Answer:
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.
Answer:
A nonspontaneous process
Explanation:
The spontaneity of a reaction is given by the standard Gibbs free energy (ΔG°). We can calculate ΔG° using the following expression.
ΔG° = ∑np . ΔG°f(p) - ∑nr . ΔG°f(r)
where,
ni are the moles of reactants and products
ΔG°f(p) are the standard Gibbs free energies of formation of reactants and products
For the equation,
CO₂(g) → CO₂(aq)
ΔG° = 1 mol × ΔG°f(CO₂(aq)) - 1 mol × ΔG°f(CO₂(g))
ΔG° = 1 mol × (-386.0 kJ/mol) - 1 mol × (-394.4 kJ/mol)
ΔG° = 8.4 kJ
By convention, ΔG° > 0 means that the reaction is nonspontaneous.
Answer:
CH4
Explanation:
The ideal gas behavior of individual gases often depend on the magnitude of intermolecular interaction between the molecules of the gas as well as the presence or absence of polar bonds.
In CCl4, there are polar bonds and the presence of the more electronegative chlorine atom in the molecule and consequently a greater degree of intermolecular interaction at 400K compared to CH4 which contains only non polar bonds.
Therefore, CH4 displays greater ideal gas behavior at 400K than CCl4.
Yes, if you look at the molecular structure of ethanol, or even just evaluate the name you should be able to predict that ethanol will burn, thus producing energy.
Ethanol has a pretty simple molecular structure. The important part is the Oxygen single bonded to a Hydrogen at the end of the molecule. This O-H bond classifies ethanol as an alcohol. You can also tell that ethanol is an alcohol because both end with the same letters (ol). From everyday experience you will probably know that alcohol is flammable and burns readily. Thus, ethanol will burn and produce energy.
I hope this helps!
