Answer: Mendeleev improve newlands periodic table because he swapped the order of some elements if that fitted their properties better.
Explanation: I hope this helps!... :)
Explanation:
The idea here is that you need to use the Periodic Table of elements to find the mass number of the most common isotope of phosphorus, P.
Answer:
E) Silver, mass = 420 g, d = 10.5 g/cm.
Explanation:
Hello,
In this case, since the density is defined by:

Given the mass and density, we compute the volume via:

Thus, for each vase we have:
A) 
B) 
C) 
D) 
E) 
In such a way, the largest volume corresponds to E) Silver, mass = 420 g, d = 10.5 g/cm.
Best regards.
