2, 4, 1
Explanation:
We have the following chemical reaction:
Ag₂O → Ag + O₂
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.
So the balanced chemical equation is:
2 Ag₂O → 4 Ag + O₂

Answer:
nitrogen fixing bacteria
Explanation:
These bacteria made the nitrogen suitable for plant use.
Answer:


Explanation:
Hello,
Clausius Clapeyron equation is suitable in this case, since it allows us to relate the P,T,V behavior along the described melting process and the associated energy change. Such equation is:

As both the enthalpy and volume do not change with neither the temperature nor the pressure for melting processes, its integration turns out:

Solving for the enthalpy of fusion we obtain:

Finally the entropy of fusion is given by:

Best regards.
Answer:
Molecular
Explanation:
Using the rules for the nomenclature for naming binary covalent (molecular) compounds, the compound SO3 is named sulfur trioxide. The prefix tri- indicates that the oxygen has a subscript of 3 and that a molecule of sulfur trioxide has three oxygen atoms.
