Explanation:
Usually, when we write a chemical formula for any compound or other chemical specie, we use subscripts to;
- Indicate the ratio of atoms of each element present in the compound or chemical specie
- Show the number of atoms of each element present in the compound or chemical specie.
Hence, the subscripts written after chemical formulas have more than one function as described above.
In H2SO4 for instance, there are two hydrogen atoms, one sulphur atom and four oxygen atoms as shown in the chemical formula.
C I pretty sure it's C but I could be wrong
Answer:
2 atoms of carbon combine with 6 atoms of hydrogen to from ethane.
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
