Put a subscript ed letter or letters in parentheses next to the chemical substance.
(s) is solid (H2O(s) is ice).
(l) is liquid (H2O(l) is liquid water).
(g) is gas (H2O(g) is water vapor).
(aq) means something is dissolved in water (NaCl(aq)).
Density and state of matter are physical properties, its not chemical =p.
The chemical formula for water is H2O.There is not a different formula for the different physical forms of water, however, if you need to specify you can write each as follows (the letter in brackets denotes the state):liquid form: H2O(l)solid form: H2O(s)gas/vapour: H2O(g)
No.
No, melting is a physical change of state, the chemical properties and formula of the substance remain unchanged.
The formula for manganese(II) iodate is Mn(IO3)2. The manganese ion is present in its +2 oxidation state, while iodate is a polyatomic ion with the formula IO3-.
define the following write the units and formula
State symbols are used in chemical equations to indicate the physical state of a substance (s for solid, l for liquid, g for gas, and aq for aqueous solution). To add state symbols to an equation, simply write the appropriate state symbol next to the chemical formula of each substance involved in the reaction. For example, NaCl(s) + H2O(l) -> Na+(aq) + Cl-(aq).
The compound formed from aluminum and sulfur is aluminum sulfide, which has the chemical formula Al2S3. In this compound, aluminum has a +3 oxidation state, while sulfur has a -2 oxidation state.
The formula for platinum(IV) oxide is PtO2. Platinum has a 4+ oxidation state in this compound, which is represented by the Roman numeral IV in its name.
