Answer:
C.) 2,1,2
Explanation:
You have to balance the equation by getting the number of elements on the left and right side to equal. Before balancing there is one more oxygen on the left side than the right side. You have to change the coefficient in front of H2O to fix this, and that means adding a "2" in front of the H2 to get that to equal as well.
You end up with 2H₂+10₂→ 2H₂O

This is not the best way to organize a periodic table because two elements might have similar atomic mass.
<h3>What is periodic table?</h3>
Periodic table is a chart in which arrangement of chemical elements are done.
In the early periodic table elements are arranged on the basis of their atomic masses, while after sometime Moseley arranged the periodic table on the basis of atomic number as he proposed that properties of an element is justified on the basis of number if electrons.
And mass of two substances may be same so it is difficult to differentiate between them.
Hence, two elements might have similar atomic mass.

Answer:
A)
Explanation:
It estimates the probability of extinction.
The composition of a compound does not vary because it is made up of fix ratio by mass.
<h3>What is compound?</h3>
A compound is a chemical substance that is composed of more than one element that held together by chemical bonds and produces fix ratio by mass so we can conclude that the composition of a compound does not vary because it is made up of fix ratio by mass.
