Answer:
B. topsoil is made entirely of decomposed organic remains
Answer:
Please find the structure of the hydrocarbon in the attachment section and details on how to draw it in the explanation section.
Explanation:
Heptane is a member of the alkane group, which has a general formula of CnH2n+2. If n in heptane is 7, this means that the chemical formula for heptane will be C7H16 i.e.
= C7H2(7) + 2
= C7H14+2
= C7H16
C7H16 is the chemical formula for heptane, which is a linear hydrocarbon with 7 carbon atoms and 16 hydrogen atoms. However, in the name of the hydrocarbon compound given in the question: 2,3-dimethylheptane;
- Two methyl groups (CH3) has a substituted two hydrogen atoms specifically at carbon 2 and 3 respectively. Therefore, the new chemical formula of 2,3-dimethylheptane will be: C7H14(CH3)2
Please find the structural formula of the compound; 2,3-dimethylheptane as an attachment.

According to Henry's law:
C = K P when,
C is the solubility of a gas at a constant temperature in a particular solvent.
K is the Henry law constant
p is the pressure of the gas
we have the pressure and the solubility so we will get the K at first:
by substitution:
0.153 = K * 0.37atm
K= 0.4
∴ C when P = 2.4 atm
∴ C = 0.37 * 2.4 atm = 0.888 = 88.8 g/100g H2O
