Answer:
47,9 kJ/g
Explanation:
The enthalpy of combustion is the change in energy due the reaction of combustion of n-octane. If the enthalpy is -4,79x10⁷ J/kg And knowing (1000J = 1kJ) (1000g = 1kg). The enthalpy of combustion expressed in kJ/g is:
= <em>47,9kJ/g</em>

I hope it helps!
Does this one help or do you need a different one?
Answer:
very confused but, hope this helps in a way-:
What can be the Results and conclusion to this experiment?
1) Observation: Plants grow well in the ant habitats.
2) Question: Does ants help in plant's growth?
3) Hypothesis: There is a mutualistic relationship between plants and ants.
4) Experiment: This hypothesis can be experimented using ecological study design. The growth of two plants, one growing in the presence of ants and the other in the absence of ants are compared. All other variables like temperature, moisture, soil and nutrients are maintained constant. The growth in plants are measured after two months. It will be observed that the growth of plants in the presence of ants is more than the other plant. Ants help in aerating the soil and protects the plant from herbivores, and fungal attack.
A) It decreases because the distance between the nucleus and outermost shell increases
