Carbon? i am confused, if you're asking for the element or what is happening, i need a bit of clarification!
The polar molecules dissolve in water, because water is also a polar molecule.
"Like dissolves like".

Answer :
In my opinion , answer is A
Answer:
The vinegar is highly acidic by 100 times than yogurt.
Explanation:
∵ pH = -log[H⁺]
- The concentration of H⁺ in yogurt:
∵ pH = -log[H⁺]
∴ 5 = -log[H⁺]
∴ [H⁺] = 1.0 x 10⁻⁵ M.
- The concentration of H⁺ in vinegar:
∵ pH = -log[H⁺]
∴ 3 = -log[H⁺]
∴ [H⁺] = 1.0 x 10⁻³ M.
the ratio of H⁺ in vinegar to that in yogurt = 1.0 x 10⁻³ M / 1.0 x 10⁻⁵ M = 100.0.
<em>∴ The vinegar is highly acidic by 100 times than yogurt.</em>

<span>No. Radiocarbon dating has an effective range to only about 62,000 years ago (and the further back you go, the higher your error will be). The fossils in the shale are much older than that, so you can be sure that the leaves are not recent enough to be dated that way.</span>
