<span>density is an intensive property of the matter, it doesnt change with the change of mass for the same substance, at the same pressure and temperature</span>
It is a number of moles of solute divided by the number of liters of solution! Hope this helps! :D
Answer:
Explanation:
the answer is two electrons im positive
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.
