Answer:- B) Full ionic equation
Explanations:- A molecular equation does not have ions. It is the non charge form of the elements of compounds. When we write the full or total ionic equation for the molecular equation then ions are written for the aqueous species. The ions present on both sides(reactant and product sides) in a full ionic equation are known as spectator ions or common ions. These ions are canceled to get the net ionic equation. For example, reaction of aqueous solution of silver nitrate with aqueous solution of barium chloride to form aqueous solution of barium nitrate and a precipitate of silver chloride.
Balanced molecular equation:-
Full ionic equation:-
If we look at the above full ionic equation then barium ion and nitrate ions are the spectator ions are they are present on both sides.
So, while writing the net ionic equation, these spectator ions are canceled.
Net ionic equation:-
So, it is also clear from the above example that it's the full ionic equation that include spectator ions.
1)Na and O - ion bond
2)K and F - ion bond
3)Ne and O - no bond (as Ne is a noble gas)
And by elimination, your answer is 4)
If you want to optimize environmental impact, the ores should be sifted at the site before transporting.
<h3>What is an ore?</h3>
An ore refers to the raw material from which a material is made. Usually, ores are obtained in the raw state from the earth. Metal ores are very important in the manufacturing industry.
In order to reduce the environmental impact of the manufacturing of ores in the metallurgical industry, the ores should be sifted at the site before transporting.

Answer:
5 atoms
Explanation:
When a chemical reaction starts with 5 atoms of hydrogen, and the reaction goes into completion, it must give us 5 atoms of hydrogen.
This is in compliance with the law of conservation of mass which states that "in a chemical reaction, matter is neither created nor destroyed but converted from one form to another".
In chemical reactions, bonds are broken and new compounds are formed in the process. The same number of species at the start and end of the reaction must still be the same.
Answer:Chromosomal mutations all happen during meiosis. Chromosomes in meiosis have the opportunity to line up and cross over. This mixes up the genetic information from the parents in the sperm or egg. However, during crossing over things can go wrong.
