Answer:
Periodic table, in full periodic table of the elements, in chemistry, the organized array of all the chemical elements in order of increasing atomic number—i.e., the total number of protons in the atomic nucleus. ... Mendeleyev in the mid-19th century, has been of inestimable value in the development of chemistry.
Explanation:
1) (1.00mol H2O2)(34.02g/mol H2O2) = 34.02g H2O2
2) (1.00mol NaNO3)(84.99g/mol NaNO3) = 84.99g NaNO3
3) (8.00mol Ar)(6.02x10²³) = 4.82x10²⁴ atoms
4) (132g Kr) / (83.79g/mol Kr) = 1.58mol Kr
5) (96.4g Si)/(28.09 g/mol Si) = 3.43mol Si
(3.43mol Si)(6.02x10²³) = 2.07x10²⁴ atoms Si
6) You did this one correctly :)
Answer:
it is expected that highest melting points correspond to compound with high molecular weight with more force of attractions within the moleules
