were to mass the reactants before a reaction and then mass the products after the reaction what would you expect to find and why?
pls answer fast ill give brainliest!
Answer:
No change...
Explanation:
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

negative ions form when atoms _______ valence electrons.
Answer:
Negatively charged ions are called anions, and an anion is formed when an atom gains an electron. Thus, the atom has an extra charge of electrons,
Explanation:
so it becomes negatively charged.
Negative ions (or anions) are atoms that have gained electrons.
Electrons have a negative charge so if an atom is getting more of them, it's becoming more negative.

a reaction is said to be ________ if the bonds formed during the reaction are stronger than the bonds broken.
Answer:
Exothermic
Explanation:
Bond strength has everything to do with the energy associated with it. What I mean by that, is a stronger bond will require a lot higher of an energy input to break than a weaker bond.
In the same way, energy is released when a bond is made. So, the formation of a stronger bond releases more energy than the formation of a weaker bond.
So, putting the two ideas together, if the bonds formed as stronger than the bonds broken, then more energy is released than taken in, which means energy is released overall over the course of the reaction. This means that the reaction is exothermic.
If there was energy taken in overall, this would be an endothermic reaction.
Let me know if that makes sense, and hope I helped! :)
Exothermic reaction is a reaction in which the bonds formed during the reaction are stronger than the bonds broken.
When chemical reactions occur, there will always be an accompanying energy change.
In exothermic reaction the bonds formed in the products are stronger than the bonds broken in the reactants whereas in endothermic reaction the bonds broken in the reactants are stronger than the bonds formed in the products.
