The state of sulfur is solid at 298 K. Sulfur's symbol is S and its atomic number is 16.
Work this out like this Chroium you are told is oxidation state +3. Selenium is in group 16 along with oxygen and sulfur so it will have a preferred oxidation state of -2. Then balance it, oxidation staes can be treated like ionic charges:- Cr2Se3
Heating sulfur is a physical change. You're not changing the chemical composition of the sulfur, just the temperature. Now if you heat it to its boiling point and and it changes to a vapor it's a chemical change because you've changed its state of matter.(Actually changing the state of matter of an object is still a physical change, as it does not change the chemical composition of the element)
Formula: BrN Br in 3+ oxidation state
sulfur is a solid
The chemical symbol (not formula) of mercury is Hg.
The chemical symbol of zinc is Zn.
The state of sulfur is solid at 298 K. Sulfur's symbol is S and its atomic number is 16.
Assuming the standard 2 oxidation state, Pb(NO3)2
S8
No, it's not.A change in the state of matter is a physical change, if that's what you were trying to ask. Usually, anyway. There are a few things for which this may not be true. Liquid sulfur is not exactly the same chemical compound as solid sulfur, and gaseous sulfur is something different again.

The chemical formula for water is H2O. The chemical formula stays the same even if water is in a different state (solid, liquid or gas).
Formula: BrN Br in 3+ oxidation state
Sulfur is solid at room temperature. Its melting point is 115.21 oC, 239.38 °F
