It is necessary to make a logical system for naming compounds because there are so many of them and thinking of arbitrary random names for each one and then later remembering them all would be impossible. Also, they need to be all recognized and standardized for global use so as to have everyone use the same system.
According to the research, domain is the taxonomic classification level that is the largest or most broad.
<h3>What is domain?</h3>
It is the broadest taxonomic category in which known living things are classified.
In other words, it is the broadest category in which the different kingdoms of life can be organized, according to the classification models that are most widely accepted in the scientific community.
Therefore, we can conclude that according to the research, domain is the taxonomic classification level that is the largest or most broad.

Answer:
1 : 1
Explanation:
We know that the equation is balanced because the number of zinc, hydrogen, sulfur and oxygen atoms are the same in both sides of the equation.
Zn + H2SO4 → ZnSO4 + H2
We can see that there is one molecule for Zn and also one molecule for ZnSO4 (we know this because there are no numbers before the formulas, so the 1 is implied)
That is why the mole ratio of zinc to zinc sulfate is 1 : 1
The number to the left of a chemical formula is called coefficients
Explanation
Coefficient is the number in front of a chemical formula.
It tell how many molecules of a given formula that are involved in a chemical reaction.
in 2H+O→ H2O the coefficient are 2,1,1
that is, 2 in front of H2
1 in front of O
1 in front of H2O
