The states of matter that has a defined value but an undefined shape are liquids and gases. Hope this helps, have a BLESSED DAY!
Its a reactant, comes on the left side of the yielding arrow.
Solution:
˙When we go down in periodic table, atomic radii increase.
As atomic radius increases, the Coulomb force, which binds electron to nucleus, decreases.²
This means that it takes less energy to rip an electron from the atom (ionize it).
This is the required reason.
Divide each wight by the relative atomic mass
C = 216 / 12 = 18
H = 36 / 1 = 36
O = 288/16 = 18
Ratio of C:h:O = 1:2:1
Empirical formula is CH2O Could be formaldehyde HCHO.
