Answer:
Explanation:
Firstly, it should be noted that melting and freezing points are the same. Thus, when a substance melts at a certain temperature, it means it can also start freezing/solidifying at that same temperature. That been said, <u>when the substance P is a solid at a certain temperature, the other compound Q will boil at that same temperature and hence will be a gas at that same temperature</u>.
To balance the chemical reaction above, we need to remember that the amount of the elements in the reactant side should be equal to the amount of that element in the product side. The balanced chemical reaction is written as:
<span>N2O5 +H2O --->2HNO3</span>
The answer is transition metals because they have no specific charge except for 1 or 2 of them
Answer:
