In 1869 he published a table of the elements organized by increasing atomic mass.
Mendeleev is called the "father of the modern periodic table
stated that if the atomic weight of an element caused it to be placed in the wrong group, then the weight must be wrong. (He corrected the atomic masses of Be, In, and U)
was so confident in his table that he used it to predict the physical properties of three elements that were yet unknown.
After the discovery of these unknown elements between 1874 and 1885, and the fact that Mendeleev's predictions for Sc, Ga, and Ge were amazingly close to the actual values, his table was generally accepted.
However, in spite of Mendeleev's great achievement, problems arose when new elements were discovered and more accurate atomic weights determined.

Why does the Law of Composition mainly applies to compounds?
Answer:
Option C:- Not Change is the correct answer for this question.
Explanation:
Here, the reason for the above answer is explained:-
Potential Ones:- KNO3 and H20 are totally soluble.
Thus the ion concentration remains same and therefore it would not shift in
- Option A:- It would not increase because they both have same concentration that is why this option is incorrect
- Option B:- It would not decrease also because of the same concentration and that is why this option is also incorrect
This is the reason that the "option c "is correct that is it would not change because they both are completely soluble and have the same concentration.
Answer:
This did not change the latex/composition of the balloon it just filled and went out.
Explanation:
Its the same way you fill a container without it being a chemical change.
