as a pure metal, or as a cation (in an ionic compound)
If it forms a pure metal does it have a charge or why would it be neutral?
-
CaCO3(s) --> CaCO(s) + CO2(g) As the name implies, something decomposes into something else. Here Calcium Carbonate decomposes to calcium oxide and carbon dioxide
I do not think this is balanced correctly.
-
Carbon dioxide and water are also released if the compound contains carbon.
So will water always be a product of a combustion reaction?
-
In a combustion reaction a compound reacts with oxygen and releases energy.
in a combustion equation is it correct to say the compound that will combust will always contain carbon and hydrogen and oxygen?
-
F2(g) + BaCl2(aq) -> BaF2(g) + Cl2(g)
will we have to predict the form of compounds? (aq, s, g, l, etc)
-
In a double displacement reaction, the ions of two ionic compounds swap counter ions.
Is the charge affected or changed in this type of reaction?

(aq) - aqueous
I understand that 'aqueous' means in water, and I know that you don't just add it to an equation. It is a phase. But I would like to know why it is not added to the equation? How come NaCl(aq) is not NaClH20.
