In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.
Answer:
2KClO3 ==> 2 KCl + 3O2
393g O2 x 1 mole/32 g = 12.28 moles O2
moles KClO3 needed = 12.28 mol O2 x 2 mol KClO3/3mol O2 = 8.19 mol
grams KClO3 = 8.19 moles x 123g/mol = 1007g

Answer:
C=1
A=2
F=3
E=4
