Answer:
Sodium is higher than Potassium in thesame group
Explanation:
Sodium and potassium are the elements present in the first group of the periodic table. In group, atomic size increases from top to bottom this implies that even atomic radius increases. This causes less attraction force by nucleus on the electrons of outermost orbit of the atom and hence reduces the first ionisation energy, which is the energy required to remove the electron from the outermost orbit of an atom. So, as potassium is below sodium in the group, sodium has greater ionisation energy than potassium

Answer:
127.2 g/cm^3
Explanation:
(Think of the DMV triangle. I'll attach a picture)
Volume = Density x Mass
Volume = 2.12 g/cm3 x 60.0 g
Volume = 127.2 g/cm3

<u>Answer:</u> The products in the given chemical reaction are 
<u>Explanation:</u>
Reactants are defined as the species which react in the reaction and are written on the left side of the reaction arrow.
Products are defined as the species which are produced in the reaction and are written on the right side of the reaction arrow.
For the given chemical equation:

The reactants of the above reaction are
and the products are 
Hence, the products in the given chemical reaction are
