Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms ,and because the carbon atom is just the right ,small size to fit in comfortably as parts of a very large molecules.
Answer:
The molecular equation for the reaction of CaCO₃ with CH₃COOH is:
CaCO₃ (s) + 2CH₃COOH (aq) → Ca(CH₃COO)₂ (aq) + H₂O (l) + CO₂ (g)
Option 1
Explanation:
CaCO₃ + 2CH₃COOH → Ca(CH₃COO)₂ + H₂O + CO₂
Option 3 is the same equation as option 1, but calcium acetate, does not precipitate, so the formed salt, is not a solid.
Option 2 and 4 are wrong because calcium acetate molecular formula is
Ca(CH₃COO)₂
Ca(CH₃COO)₂ → Ca²⁺ + 2 CH₃COO⁻
Answer: The answer is 162g.
Explanation: To calculate the mass of a molecule, you have to find the molar mass of each element of the molecule.
Molar mass of C = 12g/mol
Molar mass of H = 1g/mol
Molar mass of O = 16g/mol
Molar mass of S = 32g/mol
From the allicin's formula, there are:
6 C = 6.12 = 72
10 H = 10.1 = 10
1 O = 1.16 = 16
2 S = 2.32 = 64
Adding them up:
C6H10OS2 = 72+10+16+64 = 162g/mol.
As it is requested 1 mol of allicin, it has 162g.

Molar mass of HF = 20.01 g/mol
1 mole HF --------------- 20.01 g
mole HF ------------------ 25.2 g
mole HF = 25.2 / 20.01
= 1.259 moles
