well you can't walk through the air but you can't walk through a concrete wall because all of the solid atoms holding it together
From the equation above the reacting ratio of KClO3 to O2 is 2:3 therefore the number of moles of oxygen produced is ( 4 x3)/2 = 6 moles since four moles of KClO3 was consumed
mass=relative formula mass x number of moles
That is 32g/mol x 6 moles =192grams
Sedimentary and metamorphic :)
i hope this helps!!
not sure but h = hydrogen and o = oxygen
