Answer:
The empirical formula is same as the molecular formula = C6H10S2O
Explanation:
we start by dividing the percentage of each of the elements by their atomic mass
Carbon = 44.4/12 = 3.7
Hydrogen = 6.21/1 = 6.21
Sulphur = 39.5/32 = 1.234375
oxygen = 9.89/16 = 0.618125
That of oxygen is smallest so we divide all by that of oxygen
C = 3.7 / 0.618125 = 6
H = 6.21/ 0.618125 = 10
S = 1.234375/ 0.618125 = 2
Automatically, oxygen is 1
So the empirical formula is;
C6H10S2O
Let’s get its molecular formula. We multiply each of the subscript by the number;
(72 + 10 + 64 + 16)n= 162
162n = 162
n = 1
So the molecular formula is same as the empirical formula
Answer:
1. CO₃⁻² + H₂O ⇄ HCO₃⁻ + OH⁻
2. HCO₃⁻ + H₂O ⇄ H₂CO₃ + OH⁻
3. H₂CO₃ → H₂O + CO₂
Basic solution
Explanation:
Brønsted Lowry theory:
Acid → Release a proton
Base → Accept a proton
1. CO₃⁻² + H₂O ⇄ HCO₃⁻ + OH⁻
Carbonate takes a proton from the water
2. HCO₃⁻ + H₂O ⇄ H₂CO₃ + OH⁻
Bicarbonate takesa proton from the water to produce carbonic acid.
3. H₂CO₃ → H₂O + CO₂
Carbonate acid decomposes into CO₂ and H₂O
In the first reaction, when the carbonate takes a proton from the water, water releases OH⁻, so the solution is basic.
THE EXPLINATION ANSWER: I think crude oil is a mixture because it is made up of compounds that can be separated using distillation, a physical process.
