C5H12 (l) + 8O2 (g) ----> 5CO2 (g) + 6H2O (l)
Delta H = -3505.8 kJ/mol
C (s) + O2 (g) -----> CO2 (g)
Delta H = -393.5 kJ/mol
H2 (g) + (1/2)O2 (g) ------> H2O (l)
Delta H = -286 kJ/mol
Possible answers:
a. +35 kJ/mol
b. + 1,073 kJ/mol
c. -4,185 kJ/mol
d. -2,826 kJ/mol
e. -178 kJ/mol
Baking soda is a bicarbonate, which means that each molecule of baking soda
contains a sodium atom, a H atom, an O2 atom, and a CO2 molecule.
Vinegar contains acetic acid, and each molecule contains a H atom, and an acetate ion.
When they're combined, the hydrogen atom in the acetic acid meets up with the H and O2 atoms in the baking soda to form a molecule of water, while the acetate ion grabs onto the sodium atom and forms a salt, sodium, acetate. The CO2 molecule, free of its other chemical bonds, can now escape, and bubbles form as a gas.
Answer:
2,3-dimethylheptane.
CH₃ - CH - CH-CH₂-CH₂-CH₂-CH₂

CH₃ CH₃
Explanation:
Hello there!
In this case, according to the given instructions, it is possible to draw the organic chemical structure by connecting seven carbon atoms along the parent chain with two methyl substituents at the second and third carbon atoms; thus, the resulting structure is:
CH₃ - CH - CH-CH₂-CH₂-CH₂-CH₂
| |
CH₃ CH₃
Furthermore, the name would be 2,3-dimethylheptane according to the IUPAC rules for nomenclature.
Best regards!
