Answer:
Although all organic compounds contain carbon, and almost all have hydrogen, most of them contain other elements as well. The most common other elements in organic compounds are oxygen, nitrogen, sulfur, and the halogens.
Explanation:
I hope this helped!
I know the answer but let me just make sure that it is correct
The balanced chemical reaction is written as:
<span>4C(s) + S8(s) → 4CS2(l)
We are given the amount of carbon and sulfur to be used in the reaction. We need to determine first the limiting reactant to be able to solve this correctly.
</span>7.70 g C ( 1 mol / 12.01 g) =0.64 mol C
19.7 g S8 ( 1 mol / 256.48 g) = 0.08 mol S8
The limiting reactant would be S8. We use this amount to calculate.
0.08 mol S8 ( 4 mol CS2 / 1 mol S8 ) ( 256.48 g / 1 mol ) = 78.8 g CS2
M H2O = 18 g/mol
In 18 g of water we have 6,02 × 10^23 molecules.
18 g ----- 6,02 × 10^23
36 g ----- x
x = 36 g × 6,02 × 10^23 / 18 g = 12,04 × 10^23 = 1,204 × 10^24
Answer is 1,204 × 10^24
