A prokaryotic cell is a cell without a nucleus (there's more to it, though).
Let's start from the bottom.
Strawberry plant: Plant cells are eukaryotic (cells have nucleus).
Hippopotamus: Animal cells are eukaryotic (cells have nucleus).
Paramecium: That's an animal, and animal cells are eukaryotic (cells have nucleus).
Bacterium: Perfect! Bacterium are prokaryotes! (cells don't have nucleus).
Your answer is bacterium.
Have an awesome day! :)
Tiny organisms known as cyanobacteria, or blue-green algae.
Answer:
ΔG°rxn = +50.8 kJ/mol
Explanation:
It is possible to obtain ΔG°rxn of a reaction at certain temperature from ΔH°rxn and S°rxn, thus:
<em>ΔG°rxn = ΔH°rxn - T×S°rxn (1)</em>
In the reaction:
2 HNO3(aq) + NO(g) → 3 NO2(g) + H2O(l)
ΔH°rxn = 3×ΔHfNO2 + ΔHfH2O - (2×ΔHfHNO3 + ΔHfNO)
ΔH°rxn = 3×33.2kJ/mol + (-285.8kJ/mol) - (2×-207.0kJ/mol + 91.3kJ/mol)}
ΔH°rxn = 136.5kJ/mol
And S°:
S°rxn = 3×S°NO2 + S°H2O - (2×S°HNO3 + S°NO)
ΔH°rxn = 3×0.2401kJ/molK + (0.0700kJ/molK) - (2×0.146kJ/molK + 0.2108kJ/molK)
ΔH°rxn = 0.2875kJ/molK
And replacing in (1) at 298K:
ΔG°rxn = 136.5kJ/mol - 298K×0.2875kJ/molK
<em>ΔG°rxn = +50.8 kJ/mol</em>

Answer:
Rain forest
Explanation:
The rainforest has a very diverse animal kingdom
Answer:
Explanation:
Its simple
This is the number of atoms, ions, or molecules that a central atom or ion holds as its nearest neighbours in a complex or coordination compound or in a crystal.
for example: Sodium chloride (NaCl) or table salt is an ionic compound. It means that each cation will have exactly one anion associated with it, which means the cation Na+ and the anion Cl− have the same number of coordinates.
It may be really confusing at first
I recommend you go online and watch tutorial videos on the topic
