i think A but if I'm wrong sorry
then if increasing then becoming spread out so letter A
Answer : The thermal energy produced during the complete combustion of one mole of cymene is -7193 kJ/mole
Explanation :
First we have to calculate the heat released by the combustion.

where,
q = heat released = ?
= specific heat of calorimeter = 
= change in temperature = 
Now put all the given values in the above formula, we get:


Thus, the heat released by the combustion = 70.43 kJ
Now we have to calculate the molar enthalpy combustion.

where,
= molar enthalpy combustion = ?
q = heat released = 70.43 kJ
n = number of moles cymene = 

Therefore, the thermal energy produced during the complete combustion of one mole of cymene is -7193 kJ/mole
Ecologists use food web diagrams as tools in their studies of different populations of organisms within an ecosystem because it shows the feeding relationship between organisms in the ecosystem.
<h3>What is a Food web?</h3>
This is defined as the graphical representation of the feeding relationship which occurs between organisms in the ecosystem and helps to predict the outcome in the addition or removal of a species.
The food web also helps to determine the various ways in which energy flows and it usually starts from the producers which are the plants as a result of their photosynthetic ability which involves the conversion of solar energy to chemical energy.
There are various organisms in the ecosystem and the food web helps to provide a better understanding of their feeding habits and impact various factors will result in.

Yes , it does become massive and it also becomes heavier.
Fe2O3 + 3CO --------> 2Fe + CO2
1 : 3 : 2 : 3
13.3 <--- 40 ------> 26.6 ---> 40 ( mol)
n = m/M
m CO2 = n.M = 13.3 . 40 = 532 ( g)
p/s : i hope that this will help ( cause i'm not really good at english :}}} )
