The chemical symbol for lead in its standard state is Pb.
For the one oxidation state. HgNO3 for the two oxidation state. Hg(NO3)2
The symbol for Mercury is Hg. As it is an element, there is no formula for it. However as it can be created during nuclear fusion (Inside a star) you could say there is a formula for making it.
Ethane is a colorless, odorless gas at room temperature and standard pressure. It is a hydrocarbon with the chemical formula C2H6.
Mercury is a liquid at standard temperature and pressure. It has a melting point of -38.83°C and a boiling point of 356.73°C.
The chemical symbol for lead in its standard state is Pb.
For the one oxidation state. HgNO3 for the two oxidation state. Hg(NO3)2
The chemical symbol of zinc is Zn.
Mercury only has a two and one oxidation state. HgO would be the formula for mercury II oxide.
The chemical symbol (not formula) of chlorine is Cl.
The chemical formula for mercury I phosphate is Hg3(PO4)2. In this compound, one mercury ion (Hg+) combines with two phosphate ions (PO4^3-) to form a neutral ionic compound. The Roman numeral I in the name indicates that mercury is in the +1 oxidation state in this compound.
HgI2 (with the '2' small subscript - ie below the line)
The symbol for Mercury is Hg. As it is an element, there is no formula for it. However as it can be created during nuclear fusion (Inside a star) you could say there is a formula for making it.
Assuming the standard 2 oxidation state, Pb(NO3)2
Liquid mercury is a pure element its formula is Hg.
At standard room temperature and pressure the element Mercury (Hg) is in a liquid state.
Ethane is a colorless, odorless gas at room temperature and standard pressure. It is a hydrocarbon with the chemical formula C2H6.
