Answer:
As any molecular or ionic compound, 0 net charge, as a hypothetical diatomic cation, 2+
Explanation:
The question states that this is a compound, and any molecular or ionic compound would have a net charge of 0.
However, such a compound doesn't exist. Francium generally exists in nature having a 1+ charge in its cation form. Combining two francium ions would result in a species which is simply a diatomic ion but not a compound.
Answer:
Explanation:
Hello,
In this case, the increase in the temperature involves the addition of heat that is defined in terms of mass, heat capacity and temperature:
In this case, the heat capacity of iron is 0.450 J/(g*K), thus the heat results:
In such a way, since the temperature is increased heat is added, that is why it is positive.
Best regards.
